Mattress assemblies are provided that include a mattress, a mattress overlay, and a mattress cover that is comprised of a first cover and a second cover. The first cover includes a top panel, a bottom panel, and a continuous side panel that collectively define a cavity and enclose the mattress. The mattress overlay is positioned atop the mattress and the first mattress cover. The second cover, which defines a perimeter, is positioned over and is dimensionally-sized to cover the mattress overlay and at least the top panel of the first cover. The second cover can then be connected to the first cover by a fastener that extends along the perimeter of the second cover.

The invention relates to formulations of aqueous dispersion adhesives based on aqueous polyurethane or polyurethane-urea dispersions, and to the use of the adhesive formulations for the adhesive bonding of foam substrates by the spray coagulation process. The dispersion comprises as disperse phase at least one polymer which after drying is semicrystalline or crystalline and has a melting temperature in the range from 30 to 80° C. and an enthalpy of fusion of ≥35 J/g. The formulation comprises at least one plasticizer and optionally at least one tackifier resin.

Hybrid coil and air chamber assemblies for cushioning supports generally include pressurized air chambers that are positioned intermediate strings of pocketed coils. In this manner, the coils and air chambers can move independently but can be made to cooperate to provide firmness control, contouring and/or support of a user thereof. Air pressure within the air chambers can be independently adjusted to manipulate firmness and/or contour properties in specific zones defined by the presence and location of the air chambers, e.g., pressure of the air chambers corresponding to the lumbar region can be adjusted to eliminate high pressure points. Still further, the pressure within the air chambers can be automatically adjusted to different applied loads as a function of movement. Also disclose are processes for adjusting a mattress including the hybrid coil and air assemblies.

A mattress assembly includes a chassis having top and bottom walls and first and second sidewalls that each extend from the top wall to the bottom wall. Inner surfaces of the walls and the sidewalls define an interior cavity. The top and bottom walls each include a first section that is connected to the first sidewall and a second section that is connected to the second sidewall such that the first sections are pivotable relative to the first sidewall and the second sections are pivotable relative to the second sidewall. The first section of the top wall is pivotable relative to the second section of the top wall and the first section of the bottom wall is pivotable relative to the second section of the bottom wall. A spring assembly is configured to be positioned within the interior cavity.

The present invention is a spring unit for a mattress comprising first and second pocket springs. Each of the first and second pocket springs comprise a coil pocket comprising a pocket and a coil spring disposed in the pocket and a cushion pocket comprising a pocket and a first resilient member disposed in the pocket of the cushion pocket. Each cushion pocket is engaged with and acting only upon the corresponding coil pocket. Substantially the entire side of the pocket of the coil pocket of the first pocket spring is engaged with substantially the entire side of the pocket of the coil pocket of the second pocket spring. Each cushion pocket is free standing and not connected with each other thereby creating a pumping action upon depression of the first pocket spring and/or the second pocket spring that produces circulation of air within the mattress.

A mattress wherein a plurality of independent yarn based fire barrier fabrics encases a plurality of distinct and unattached interior core structures. The plurality of interior core structures include at least a detached and internally flippable upper comfort layer assembly with a plurality of non-homogeneous foams or filling materials encased in a yarn-based fire barrier fabric and a lower, interiorly disposed support core structure with resilient filling materials encased in a yarn-based fire barrier fabric and a fabric cover. The detachable and internally flippable upper comfort layer assembly may be contained in a user accessible compartment that is fashioned into an outer cover assembly.

A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit.
