Stackable chair

Abstract

The present invention discloses a stackable chair that can be used to stack up to ten of the stackable chairs in a generally vertical direction. The stackable chair can include a chair frame that has a seat support section with a front leg and a back leg extending in a downward direction therefrom. A cushion can be attached to the seat support section, the cushion having a rigid perimeter layer and a cushion layer extending across the rigid perimeter layer. The rigid perimeter layer can also have a central aperture and a support structure that extends across the aperture. The rigid perimeter layer provides a suitable structure such that a plurality of chairs can be stacked on top of each other in a generally vertical direction.

1 . A stackable chair comprising:
 a chair frame having a seat support section with a front leg and a back leg extending in a downward direction therefrom;   a cushion attached to said seat support section;   said cushion having a base layer located above said seat support section of said chair frame;   said cushion also having a rigid perimeter layer spaced apart from said base layer and a cushion layer extending across said rigid perimeter layer, said rigid perimeter layer having a central aperture and a support structure extending across said central aperture;   whereby said rigid perimeter layer and said cushion layer allows a plurality of said chairs to be stacked on each other in a generally vertical direction.   
   
   
       2 . The chair of  claim 1 , further comprising a lift layer between said base layer and said rigid perimeter layer. 
   
   
       3 . The chair of  claim 1 , wherein said support structure contains a plurality of elongated elastic strips extending across said central aperture. 
   
   
       4 . The chair of  claim 1 , wherein said support structure contains a plurality of springs extending across said central aperture. 
   
   
       5 . The chair of  claim 1 , wherein said cushion layer is made of high density foam. 
   
   
       6 . The chair of  claim 1 , wherein said cushion layer has a thickness less than 50% of an overall thickness of said cushion. 
   
   
       7 . The chair of  claim 1 , further comprising a wrapping layer extending around an outer perimeter of said cushion. 
   
   
       8 . A stackable chair comprising:
 a chair frame having a seat support section with a front leg and a back leg extending in a downward direction therefrom;   a cushion attached to said seat support section;   said cushion having a base layer, a rigid perimeter layer spaced apart from and above said base layer and a cushion layer extending across and above said rigid perimeter layer;   said rigid perimeter layer having a central aperture and a support structure extending across said central aperture, whereby said rigid perimeter layer provides a generally rigid perimeter surface for stacking a plurality of said chairs on top of each other in a generally vertical direction with said seat support section of one chair stacked on top of a cushion of another chair.   
   
   
       9 . The chair of  claim 8 , further comprising a lift layer between said base layer and said rigid perimeter layer. 
   
   
       10 . The chair of  claim 8 , wherein said support structure is a plurality of elongated elastic strips extending across said central aperture. 
   
   
       11 . The chair of  claim 8 , wherein said support structure is a plurality of springs extending across said central aperture. 
   
   
       12 . The chair of  claim 8 , wherein said cushion layer is made of high density foam. 
   
   
       13 . The chair of  claim 8 , wherein said cushion layer has a thickness less than 50% of an overall thickness of said cushion. 
   
   
       14 . The chair of  claim 8 , further comprising a wrapping layer extending around an outer perimeter of said cushion. 
   
   
       15 . The chair of  claim 14 , wherein said wrapping layer extends from said rigid perimeter layer to below said base layer.
