Abstract

A lightweight chair includes an entirely polystyrene foam base support member, a compressible foam overlay member disposed over the base support member, and a cover secured entirely over the overlay member and the base support member. The chair has integral seat and back portions that are configured to prevent the chair from being easily lifted and/or tossed.

What is claimed is: 
     
         1 . A chair, comprising:
 an arm-less and leg-less base support member;   an overlay member disposed over the base support member; and   a cover secured entirely over the overlay member and the base support member.   
     
     
         2 . The chair of  claim 1 , wherein the base support member comprises an entirely polystyrene foam base support member having integral seat and back portions. 
     
     
         3 . The chair of  claim 2 , wherein the overlay member comprises a compressible foam overlay member. 
     
     
         4 . The chair of  claim 1 , wherein the overlay member extends from a front, bottom surface of the base support member to a rear, bottom surface of the base support member. 
     
     
         5 . The chair of  claim 1 , wherein the overlay member is disposed over:
 a forward-facing surface of a seat portion of the base support member;   a seating surface of the seat portion; and   a rearward-facing surface of a back portion of the base support member.   
     
     
         6 . The chair of  claim 1 , wherein the cover is configured to compress edge portions of the overlay member when secured over the overlay member. 
     
     
         7 . The chair of  claim 1 , wherein the base support member is configured without a handle. 
     
     
         8 . A chair, comprising:
 an entirely polystyrene foam base support member;   a compressible foam overlay member disposed over the base support member; and   a cover secured entirely over the overlay member and the base support member.   
     
     
         9 . The chair of  claim 8 , wherein the overlay member comprises a width corresponding to a width of the base support member. 
     
     
         10 . The chair of  claim 8 , wherein the overlay member is disposed over:
 a forward-facing surface of a seat portion of the base support member;   a seating surface of the seat portion; and   a rearward-facing surface of a back portion of the base support member.   
     
     
         11 . The chair of  claim 8 , wherein the overlay member extends from a front, bottom surface of the base support member to a rear, bottom surface of the base support member. 
     
     
         12 . The chair of  claim 8 , wherein the cover is configured to compress edge portions of the overlay member when secured over the overlay member. 
     
     
         13 . The chair of  claim 8 , wherein a transition region extending between a forward-facing surface of a back portion of the base support member and a rearward-facing surface of the back portion is arcuately formed to prevent lifting of the chair by the transition region. 
     
     
         14 . The chair of  claim 13 , wherein a thickness of the back portion is configured to create a chair-centered position of a center of gravity of the chair.
