     DETAILED DESCRIPTION 
     According to a first aspect of the present disclosure, a portable cushion support  10  includes a cushion body assembly  20  having a cushion body  22  and a cushion cover  30 , and a support pouch  60  coupled to the cushion cover  30 , as shown in  FIGS.  1 A- 2 B . The support pouch  60  is configured to be stretched over a support surface, for example a bottom surface  113  of a toilet seat lid  112  of a toilet  102  (i.e. the surface  113  of the lid  112  that faces downwardly when the lid  112  is closed on top of a toilet seat  108  of the toilet  102 ), so as to support the cushion body assembly  20 , and thus the portable support cushion  10 , thereon, as shown in detail in  FIGS.  1 B- 2 B . The portable support cushions  10  of the present disclosure provide enhanced versatility, comfort and relaxation, aesthetic appeal, convenience, and/or ease of use. The disclosed support cushions  10  may be beneficial for anyone who spends extended periods of time in area which typically do not provide the utmost comfort, such as the bathroom. For example, the disclosed cushions may be beneficial for parents of small children who experience the need for comfort and relaxation while caring for their children in the bathroom. The support cushions  10  described herein are soft and cushioning, and provide comfort, support, and relaxation for the user  200  while sitting on the toilet  102  or other typically uncomfortable support surfaces. In this manner, the support cushions  10  described herein turn a typical toilet  102  into a relaxing spa-like experience to give the user  200  the opportunity to sit back, relax and unwind. 
     The support cushions  10  described herein also may be reversible to provide a cushioning seat on the top surface  114  of the closed toilet lid  112  (i.e. the surface  114  of the lid  112  that faces upwardly when the lid  112  is closed on top of the toilet seat  108 ), allowing a user  200  to sit on the closed toilet seat lid  112  or providing protection of a toilet tank  116  of the toilet  112  or wall behind the toilet when the seat is opened. When reversed and used as a cushioning seat, the support cushion  10  provides the same comfortable and relaxing experience for the user  200 . Furthermore, the support cushion  10  may be removed from the toilet lid  112  and used as a cushion for kneeling on the floor  92  or other support positions. A person skilled in the art will understand that any reference to toilet seat lids  112  may also refer to other potential support surfaces, such as a chair back or similar seat device. 
     Illustratively, the cushion body  22  may include a pillow or any other soft, compressible, resilient body configured to provide soft yet supportive surface for a user  200 . As can be seen, for example, in  FIGS.  1 A and  3 A , the cushion body  22  can be formed to be  substantially egg-shaped, having a generally oval shape with a bottom portion that is wider and thicker than the top portion of the body  22 . In some embodiments, the cushion body  22  may also include a curved, egg-like shape when viewed from the side, as shown in  FIGS.  3 A and  4 B , having a portion located on the bottom half of the body  22  towards the bottom side  23  that is thicker than the portion located on the top half of the body  22  located towards the top side  24  (see reference numeral  22 E in  FIG.  4 B ). The shape of the cushion body  22  may be formed to substantially match the outer contour of a typical toilet seat lid  112 , which may be egg-shaped as well. A person skilled in the art will understand that the egg-like shape when viewed from the side may be modified to be more or less angled based on the design requirements of the support cushion  10 , so long as the portion located on the bottom half of the body  22  towards the bottom side  23  is thicker than the portion located on the top half of the body  22  located towards the top side  24 . This shaping provides a design that substantially matches the contour of the human lower back lumbar area. 
     In other embodiments, the cushion body  22  may be formed of a different shape based on the intended support surfaces (i.e. various toilet seat lids) and desired design configurations of the support cushion  10 , such as circular, rectangular, or square. The cushion body  22  may be made from any suitable material known in the art. For example, the cushion body  22  may comprise a memory foam or polyurethane material that is molded to form the desired shape of the support cushion  10 , as shown in  FIGS.  3 A and  3 B . In some embodiments, the material of the cushion body  22  may comprise gel, inflatable PVC, and other soft and supportive materials as would be understood by a person skilled in the art. The firmness of the cushion body  22  may be varied to provide the desired level of softness or support. 
       FIGS.  4 A- 4 C  show a non-limiting example of a configuration of the cushion body  22 . In some embodiments, the cushion body  22  may include dimensions that provide good versatility for use with various toilet seat lid  112  shapes and sizes. For example, the cushion body  22  may include a central width  22 A measured at a widest plane  25 A of the body  22  in a range of 300 mm to 350 mm, and in particular, approximately 328 mm. The cushion body  22  may include a central height  22 B measured at a highest, central plane  25 B of the body  22  in a range of 400 mm to 450 mm, and in particular, approximately 429 mm.

A first longitudinal edge  41  of the flap strip  40  is formed as a hinge edge  41  that is directly attached to the cushion cover  30 . A second longitudinal edge  43  of the flap strip  40  opposite the first longitudinal edge  41  is not attached to the cushion cover  30  so as to allow the flap strip  40  to pivot about the hinge edge  41  between an opened arrangement in which the zipper  50  is exposed to a surrounding environment, as shown in  FIG.  7 A , and a closed arrangement in which the zipper  50  is covered, as shown in  FIG.  7 B . In some embodiments, the flap strip  40  may include a plastic layer  42  between an inner portion  44  of the flap strip  40  that is folded over at the second longitudinal edge  43  and an outer portion  45  that extends between the first and second longitudinal edges  41 ,  42 . The plastic layer  42  provides some rigidity such that the flap strip  40  remains in the opened and closed arrangements when moved to these arrangements by the user  200 . 
     As shown in  FIGS.  1 A- 2 B , the portable support cushion  10  is mounted on the toilet seat lid  112  via the support pouch  60  arranged on the rear coves surface  34 . The support pouch  60  is shown in greater detail in  FIGS.  3 A and  5 B- 7 B . Illustratively, the support pouch  60  is changeable between an expanded arrangement, as shown in  FIG.  7 A , and a collapsed arrangement, as shown in  FIG.  7 B . As will be described in greater detail below, the expanded arrangement allows for attachment to the toilet seat lid  112  or other support surface, as shown in  FIGS.  8  and  10   , while the collapsed arrangement allows for usage on a horizontal support surface, such as a floor  92 , as shown in  FIG.  12   . 
     To facilitate mounting strength with the support surface of toilet seat lid  112 , the support pouch  60  may comprise elastic materials such as, for example, Electra Elastic fabric.  The pouch  60  may also be treated with antimicrobials. The elastic material provides greater versatility for the pouch  60  to be attached to a number of different sizes and shapes of toilet lids  112  and support surfaces. Moreover, the elasticity provides enough strength to hold the support cushion  10  in place on the toilet seat lid  112 . Moreover, the elasticity provides enough strength to hold the support cushion  10  in place while the user&#39;s  200  back moves up and down relative to the cushion  10 . In the expanded arrangement, the support pouch  60  is configured to be stretched and arranged around at least a portion of the toilet seat lid  112  such that the elastic force of the elastic material causes the support pouch  60  to grasp the toilet seat lid  112  so as to mount the portable support cushion  10  on the toilet seat lid  112 . 
     The support pouch  60  includes a rear wall  64  and a perimeter side wall  68  arranged to extend between and interconnect the rear wall  64  and the rear cover surface  34 , as shown in detail in  FIGS.  5 B- 6   . An outer contour of the outer edge  65  of the rear wall  64  may be shaped to generally match the outer contour of the cover  30  (i.e. the egg-shaped contour). As shown in  FIGS.  2 B and  5 B , the bottom edge  66  may include a slight curvature, which extends upwardly from its lower terminal end points by a distance  60 E in a range of 20 mm to 30 mm, and in particular, approximately 24 mm. In other embodiments, the bottom edge  66  may be generally straight and level. The perimeter side wall  68  extends between the rear wall  64  and the rear cover surface  34 . In some embodiments, the perimeter side wall  68  extends around the outer edge  65  but not across the bottom edge  66  so as to define a pouch cavity  67  between the rear wall  64 , the perimeter side wall  68 , and the rear cover surface  34 . A pouch opening  69  is defined at the bottom edge  66  and opens into the pouch cavity  67 .

In this way, the support cushion  110  does not touch the toilet seat  108 , thus significantly preventing any undesirable substances or particles front contacting the support cushion  10 . In some embodiments, the topmost point  65 A of the pouch  60  is spaced apart from a topmost point  38 A of the cover  30  by a distance  60 D in a range of 20 mm to 30 mm, and in particular, approximately 25 mm. A person skilled in the art will understand that this distance may be adjusted based on the sizing requirements of the cushion  10 . In some embodiments, the support pouch  60  is arranged on a top half of the rear cover surface  34  such that a bottom half of the rear cover surface  34  is configured to contact the toilet seat lid  112 . 
     In the expanded arrangement, the rear wall  64  of the support pouch is spaced apart from the rear cover surface  34  so as to define the pouch cavity  67 , and, in the collapsed arrangement, the perimeter side wall  68  is collapsed such that the rear wall  64  is located adjacent to the rear cover surface  34 , as shown in  FIGS.  7 A and  7 B . In some embodiments, the rear wall  64  is generally parallel with the rear cover surface  34  so as to form a tight fit with the generally planar toilet seat lid  112 .
