  • Patent number: 10213029
    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.

  • Patent number: 8375493
    Abstract: A one piece foam mattress core or innerspring encasement is a single contiguous piece of foam having a mattress core or base and four perimeter side supports and which fits with a mattress core or innerspring to provide an integrated mattress construction. The mattress core or base of the encasement is positioned below the mattress core or innerspring proximate to or against a bottom surface. The mattress core or base and the perimeter side supports are connected along fold lines or grooves in the single piece of foam so that the perimeter side walls can be folded to vertical positions about a perimeter of the mattress core or innerspring. The single piece of foam of the encasement is producible in different sizes to fit with different size mattress cores or innersprings.
