Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A foam foundation unit for bedding comprising a base frame member formed of a pair of longitudinal side frame members and a pair of transverse end frame members joined one to the other to provide a base frame of rectangular shape, a plurality of longitudinally spaced apart slats extending crosswise between the longitudinal side frame members, a grid of spaced crosswise and lengthwise extending metal members, and means fixedly securing the grid directly to the slats and the base frame members at points where the grid crosses over the slats at base frame members, and a foam layer supported on the top side of the grid.
Claim 2
Dependent Claim
