<p>A box spring assembly has an array of vertical springs attached to a horizontal foundation and supporting a deck or platform for receiving a bedding load, i.e. a mattress and its occupant(s). The assembly has a plurality of deck elements each formed from a single length of wire with an elongate central section terminating in curved sections extending at least in some elements into spring legs. The deck elements are arranged in parallel lengthwise rows with adjacent elements of each row having aligned central sections. Adjacent curved sections are secured to each other and to adjacent rows by transverse helical connecting elements. The central sections of the spring elements and the transverse helical connecting elements together form the deck for receiving the bedding load. This deck is supported by the spring legs which are secured at their lower ends to the foundation.</p> |
