Abstract
A one-sided mattress assembly includes a core of pocketed coil springs having a layer of resiliently compressible material covering the upper surface thereof and having a bottom surface constructed of a substantially rigid material without a compressible layer. The core of coil springs is preferably attached to the bottom surface only around its periphery. By such a construction the amount of compressible padding is reduced by one-half and consequently the mattress is capable of exhibiting a substantial reduction in the amount of permanent deflection in use. Maintenance of the mattress such as by rotating or turning the mattress over is also avoided.
