Abstract
Abstract A mattress assembly having a mattress foundation and a mattress selectively attachable to the foundation in position shifting prohibiting relationship. The mattress has a plurality of tuftedtogether layers of differing density foamed material. The layer arranged adjacent the foundation is the most firm, while the layer spaced farthest from the foundation is the softest. A frame provided with a covering layer of foamed material arranged for contacting the mattress forms the foundation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A mattress assembly, comprising, in combination: a. a mattress including a plurality of layers of resilient materials, the mattress layers being three layers of a foamed material, each layer being of a different density from the other layers, with a layer arranged adjacent the foundation being the most firm and a lAyer spaced farthest from the foundation the softest, tufting tying together the three layers, and a tick encasing the tufted layers; b. a mattress foundation including: i. a frame; and ii. a covering layer of resilient material and arranged on the frame for contacting the mattress; and c. the mattress assembly further including means for selectively attaching the mattress to the mattress foundation and prohibiting the mattress from shifting relative to the mattress foundation, the means for attaching including a band connected to the mattress and arranged extending transversely of the mattress, and cooperating fastener elements affixed to the band and mattress foundation.
Claim 2
Dependent Claim
