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.
Claims23
A one-sided inner spring mattress assembly comprising:
- a central core of individual fabric pocketed coil springs arranged in a Marshall coil type assembly;
- an upper assembly padding layer extending over a top surface of said core;
- a lower relatively rigid layer underlying said core;
- wherein said lower layer is resistant to compression by the central core of pocketed springs and comprises a. high density polyurethane foam having a weight of about 1.85 lbs per cubic foot and a firmness in the range of about 45 ILD to about 60 ILD.
A one-sided inner spring mattress assembly comprising:
- a central core of closely positioned individual pocketed coil springs surrounded at a bottom edge by and connected to a border wire;
- an upper padding layer overlying the central core;
- and
- a bottom relatively rigid layer underlying the core;
- wherein said border wire is attached to said bottom layer to hold said bottom layer to said core.
An innerspring mattress comprising:
- a core of individual springs each pocketed in fabric and arranged together to define a unitary spring assembly;
- a border wire positioned adjacent a bottom edge of said core and extending around the periphery of said core, said border wire being connected to said spring assembly;
- a layer of relatively incompressible material underlying said spring assembly,
- wherein said layer is connected only to said border wire to attach said layer to said spring assembly.
A one-sided inner spring mattress assembly comprising;
- a central core of closely positioned individual coil springs surrounded at a bottom edge by and connected to a border wire;
- an upper padding layer overlying the central core;
- and
- a bottom relatively rigid layer underlying the core;
- wherein said border wire is attached to said bottom layer to hold said bottom layer to said core.
