Patent ID: 11547217

Abstract:
Disclosed is a mattress assembly having a spring or foam core structure and reduced-sized parts. Spaced along the mattress top and bottom border are a plurality of bands having through-openings. Border wire segments extend through the through-openings and are joined end-to-end by releasable connectors to form a continuous border wire providing edge support. Butterfly springs having tube-like bands for receiving the border wire segments prevent sagging. In spring mattresses, the bands, which may be rings or a similar type part, are carried at the top and bottom of the outer springs. In foam mattresses, the bands are formed by a plurality of loops formed in a continuous folded strip fixed by adhesive or other means to the mattress border walls. Two such mattresses may be joined together by interweaving a flexible cord through the bands of adjoining mattresses. The mattress assembly is completed by encasing in an outer cover.
