Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
161 words
A mattress foundation unit comprising a substantially rectangular, unitary corrugated board enclosure member, the enclosure member having a horizontal, continuous top and a pair of sides and a pair of ends formed integrally with the top and depending therefrom to form a continuous vertical skirt around the periphery of the top, the enclosure member also including end and side supports formed integrally respectively with the enclosure ends and sides, the end and side supports being folded inwardly so as to be disposed in spaced, parallel relation to the top, a longitudinally extending independent hollow corrugated board beam member centrally disposed within the enclosure member, a plurality of transversely extending uncut hollow corrugated board beam members disposed within the enclosure member and passing through the longitudinally extending member at substantially right angles thereto, and means to secure the end and side supports to the ends of the longitudinally and transversely extending beams whereby the latter provide internal reinforcement for the enclosure member.
