DETAILED DESCRIPTION OF THE DRAWINGS

[0034]With reference to FIG. 1, there is illustrated a bedding product in the form of a single-sided mattress 10 incorporating this invention. This product or mattress 10 comprises a pocketed spring assembly 12 over the top of which there lay conventional padding or cushioning layers 14, 16 which may be foam, fiber, gel, a pocketed spring topper or any other suitable materials. Although two padding or cushioning layers 14, 16 are illustrated on top of the pocketed spring assembly 12, any number of padding or cushioning layers may be used, including a single padding or cushioning layer. The pocketed spring assembly 12 is mounted upon a base 18 and is completely enclosed within a covering material 20.

[0035]As shown in FIG. 1, fully assembled, the product 10 has a length “L” defined as the linear distance between opposed end surfaces 22 (only one being shown in FIG. 1). Similarly, the assembled product 10 has a width “W” defined as the linear distanc...

Abstract

A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel interior strings of individually pocketed coil springs. The interior strings of springs may extend from head-to-foot or side-to-side of the product. The pocketed spring assembly further comprises at least one perimeter string of springs. Each of the springs of each perimeter string of springs has rectangular convolutions to provide edge support to the product.

Description

TECHNICAL FIELD OF THE INVENTION[0001]This invention relates to bedding and seating products and, more particularly, to pocketed spring assemblies used in bedding and seating products, including mattresses and the method of manufacturing such pocketed spring assemblies.BACKGROUND OF THE INVENTION[0002]Pocketed spring cores or assemblies are commonly used in seating or bedding products. Such pocketed spring assemblies are commonly made of multiple strings or rows of individually pocketed springs. Adjacent strings of individually pocketed springs are joined together by gluing or otherwise attaching the fabric of the strings of springs to each other.[0003]Pocketed coil springs are often referred to as a Marshall construction in which each coil spring is encased within its own fabric sack or pocket. The sack or pocket is typically defined between two plies of a fabric strip connected together at intervals along transverse lines of attachment spaced along the strip. The two-ply fabric st...
