A method for making a bed having a mattress is disclosed. The method includes permanently attaching a mattress assembly to the mattress, removably attaching a sheet assembly to the mattress assembly, the sheet assembly including a first sheet member, which includes a fluid barrier layer, and a second sheet member, and blocking fluid using the fluid barrier layer from moving from the sheet assembly to the mattress assembly when the sheet assembly is removably attached to the mattress assembly.

A mattress cover may include a top cover portion, a bottom cover portion, and a border panel cover portion positioned to extend around a perimeter of a mattress. The mattress cover may include a closure element positioned to enable opening of the cover to access an interior region of the cover. The mattress cover includes an internal flange element positioned in the interior region. A mattress may include the cover, and the flange element may be connected to one or more internal mattress elements, such as springs or foam. A method of making a mattress may include positioning internal mattress elements in the interior region, attaching the internal flange element to at least one of internal mattress elements, and closing the mattress cover with a closure element such as a zipper. The closure element may be positioned on a bottom side of the cover.

A sleep system includes a ticking for a mattress, a bed cover, and a pillow cover. The ticking for a mattress is made of a first material. The ticking and the mattress together have a first set of temperature regulating performance-based properties associated therewith. The bed cover is made of the first material or of a second material having substantially the same temperature regulating performance-based properties as the first set of temperature regulating performance-based properties. The pillow cover is made of the first material, the second material, or of a third material having substantially the same temperature regulating performance-based properties as the first or second set of temperature regulating performance-based properties.

A polymeric material mixture comprising a fluorine-containing polymer, a siloxane polymer, and at least two polymer processing additives (PPA), wherein the at least two polymer processing additives have different chemistries. For example, there can be a flexible coextruded pipe for providing a protective housing for cables, fluids, sludge or solids, the pipe comprising a pair of telescopically related inner and outer layers, where said inner layer is lubricated with the polymeric material mixture.

Multilayered cushions and positioners include a plurality of compressible layers, at least of which may include a breathable chamber that holds compressible beads. The compressible beads may flow until an object is placed thereon or until the compressible layer is placed against a surface. A compressive force exerted by the object or the surface on the beads may compress them, causing the beads to conform to a shape of the object or surface and increasing a coefficient of friction of the beads, which may hold the beads in position and increase a rigidity of the cushion or positioner at the location thereof that receives the object or surface. An intermediate element, such as a pressurizable element, may be positioned between compressible layers to prevent forces exerted one of the compressible layers from being communicated directly to the other compressible layer.

A mattress includes a layer including a first surface and a second surface arranged opposite to the first surface. The layer defines a plurality of slits extending from the first surface to the second surface and arranged in a plurality of rows extending in a longitudinal direction. The slits in each row are arrayed linearly in the longitudinal direction and are disposed spaced apart from each other. The rows of the slits restrict a compression of the layer to an area under loading and prevent the surrounding portion of the layer from being pulled towards the area under loading.

A mattress assembly includes a cover, a spring pack positioned within the cover, and an inner core positioned within the cover. The inner core includes opposite first and second portions. The first portion has a firmness that is different than a firmness of the second portion. The inner core is configured to be moved between a first configuration in which the first portion directly engages the spring pack and a second configuration in which the second portion directly engages the spring pack to alter a firmness of a sleep surface of the mattress. Methods of use are disclosed.

A system can include a zipper that connects a mattress to a bed foundation. For example, the zipper can extend from a head end to a foot end of an adjustable foundation. For another example, a zipper can connect to a mattress along a seam of the mattress and/or to a foundation along a seam of a foundation. For another example, a first zipper can connect the mattress core to a second zipper and the second zipper can connect a foundation to the first zipper. For another example, first and second zippers can be substantially vertically aligned.

A mattress including a stretchable flame-retardant textile cap incorporating a top panel of flame retardant material operatively connected to a stitch-bonded flame retardant textile skirting with machine direction stretch and recovery properties disposed over a resilient mattress core to provided flame barrier protection to the mattress core.

A mattress or mattress topper includes a cushioning element having an elastomeric material forming intersecting buckling walls that define hollow columns, and a knitted fabric disposed over the cushioning element and configured to move independently of the buckling walls. The elastomeric material includes an elastomeric polymer and a plasticizer. The knitted fabric includes a first layer of stretchable material; a second layer of stretchable material; and a layer of stretchable fill material between the first layer of stretchable material and the second layer of stretchable material. The first layer of stretchable material is knitted together with the second layer of stretchable material as a unitary sheet of fabric including the layer of stretchable fill material. A method of forming a mattress or mattress topper includes disposing a knitted fabric over a cushioning element comprising intersecting buckling walls and configuring the knitted fabric to move independently of the buckling walls.
