The arm rest assembly (e.g., as shown in  FIG. 1 ) may include a vertical portion and a horizontal portion. The horizontal portion of the portion  400  of the arm rest assembly shown in  FIG. 4A , extends inwardly toward a chair seat (not shown) with the vertical portion extending upwardly toward a forearm or elbow of a seated user. The portion  400  of the arm rest assembly may be configured to interface with or couple to a bracket (as shown in  FIGS. 4C-E ) and/or at least one glides  406 . In certain instances, the portion  400  of the arm rest assembly may include notches  402 ,  404  that interface with the glides  406 . 
       FIG. 4B  shows the glides  406 , consistent with various aspects of the present disclosure. The glides  406  may include a snap-feature  408  that is configured to interface with one of the notches  402 ,  404  of the portion  400 . The snap-feature  408  may be a tab that projects inwardly from an exterior surface  410  of the glides  406 . In addition, the glides  406  may include a recessed surface  412  that provides a pathway for the portion  400  of the arm rest assembly shown in  FIG. 4A . in certain instances, the glides  406  may include external features  414  that are configured to engage a bracket  416  as shown in  FIG. 4C . 
       FIG. 4C  shows a top view of the bracket  416  with the portion  400  of arm rest assembly and the glides  406 , shown in  FIGS. 4A-B , consistent with various aspects of the present disclosure. The bracket  416  may be coupled to a lower portion of a chair seat (e.g., as shown in  FIGS. 1-2 ). In addition, the bracket  416  may be configured to releasably couple the arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. In certain instances and as shown in  FIG. 4C , the bracket  416  may be configured to releasably couple the portion  400  of arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. Further, the portion  400  of arm rest assembly may be configured to slide within the bracket  416  for the user to releasably couple the arm rest assembly to the chair seat, and adjust the width for the arm rest assembly relative to the chair seat. 
     As noted above with respect to  FIG. 1 , portions of a chair may be separately packed together for assembly by a user. The user may receive the portions of the chair after purchasing a package containing the chair. In certain instances, the bracket  416  may be separated from the arm rest assembly. Thus, the user may slide the portion  400  of arm rest assembly within the bracket  416  for the user to releasably couple the arm rest assembly to the chair seat. In certain instances, the bracket  416  may be configured to mitigate against removal of the arm rest assembly (e.g., the portion  400  of arm rest assembly) from the bracket  416  subsequent to releasably coupling the arm rest assembly thereto. 
     The glides  406  may be arranged within the bracket  416 . In certain instances, the glides  406  may be snapped into the bracket  416 . As shown in  FIG. 4C , two of the glides  406  are arranged within the bracket  416 . In certain instances, one or more glides  406  are configured to stop the arm rest assembly (e.g., the portion  400  of arm rest assembly) from removal from the bracket subsequent to releasably coupling the arm rest assembly thereto. For example, the notches  402 ,  404  in the portion  400  of arm rest assembly may snap into the snap-feature  408  of the glides  406 . The glides  406  may be configured as a stop for the portion  400  of arm rest assembly such that once the portion  400  of arm rest assembly is pushed passed the snap-feature  408  and the notches  402 ,  404  are engaged, the portion  400  of arm rest assembly may not be removed from the bracket  416  without user intervention. The notches  402 ,  404  are configured to unsnap from the snap-feature  408  of the glides  406  in response to intervention of the user (e.g., the user intentionally forces the snap-feature  408  of the glides  406  out of the notches  402 ,  404 ). 
     The portion  400  of arm rest assembly may be configured to slide within the glides  406  to adjust the width for the arm rest assembly relative to the chair seat. The portion  400  of arm rest assembly may be configured to slide within the glides  406  subsequent to the notches  402 ,  404  being engaged and snapped into the snap-feature  408  of the glides  406 . The portion  400  of arm rest assembly rides on the glides  406  within the bracket  416  to adjust the width without allowing the portion  400  of arm rest assembly to accidently be removed from the bracket  416 . In certain instances, the amount of movement of the portion  400  of arm rest assembly within the bracket  416  is approximately equal to a length of the notches  402 ,  404 . For example, the snap-feature  408  of the glides  406  may be a stop mechanism such that sidewalls of the notches  402 ,  404  contact the snap-feature  408  of the glides  406 , which stops the portion  400  of arm rest assembly from sliding past the snap-feature  408  of the glides  406 , and out of the bracket  416 . 
       FIG. 4D  shows an angled view of the bracket  416  with the portion  400  of arm rest assembly and the glides  406 , shown in  FIGS. 4A-C , consistent with various aspects of the present disclosure. The portion  400  of arm rest assembly may slide within the bracket  416  in the directions indicated by arrow  418 . 
       FIG. 4E  shows a side view of the bracket with the portion of arm rest assembly and the glide, shown in  FIGS. 4A-D , consistent with various aspects of the present disclosure. The recessed surface  412  provides a pathway for the portion  400  of the arm rest assembly. The recessed surface  412  may raise the portion  400  of the arm rest assembly above the bracket  416  for a consistent and smooth pathway for the portion  400  of the arm rest assembly. 
     The illustrative components shown in  FIGS. 4A-E  are not intended to suggest any limitation as to the scope of use or functionality of embodiments of the disclosed subject matter. Neither should the illustrative components be interpreted as having any dependency or requirement related to any single component or combination of components illustrated therein. Additionally, any one or more of the components depicted in any of the  FIGS. 4A-E  may be, in embodiments, integrated with various other components depicted therein (and/or components not illustrated), all of which are considered to be within the ambit of the disclosed subject matter. For example, the bracket  416  may include forming a lever as shown and described below with reference to  FIG. 5  and  FIGS. 6A-B .

In addition, the bracket assembly  500  may be configured to facilitate adjusting a width for the arm rest assembly relative to the chair seat. 
     The arm rest assembly may include an upright having a vertical portion and a horizontal portion as shown in  FIG. 1 . The horizontal portion of the arm rest assembly may be configured to: slide within the bracket assembly  500  for the user to releasably couple the arm rest assembly to the chair seat, and adjust the width for the arm rest assembly relative to the chair seat. As also noted above with respect to  FIG. 1 , portions of a chair may be separately packed together for assembly by a user. The user may receive the portions of the chair after purchasing a package containing the chair. In certain instances, the bracket assembly  500  may be separated from the arm rest assembly. Thus, the user may slide the horizontal portion of arm rest assembly within the bracket  500  for the user to releasably couple the arm rest assembly to the chair seat. 
     The bracket assembly  500  may be configured to mitigate against removal of the arm rest assembly from the bracket subsequent to releasably coupling the arm rest assembly thereto. For example, the bracket assembly  500  may include a bracket portion  502  and glides  504 ,  506  coupled thereto. The glides  504 ,  506  may be configured to stop the arm rest assembly from removal from the bracket subsequent to releasably coupling the arm rest assembly thereto.

     The bracket assembly  500  may also include a lever  512  coupled to the bracket portion  502  and configured to immobilize the arm rest assembly within the bracket. The lever  512  may be configured to actuate between a locked position (as shown in  FIG. 5 ) and an unlocked position. In certain instances, the lever  512  may be configured to push the glides  504 ,  506  inward against the horizontal portion of the arm rest assembly in the locked position to immobilize the arm rest assembly within the bracket. 
       FIG. 6A  shows an example bracket assembly  600  and lever  602  in an unlocked position, consistent with various aspects of the present disclosure. The bracket assembly  600  may be coupled to a chair seat (e.g., as shown in  FIGS. 1-2 ) and configured to releasably couple an arm rest assembly to the chair seat (e.g., as shown in  FIG. 1 ). In addition, the bracket assembly  600  may be configured to facilitate adjusting a width for the arm rest assembly relative to the chair seat. 
     The arm rest assembly may include an upright having a vertical portion and a horizontal portion  604 . The horizontal portion  604  of the arm rest assembly may be configured to slide within the bracket assembly  600  for the user to releasably couple the arm rest assembly to the chair seat. In addition, the bracket assembly  600  may also be configured to allow the horizontal portion  604  to slide therein to adjust the width for the arm rest assembly relative to the chair seat. As also noted above with respect to  FIG. 1 , portions of a chair may be separately packed together for assembly by a user. The user may receive the portions of the chair after purchasing a package containing the chair. In certain instances, the bracket assembly  600  may be separated from the arm rest assembly. Thus, the user may slide the horizontal portion  604  of arm rest assembly within the bracket assembly  600  for the user to releasably couple the arm rest assembly to the chair seat. 
     The bracket assembly  600  may include a lever  602  coupled to the bracket and configured to releasably lock the arm rest assembly (e.g., the horizontal portion  604  of the arm assembly) within the bracket assembly  600  at a desired width for the arm rest assembly relative to the chair seat. In certain instances, the lever  602  may be configured to immobilize the horizontal portion  604  of the arm rest assembly within the bracket assembly  600 . For example, the lever  602  may be configured to compress the horizontal portion  604  of the arm rest assembly against the bracket assembly  600  in the locked position as is shown in  FIG. 6B . In certain instances, the bracket assembly  600  may include glides  606 ,  608  that facilitate movement/sliding of the horizontal portion  604  of the arm rest assembly within the bracket assembly  600 . 
       FIG. 6B  shows the bracket assembly  600  and lever  602 , shown in  FIG. 6A , in a locked position, consistent with various aspects of the present disclosure. The lever  602  may compress portions of the glides  606 ,  608  against the horizontal portion  604  of the arm rest assembly in the locked position. The glides  606 ,  608  are uncompressed when the lever  602  is in the unlocked position. The lever  602  may be configured to rotate, relative to the bracket assembly  600 , between the locked position and the unlocked position. The lever  602  may be attached to the bracket assembly  600  via a pin (e.g., rivet, screw, roll pin) that allows for rotation of the lever  602  relative to the bracket assembly  600 . A user may rotate the lever  602  to the locked position once the horizontal portion  604  of the arm assembly is slid within the bracket assembly  600  such that a desired width for the arm assembly is achieved. 
     The illustrative components shown in  FIGS. 6A-B  are not intended to suggest any limitation as to the scope of use or functionality of embodiments of the disclosed subject matter.

The portion  800  may be a horizontal portion of an arm rest assembly (e.g., as shown in  FIG. 1 ). The portion  800  may extend inwardly toward a chair seat (not shown). The portion  800  of the arm rest assembly may be configured to interface with more a first glide  804   a  and a second glide  804   b  shown in  FIGS. 8B-C . In certain instances, the portion  800  of the arm rest assembly may include a notch  802  that interface with one of the first glide  804   a  and the second glide  804   b.    
     As shown in  FIG. 8B , the first glide  804   a  may include a snap-feature  806  that is configured to interface with the notch  802 . The snap-feature  806  may be a tab that projects inwardly from an exterior surface  810   a  of the first glide  804   a . In addition, the first glide  804   a  may include a recessed surface  812   a  that provides a pathway for the portion  800  of the arm rest assembly shown in  FIG. 8A . In certain instances, the first glide  804   a  may include external features  814   a  that are configured to engage a bracket  816  as shown in  FIG. 8D . 
     As shown in  FIG. 8C , the second glide  804   b  may include an orientation feature  808  that is configured to facilitate orientation of the second glide  804   b  in assembly of a chair. The orientation feature  808  may be positioned within a portion of the bracket  816  to facilitate correct assembly of the second glide  804   b  with the bracket  816  as shown in further detail in  FIG. 8F . In addition, the second glide  804   b  may include an exterior surface  810   b  and a recessed surface  812   b  that provides a pathway for the portion  800  of the arm rest assembly shown in  FIG. 8A . In certain instances, the second glide  804   b  may include external features  814   b  that are configured to engage the bracket  816  as shown in  FIG. 8D . 
       FIG. 8D  shows a top view of the bracket  816  with the portion  800  of arm rest assembly, the first glide  804   a , and the second glide  804   b , shown in  FIGS. 8A-C , consistent with various aspects of the present disclosure. The bracket  816  may be coupled to a lower portion of a chair seat (e.g., as shown in  FIGS. 1-2 ). In addition, the bracket  816  may be configured to releasably couple the arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. In addition, the bracket  816  may be configured to releasably couple the portion  800  of arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. The portion  800  of arm rest assembly may be configured to slide within the first glide  804   a  and the second glide  804   b  (within the bracket  816 ) for the user to releasably couple the arm rest assembly to the chair seat, and adjust the width for the arm rest assembly relative to the chair seat. 
     In addition, the portions of a chair may be separately packed together for assembly by a user (e.g., as noted above with respect to  FIG. 1 ). The user may receive the portions of the chair after purchasing a package containing the chair. In certain instances, the bracket  816 , the first glide  804   a , and/or the second glide  804   b  may be separated from the arm rest assembly. The user may attach the first glide  804   a  and the second glide  804   b  to the bracket  816 . The orientation feature  808  may visually indicate to the user the correct orientation for locating the second glide  804   b  within the bracket  816 . Due to the symmetrical nature of the second glide  804   b  and the first glide  804   a , the user may deduce the orientation for arranging the first glide  804   a  within the bracket  816 . 
     In certain instances, the first glide  804   a  may be configured to stop the arm rest assembly (e.g., the portion  800  of arm rest assembly) from removal from the bracket subsequent to releasably coupling the arm rest assembly thereto. For example, the notch  802  in the portion  800  of arm rest assembly may snap into the snap-feature  806  of the first glide  804   a . The first glide  804   a  may be configured as a stop for the portion  800  of arm rest assembly such that once the portion  800  of arm rest assembly is pushed passed the snap-feature  806  and the notch  802  are engaged, the portion  800  of arm rest assembly may not be removed from the bracket  816  without user intervention. The notch  802  may be configured to unsnap from the snap-feature  806  of the first glide  804   a  in response to intervention of the user (e.g., the user intentionally forces the snap-feature  806  of the first glide  804   a  out of the notch  802 ). In certain instances, the amount of movement of the portion  800  of arm rest assembly within the bracket  816  is approximately equal to a length of the notch  802 . For example, the snap-feature  806  of the first glide  804   a  may be a stop mechanism such that sidewalls of the notch  802  contact the snap-feature  806  of the first glide  804   a , which stops the portion  800  of arm rest assembly from sliding past the snap-feature  806  of the first glide  804   a , and out of the bracket  816 . 
       FIG. 8E  shows an angled view of the bracket  816  with the portion  800  of arm rest assembly and the first glide  804   a  and the second glide  804   b , shown in  FIGS. 8A-D , consistent with various aspects of the present disclosure. The portion  800  of the arm rest assembly may slide within the bracket  816  in the directions indicated by arrow  818 . 
       FIG. 8F  shows a side view of the bracket  816  with the portion  800  of arm rest assembly and the first glide  804   a  and the second glide  804   b , shown in  FIGS. 8A-E , consistent with various aspects of the present disclosure. The recessed surfaces  812   a ,  812   b  of the first glide  804   a  and the second glide  804   b  provide a pathway for the portion  800  of the arm rest assembly. The recessed surfaces  812   a ,  812   b  may raise the portion  800  of the arm rest assembly above the bracket  816  for a consistent and smooth pathway for the portion  800  of the arm rest assembly.

The bracket assembly  900  may be coupled to a chair seat (e.g., as shown in  FIGS. 1-2 ) and configured to releasably couple an arm rest assembly to the chair seat (e.g., as shown in  FIG. 1 ). In addition, the bracket assembly  900  may be configured to facilitate adjusting a width for the arm rest assembly relative to the chair seat. 
     The bracket assembly  900  may be configured to mitigate against removal of an arm rest assembly from the bracket subsequent to releasably coupling the arm rest assembly thereto. For example, the bracket assembly  900  may include a bracket portion  902  and glides  904   a ,  904   b  coupled thereto. The glides  904   a ,  904   b  may be configured to stop the arm rest assembly from removal from the bracket subsequent to releasably coupling the arm rest assembly thereto. One of the glides  904   a ,  904   b  (glide  904   a ) may include a snap-feature  908  that couple to parts of the horizontal portion of arm rest assembly and which may provide a stop for the horizontal portion of arm rest assembly (e.g., as detailed above with reference to  FIGS. 4A-E  and  FIGS. 8A-F ). The other of the glides  904   a ,  904   b  (glide  904   b ) may include an orientation feature  906 . The orientation feature  906  may visually indicate to the user the correct orientation for locating the glide  904   b  within the bracket portion  902 . 
     The bracket assembly  900  may also include a lever  912  coupled to the bracket portion  902  and configured to immobilize the arm rest assembly within the bracket. The lever  912  may be configured to actuate between a locked position (as shown in  FIG. 9 ) and an unlocked position. In certain instances, the lever  912  may be configured to push the orientation feature  906  of the glide  904   b  inward against the horizontal portion of the arm rest assembly in the locked position to immobilize the arm rest assembly within the bracket. The orientation feature  906  may facilitate frictional engagement between the horizontal portion of the arm rest assembly and the lever  912 . 
       FIG. 10A  shows an example bracket assembly  1000  and lever  1002  in an unlocked position, consistent with various aspects of the present disclosure. The arm rest assembly may include an upright having a vertical portion and a horizontal portion  1004 . The bracket assembly  1000  may also be configured to allow the horizontal portion  1004  to slide therein to adjust the width for the arm rest assembly relative to the chair seat. In addition, the horizontal portion  1004  of the arm rest assembly may be configured to slide within the bracket assembly  1000  for the user to releasably couple the arm rest assembly to the chair seat. 
     The bracket assembly  1000  may include a lever  1002  coupled to the bracket and configured to releasably lock the arm rest assembly (e.g., the horizontal portion  1004  of the arm assembly) within the bracket assembly  1000  at a desired width for the arm rest assembly relative to the chair seat. In certain instances, the lever  1002  may be configured to immobilize the horizontal portion  1004  of the arm rest assembly within the bracket assembly  1000 . For example, the lever  1002  may be configured to compress the horizontal portion  1004  of the arm rest assembly against the bracket assembly  1000  in the locked position as is shown in  FIG. 6B . In certain instances, the bracket assembly  1000  may include glides  1006 ,  1008  that facilitate movement/sliding of the horizontal portion  1004  of the arm rest assembly within the bracket assembly  1000 . Glide  1006  may include a snap-fit feature  1010  (e.g., as discussed above with reference to  FIGS. 8-9 ). In addition and as shown in  FIG. 10A , the glide  1008  includes a flat surface  1012  opposite that of the snap-fit feature  1010  that may facilitate the lever  1002  engaging the horizontal portion  1004  to lock the horizontal portion  1004  within the bracket assembly  1000 . 
       FIG. 10B  shows the bracket assembly  1000  and the lever  1002 , shown in  FIG. 10A , in a locked position, consistent with various aspects of the present disclosure. The lever  1002  may compress the flat surface  1012  of the glide  1008  against the horizontal portion  1004  of the arm rest assembly in the locked position. The glides  1006 ,  1008  are uncompressed when the lever is in the unlocked position. The lever  1002  may be configured to rotate, relative to the bracket assembly  1000 , between the locked position and the unlocked position. The lever  1002  may be attached to the bracket assembly  1000  via a pin (e.g., rivet, screw, roll pin) that allows for rotation of the lever  1002  relative to the bracket assembly  1000 . A user may rotate the lever  1002  to the locked position once the horizontal portion  1004  of the arm assembly is slid within the bracket assembly  1000  such that a desired width for the arm assembly is achieved. 
       FIG. 11  shows another example bracket  1100 , consistent with various aspects of the present disclosure. The bracket  1100  may include one or more holes  1102  to facilitate attachment of the bracket  300  to a chair seat (e.g., as shown in  FIGS. 1-2 ). The bracket  1100  may be secured to the chair seat (not shown) by one or more attachment mechanisms (such as screws, bolts, rivets, or other similar devices) arranged through the holes  1102  and into the chair seat. 
     In certain instances, the bracket  1100  includes openings  1104 ,  1106  (as also shown in  FIG. 3B , for example) that are attachment holes for attachment of a lever (e.g., as shown in  FIGS. 6A-B ) through the bracket  110  to the chair seat (not shown). Further, the bracket  1100  may also include features  1108 ,  1110  that facilitate coupling of glides (not shown) to the bracket  1110 . The glides may include corresponding features (e.g., as shown in  FIGS. 13A-B ) that facilitate assembly of the glides with the bracket  1110  in a proper and desired arrangement. In addition, the bracket  1100  can include a hole  1112  that facilitates coupling and removal of the bracket  110  from a die carrier. Upper portions of the bracket  1100  may include cut-outs  1114 ,  1116  adjacent to openings  1110  that are near the perimeter of the bracket  1110 . The cut-outs  1114 ,  1116  facilitate use of a driver or other tool to arrange attachment mechanisms (such as screws, bolts, rivets, or other similar devices) through the openings  1110 . 
       FIGS. 12A-D  shows views of another example first glide  1200 , consistent with various aspects of the present disclosure. The first glide  1200  include a guide-feature  1202  that is configured to interface with a notch in a bracket (e.g., as shown in  FIGS. 14-15 ). The guide-feature  1202  may be a tab that projects from an exterior surface  1204  of the first glide  1200 . The exterior surface  1204  of the first glide  1200  interfaces with a bracket and does not provide a slideable pathway for a portion of the arm rest assembly shown in  FIGS. 15-17 . An interior surface  1206  of the first glide  1200  provides a slideable pathway for a portion of the arm rest assembly shown in  FIGS. 15-17 . 
     The first glide  1200  may also include an orientation feature  1208  that prevents the installation of a lever (e.g., as shown in  FIG. 19 ) on an improper or undesired side of the bracket. The orientation feature  1208  is located on the exterior surface  1204  of the first glide  1200  vertically offset from the guide-feature  1202  to slow within a bracket as shown in  FIG. 14 . The guide-feature  1202  and the orientation feature  1208  facilitate proper alignment and orientation of the first glide  1200  within a bracket during assembly. 
     Along the interior surface  1206  of the first glide  1200  may be a stop mechanism  1210 . The stop mechanism  1210  projects inwardly relative to the interior surface  1206  (slideable surface) of the first glide  1206 . The stop mechanism  1210  is configured to interface with a portion of the of arm rest assembly to stop the portion of the of arm rest assembly from sliding past the stop mechanism  1210  of the first glide  1200 , and out of the bracket as is discussed in further detail with reference to  FIG. 18 . The stop mechanism  1210  includes an inward stop  1210   a  and an outward stop  1210   b  for bidirectional adjustment of the portion of the arm rest assembly. 
       FIGS. 13A-B  show views of another example second glide  1300 , consistent with various aspects of the present disclosure. The second glide  1300  includes an orientation feature  1302  that is configured to facilitate orientation of the second glide  1300  in assembly of a chair. The orientation feature  1302  may be positioned within a portion of the bracket (not shown) to facilitate correct assembly of the second glide  1300  with the bracket as shown in further detail in  FIG. 14 . In addition, the second glide  1300  may include an interior surface  1304  that provides a pathway for a portion of the arm rest assembly. 
     Similar to the orientation feature  1208  of the first glide  1200  shown in  FIGS. 12A-D , the orientation feature  1302  prevents upside-down installation of the second glide  1300 . In addition, the orientation feature  1302  also provides surface for lever (shown in  FIG. 19 ) to act on. In certain instances, the second glide  1300  may include an additional feature  1306  that interfaces with a portion of a bracket (features  1108 ,  1110  shown in  FIG. 11 ) to guide installation of the second slide  1300  into engagement with the bracket. 
       FIG. 14  shows another example bracket  1100  and glides  1200 ,  1300 , consistent with various aspects of the present disclosure. In certain instances, the bracket  1100  may include the glides  1200 ,  1300  to facilitate adjusting the width for the arm rest assembly relative to the chair seat. The glides  1200 ,  1300  may be configured as a pathway for a horizontal portion of the arm rest assembly to slide. The pathway provided by the surface  1206 ,  1304  of the glides  1200 ,  1300  is raised relative to a lower surface  1400  of the bracket  1100 . In addition, the glides  1200 ,  1300  may provide a level horizontal pathway through which the horizontal portion of the arm rest assembly may slide. The glides  1200 ,  1300  may grip and at least partially surround the horizontal portion of the arm rest assembly to facilitate sliding thereof. An orientation feature  1208  of the first glide  1200  may slot within the bracket  1100 . The second glide  1300  includes a similar orientation feature  1302  to slot within the bracket  1100 . 
       FIG. 15  shows an angled view of an example bracket  1100 , a portion of arm rest assembly  1500 , which can also be referred to as a horizontal portion of the arm rest, and glides  1200 ,  1300 , consistent with various aspects of the present disclosure. The portion  1500  of the arm rest assembly may slide within the bracket  1100 . 
       FIG. 16  shows a side view of an example bracket  1100 , a portion of arm rest assembly  1500 , and glides  1200 ,  1300 , consistent with various aspects of the present disclosure. Interior or recessed surfaces of the first glide  1200  and the second glide  1300 , as discussed in further detail above, provide a pathway for the portion  1500  of the arm rest assembly. The recessed surfaces may raise the portion  1500  of the arm rest assembly above the bracket  1100  for a consistent and smooth pathway for the portion  1500  of the arm rest assembly. 
     In addition, the glides  1200 ,  1300  may be both vertically and laterally offset from the bracket  1100  to provide clearance above attachment mechanisms  1600  used to attach the bracket  1100  to a chair seat. The glides  1200 ,  1300  being configured in this manner further facilitates a the consistent and smooth pathway for the portion  1500  of the arm rest assembly. 
       FIG. 17  shows a portion  1500  of an example arm rest assembly, consistent with various aspects of the present disclosure, as discussed above with reference to  FIGS. 15-16 . The portion  1500  may be a horizontal portion of an arm rest assembly (e.g., as shown in  FIG. 1 ). The portion  1500  may extend inwardly toward a chair seat (not shown). The portion  1500  of the arm rest assembly may be configured to interface glides as discussed in detail above. In certain instances, the portion  1500  of the arm rest assembly may include a notch  1700  that interface with one of the glides. 
     In certain instances, the first glide  1200  may be configured to stop the arm rest assembly (e.g., the portion  1500  of arm rest assembly) from removal from the bracket  1100  (not shown in  FIG. 17 ) subsequent to releasably coupling the arm rest assembly thereto. For example, the notch  1700  in the portion  1500  of arm rest assembly may interface with a stop mechanism  1210  of the first glide  1200 . The first glide  1200  may be configured as a stop for the portion  1500  of arm rest assembly such that once the portion  1500  of arm rest assembly is pushed passed the stop mechanism  1210  and the notch  1700  are engaged, the portion  1500  of arm rest assembly may not be removed from the bracket without user intervention. The notch  1700  may be configured to unsnap from the stop mechanism  1210  of the first glide  1200  in response to intervention of the user (e.g., the user intentionally forces the stop mechanism  1210  of the first glide  1200  out of the notch  1700 ). In certain instances, the amount of movement of the portion  1500  of arm rest assembly within the bracket  1100  (not shown in  FIG. 17 ) is approximately equal to a length of the notch  1700 . For example, the stop mechanism  1210  of the first glide  1200  may be a stop mechanism such that sidewalls of the notch  1700  contact the stop mechanism  1210  of the first glide  1200 , which stops the portion  1500  of arm rest assembly from sliding past the stop mechanism  1210  of the first glide  1200 , and out of the bracket. As noted above, the stop mechanism  1210  includes an inward stop  1210   a  and an outward stop  1210   b  for bidirectional adjustment of the portion  1500  within the notch  1700 . 
     In certain instances, the portion  1500  of arm rest assembly includes lead-ins  1702 ,  1704  that facilitate installation of the portion  1500  of arm rest assembly within the glides  1200 ,  1300  (not shown in  FIG. 17 ). In addition, the portion  1500  of arm rest assembly may include stop-features  1706 ,  1708  that are configured to facilitate placement and stopping movement of the portion  1500  of arm rest assembly within the glides. The stop-features  1706 ,  1708  of the portion  1500  of arm rest assembly project inwardly and contact a surface of the glides  1200 ,  1300  to assist the stop mechanism  1210  of the first glide  1200  as shown in further detail with reference to  FIG. 18 . 
       FIG. 18  shows a top view of an example bracket  100  with a portion  1500  of arm rest assembly, and glides  1200 ,  1300 , consistent with various aspects of the present disclosure. The bracket  1100  may be coupled to a lower portion of a chair seat (e.g., as shown in  FIGS. 1-2 ). In addition, the bracket  1100  may be configured to releasably couple the arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. The bracket  1100  may also be configured to releasably couple the portion  1500  of arm rest assembly to the chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat. The portion  1500  of arm rest assembly may be configured to slide within the first glide  1200  and the second glide  1300  (within the bracket  1100 ) for the user to releasably couple the arm rest assembly to the chair seat, and adjust the width for the arm rest assembly relative to the chair seat. 
     In addition, the portions of a chair may be separately packed together for assembly by a user (e.g., as noted above with respect to  FIG. 1 ). The user may receive the portions of the chair after purchasing a package containing the chair. In certain instances, the bracket  1100 , the first glide  1200 , and/or the second glide  1300  may be separated from the arm rest assembly. The user may attach the first glide  1200  and the second glide  1300  to the bracket  1100  using the various orientation and alignment features discussed in further detail above. 
       FIG. 19  shows another example bracket assembly  1900 , consistent with various aspects of the present disclosure. The bracket assembly  1900  may be coupled to a chair seat (e.g., as shown in  FIGS. 1-2 ) and configured to releasably couple an arm rest assembly to the chair seat (e.g., as shown in  FIG. 1 ). In addition, the bracket assembly  1900  may be configured to facilitate adjusting a width for the arm rest assembly relative to the chair seat. 
     The bracket assembly  1900  may be configured to mitigate against removal of an arm rest assembly from the bracket subsequent to releasably coupling the arm rest assembly thereto. For example, the bracket assembly  1900  may include a bracket  1100  and glides  1200 ,  1300  coupled thereto. The glides  1200 ,  1300  may be configured to stop the arm rest assembly from removal from the bracket  1100  subsequent to releasably coupling the arm rest assembly thereto. 
     The bracket assembly  900  may also include a lever  1902  coupled to the bracket  1100  and configured to immobilize the arm rest assembly within the bracket. The lever  1902  may be configured to actuate between a locked position (as shown in  FIG. 19 ) and an unlocked position. In certain instances, the lever  1902  may be configured to push an orientation feature of the glide  1300  (as discussed in detail above) inward against the horizontal portion of the arm rest assembly in the locked position to immobilize the arm rest assembly within the bracket. The orientation feature may facilitate frictional engagement between the horizontal portion of the arm rest assembly and the lever  1902 . The lever  1902  is arranged, relative to the bracket  1100 , to move clear of the chair seat and aspects of the chair seat (e.g., upholstery).
