       FIG. 2  shows a non-corner furniture unit  104  including a first surface or a support surface  124  for seating and a second surface or a support surface  126  for back support. The support surface  124  for seating includes a generally square-shaped and flat surface. The material for the support surface  124  for seating may include plywood, wood or other building material that may be formed to create a square-shaped flat surface. The non-corner furniture unit  104  also includes a back panel  128  that forms a generally square-shaped and flat surface. The material for the back panel  128  may include plywood, wood or other building material that may be formed to create a square-shaped flat surface. The support surface  124  for seating is connected to the back panel  128 , which is arranged perpendicular to the support surface  124  for seating. For example, the support surface  124  for seating is positioned in an x-plane or horizontal plane  130  and the back panel  128  is positioned in a y-plane or vertical plane  132 . 
     The non-corner furniture unit  104  also includes a pair of side panels  134  that are positioned on the support surface  124  for seating and adjacent to opposing edges  150  of the support surface  124 . The pair of side panels  134  are positioned in the vertical plane  132  and extend from the back panel  128  in the direction of the horizontal plane  130 , as shown in  FIG. 2 . The material for the pair of side panels  134  may include plywood, wood or other building material that may be formed to create a flat surface. The pair of side panels  134  each include first  136  and second  138  edges that are generally flat and form a 90 degree angle with each other. The pair of side panels  134  also each include a third edge  140  that is curved or generally convex and extends from the first edge  136  to the second edge  138 . 
     The support surface  126  for back support comprises a rigid contoured element that is vacuum molded. The material for the support surface  126  may include a thermoplastic, a plastic, or other material capable of being vacuum molded. The support surface  126  for back support extends from the support surface  124  for seating along the third edge  140  of each of the pair of side panels  134  to the back panel  128 . The support surface  126  for back support is contoured to align with the curved or generally convex third edge  140  of each of the pair of side panels  134 . The support surface  126  is connected to the third edge  140  of each of the pair of side panels  134  and may also be connected to a top portion of the back panel  128  to form an enclosed space. The support surface  126  may be connected to the third edge  140  of each of the pair of side panels  134  and the top portion of the back panel  128  by any form of connection that binds them together, including any form of mechanical connection such as screws, bolts, or nails and/or any form of adhesive or permanent connection such as glue or paste. 
     To adhere upholstery to the non-corner furniture unit  104 , an embodiment of an upholstery system  141  includes a plurality of clips  142  that are arranged on the support surface  124  for seating in a series along a z-plane  144  and on the support surface  126  for back support in a series along the z-plane  144 , as shown in  FIG. 2 . The z-plane  144  is perpendicular to the horizontal plane  130  and to the vertical plane  132 . The plurality of clips  142  are spaced apart from each other within the series and may include individual clips, such as shown in  FIGS. 12-13, 15 and 17-19  or the plurality of clips  142  may be arranged on an elongated bracket or strip  146 , such as show in  FIGS. 2, 9A-9C and 10 .  FIG. 12  shows a perspective view of an individual clip  142 . The plurality of clips  142  positioned on the support surface  124  for seating are positioned a length  148  from opposing edges  150  of the support surface  124  and a length  152  from a corner  154  where the support surface  124  for seating and the support surface  126  for back support meet. Similarly, the plurality of clips  142  positioned on the support surface  126  for back support are positioned a length  156  from opposing edges  158  of the support surface  126  for back support and a length  160  from the corner  154 . In one embodiment, the plurality of clips  142  are adhesively connected to the support surface  124  for seating and the support surface  126  for back support, and in a second embodiment, the plurality of clips  142  are mechanically connected to the support surface  124  for seating and the support surface  126  for back support. 
     The upholstery system  141  also includes a plurality of contoured elements  162 . The material of the plurality of contoured elements  162  includes any type of foam, such as polyurethane, high density, closed cell, latex rubber, or high resilience foam, or any type of cushion material that provides a firm and resilient surface. The plurality of contoured elements  162  each include a plurality of surfaces and are shaped to align with the shape of the corner  154  where the support surface  124  for seating and the support surface  126  for back support meet. The plurality of contoured elements  162  are adhesively connected to the support surface  124  for seating and the support surface  126  for back support. 
     A first surface  164  of the plurality of contoured elements  162  is generally flat and positioned along the support surface  124  for seating for a length  165 . A second surface  166  of the plurality of contoured elements  162  is generally flat and positioned along the support surface  126  for back support for a length  167  as shown in  FIG. 8 . The second surface  166  extends at an angle  168  from the first surface  164 . In one embodiment, as shown in  FIG. 2 , the angle  168  is greater than 90 degrees from the first surface  164 , and in a second embodiment, the angle  168  is approximately equal to 90 degrees from the first surface  164 . A third surface  170  of the plurality of contoured elements  162  extends from the second surface  166  for a length  171  and away from the support surface  126  for back support. The third surface  170  is generally flat and generally parallel to the support surface  124  for seating. A fourth surface  172  of the plurality of contoured elements  162  extends for a length  173  from the first surface  164  and away from the support surface  124  for seating. The fourth surface  172  is generally flat and generally parallel to the back panel  128 . A fifth surface  174  of the plurality of contoured elements  162  includes a curved and convex shape that extends between the third surface  170  and the fourth surface  172 . The plurality of contoured elements also includes a pair of opposing surfaces  176  that extend from the first surface  164  and the second surface  166  to the fifth surface  174 , as shown in  FIG. 2 . 
     The plurality of contoured elements  162  is positioned along the corner  154  where the support surface  124  for seating and the support surface  126  for back support meet. In other words, the first surface  164  of each of the plurality of contoured elements  162  is flush against the support surface  124  for seating and the second surface  166  of each of the plurality of contoured elements  162  is flush against the support surface  126  for back support. 
     Two of the plurality of contoured elements  162 , also referred to as the pair of end contoured elements  162   a  are positioned adjacent to the opposing edges  150  of the support surface  124 , and one or more of the plurality of contoured elements  162 , also referred to as the middle contoured elements  162   b , are positioned between the pair of end contoured elements  162   a  and spaced apart from each other. For reasons described below, the dimensions of the pair of end contoured elements  162   a  are greater than the middle contoured elements  162   b , and the shape of the pair of end contoured elements  162   a  and the middle contoured elements  162   b  is the same as described above for the plurality of contoured elements  162 . For example, the length  165  of the first surface  164  of the pair of end contoured elements  162   a  is greater than the length  165  of the first surface  164  of the middle contoured elements  162   b , and the length  167  of the second surface  166  of the pair of end contoured elements  162   a  is greater than the length  167  of the second surface  166  of the middle contoured elements  162   b.    
     One of the pair of end contoured elements  162   a  is positioned adjacent to one of the opposing edges  150  of the support surface  124  such that there is minimal to no distance between the opposing edge  150  and the end contoured element  162   a . The second of the pair of end contoured elements  162   a  is also positioned adjacent to the other of the opposing edges  150  of the support surface  124  such that there is minimal to no distance between the opposing edge  150  and the least one of the plurality of contoured elements  162 . In one embodiment, the distance between adjacent contoured elements  162  is generally equal. In other embodiments, the distance between adjacent contoured elements  162  may vary depending on the shape of the support surface  126  for back support of the furniture unit  102 . 
     The upholstery system  141  also includes a first planar element  178  and a second planar element  180 , as shown in  FIG. 3 , that are each generally flat and squared-shaped. The material of the first planar element  178  and the second planar element  180  includes any type of foam, such as polyurethane, high density, closed cell, latex rubber, or high resilience foam, or any type of cushion material that provides a firm and resilient surface. 
     The first planar element  178  is positioned on the support surface  124  for seating and adjacent to the fourth surface  172  of the pair of end contoured elements  162   a  such that the pair of end contoured elements  162   a  and the first planar element  178  form a continuous surface. Specifically, the first planar element  178  has a height  179 , and the height  179  of the first planar element  178  is the same as the length  173  of the fourth surface  172 , as shown in  FIG. 8 . The first planar element  178  is adhesively connected to the support surface  124  for seating. As described above, the middle contoured elements  162   b  have smaller dimensions than the pair of end contoured elements  162   a . Thus, a gap  182  having a width  183  exists between the first planar element  178  and the fourth surface  172  of the middle contoured elements  162   b . The width  183  of the gap  182  is minimal yet sufficient to allow the plurality of clips  142  to be positioned between the first planar element  178  and the fourth surface  172  of the middle contoured elements  162   b.    
     The second planar element  180  is positioned on the support surface  126  for back support and adjacent to the third surface  170  of the plurality of contoured elements  162 .
