Stackable bedding foundation having pocketed topper

Abstract

A nestably stackable spring assembly is incorporated into a bedding foundation. The foundation includes a pocketed spring assembly which functions as a cushioning layer, thereby providing additional comfort. The spring assembly includes a number of corrugated support wires having alternating flattened peaks and valleys. The pocketed spring assembly fits inside a border which provides edge firmness to the foundation.

Description

BACKGROUND OF THE INVENTION [0001]This invention relates generally to bedding, and more particularly to a nestably stackable bedding foundation.[0002]Bedding foundations or so-called box spring assemblies generally include spaced border wires between which coil or bent wire spring modules are located. As thus manufactured, these box spring assemblies are bulky and shipping them to the manufacturer for application of padding and covering thereto is costly because of space requirements. To reduce the space requirements, it is customary to compress the assemblies to reduce their individual thicknesses and to tie them in their compressed state. This involves using presses and ties which are expensive, and the extra operations of pressing and tying the assemblies also adds to their manufacturing cost. At the delivery end, the manufacturer must cut and discard the ties before applying the covering. These additional material and handling expenses increase the end cost of box spring assembl...

AI Technical Summary

Benefits of technology

[0008]The longitudinal voids between the peaks of the support wires are of a greater dimension than the valleys of the support wires. This configuration enables one bedding foundation assembly of this invention to be nestedly stacked atop a second assembly since the support wire valleys of the first assembly fit into the voids between the peaks of the support wires of the second assembly. Such a nested and stacked arrangement results in a total height dimension which is less than the sum of the individual assembly height dimensions.

[0011]One advantage of this invention is that it provides a bedding foundation assembly having a cushioning layer, the components of which may be independently shipped, some of the component being tightly nested, compacted and shipped in a minimum of space to an assembly destination, thereby reducing the ultimate cost of the unit to the assembler.

[0012]Yet another advantage of this invention is avoiding the need for costly presses and ties necessary to compress a conventional box spring assembly for transportation.

[0013]A further advantage of this invention is that bedding foundation assemblies may be rapidly unloaded without the time consuming and labor intensive tasks of clipping and discarding the tie wires used to hold conventional box spring assemblies in a compressed state.

Problems solved by technology

As thus manufactured, these box spring assemblies are bulky and shipping them to the manufacturer for application of padding and covering thereto is costly because of space requirements.

This involves using presses and ties which are expensive, and the extra operations of pressing and tying the assemblies also adds to their manufacturing cost.

These additional material and handling expenses increase the end cost of box spring assemblies.

Toward that end, the spring modules commonly used in the box spring assemblies are relatively firm and provide little cushioning capability.

Some users find that such bedding foundations are too rigid for their liking; they would prefer a softer bedding foundation or box spring.
