  • 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: 9918558
    Abstract: A foam mattress is provided having a body facing surface comprising a first foam layer on a first spring layer formed of a plurality of individual pocketed spring coils. A second foam layer formed of a reticulated foam supports the first spring layer. The foam mattress further having a bottom layer of conventional foam. The foam mattress is surrounded by a foam casing that has at least one vent formed in the casing. The first spring layer causes air to flow from the second foam layer through the vents.

  • Publication number: 20160331150
    Abstract: A foam mattress is provided having a body facing surface comprising a viscoelastic foam layer. The body facing surface further comprises a recess or cavity into which a layer including a core of springs may be provided. The foam mattress further having a layer of open cell foam beneath the viscoelastic foam layer. The open cell, or reticulated, foam layer provides increased breathability. Support for the mattress may further be provided by a bottom layer of conventional foam.
