Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
120 words
A piece of furniture comprising: a pair of spaced, rigid side plates having dimensions which define first and second dimensions of the piece of furniture; a plurality of rods extending between said spaced side plates, said rods comprising the sole means for establishing and maintaining the third dimension of the piece of furniture, said rods being so located on said plates that pairs of rods demarcate the location of generally planar panel elements of the piece of furniture; and a sheet of fabric stressed only in tension in a direction parallel to said side plates, said sheet being affixed solely to at least a pair of said rods for forming a generally planar panel element of the piece of furniture.
Claim 2
Dependent Claim
120 words
