Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A box-spring assembly for use with a conventional bed frame for cooperatively receiving a mattress comprising two pairs of longitudinally extending side support members and at least one pair of intermediate support members, said pairs of support member being spacially aligned and having a top and bottom portion with resilient means therebetween, each resilient means being spaced from said support members by independent upper and lower guard means, said guard means having a hardness greater than said support member, said guard member having sufficient area dimensions to protect said support member when said resilient member is in its compressed configuration, said top portion includes a series of apertures for access to said resilient means, a plurality of transverse bracing members connected to said pairs of support members to maintain spacial alignment of said support members whereby the weight from a mattress placed thereon will be evenly distributed.
