Abstract
The present application provides a cushion having a core layer and a quilt support/comfort layer. The core layer may comprise innersprings, foams, air cells, or combinations thereof. The support/comfort layer comprises a sleep layer that simulates a conventional quilted fabric layer. The sleep layer includes a thick, comfort fabric and a backing fabric, which backing fabric may be the same as the thick, comfort fabric. The sleep layer is formed by coupling the thick, comfort fabric to the backing fabric to form a plurality of individual pockets in which micro spring coils are placed. The micro spring coils have less uncompressed height than conventional innerspring coils. The sleep layer coupling is formed by spot coupling without using a metal needle to stitch the layers together. In other words, the spot coupling may comprise an adhesive or weld.
