Abstract: A mattress assembly includes a mattress base and a mattress top having first and second major surfaces extending to a peripheral edge. Slidable fastener means disposed between the mattress top and the mattress base removably and rotatably attaches the mattress top to the mattress base. In an associated method for moving a body depression in a mattress, the mattress top is attached to the base with at least one zipper having a first side and a second side. Opening the zipper permits removal and rotation of the mattress top relative to the mattress base to move the body depression to a different position. Closing the zipper reattaches the mattress top to the mattress base.

Abstract: A hybrid watermattress has a compressible sidewall, a water fillable bladder, and a cover to envelope the bladder and the sidewall. The sidewall extends laterally and peripherally of the bladder, and in an uncompressed state, has a generally concave cross section that is complementary to the lateral panels of the bladder.

Abstract: A mattress construction includes a watermattress bladder or inner spring mattress subassembly which is enclosed in a quilted mattress cover. This cover typically includes an outer fabric, a backing and an inner fabric which are quilted together. The outer fabric is colored and typically provided with a pattern or indicia. The fabric itself consists of a loose weave of threads providing openings or interstices in the fabric. The backing, typically formed of foam or fiber, is provided with pigments which are visible through the interstices of the fabric and provide a background color for the color in the fabric. In this manner, the pigments in the backing material enhance the distinct images of the indicia and add to the depth and richness of the mattress color. This provides the mattress cover with substantially colorfast characteristics increasing its chroma and color quality to provide an attractive, long lasting, appealing appearance.

Abstract: A mattress includes a resilient member having an original size and shape and properties for compressing under the weight of a person lying on the mattress to a second size and shape. A mattress cover enveloping the resilient member includes a top panel having a memory fabric with particular stretch characteristics for expanding to the second size and shape when the person is lying on the mattress, and particular retention characteristics for returning to the original size and shape when the person is removed from the mattress. The memory fabric is especially desirable in avoiding the "hammock effect" in hybrid watermattress constructions.

Abstract: A method of making textured foam coatings and materials is disclosed. A mixture of a curable frothed elastomeric emulsion composition and 20 pounds or less of thermally expandable beads to each 100 pounds of elastomeric composition is applied to a foam substrate and heated. During heating the plastic beads expand to produce a textured pebble-like coated elastomeric article.

Abstract: A textured building material, suited for use as an acoustical wall and ceiling covering, comprising a cellular urethane foam substrate and an elastomeric coating and a method for its production is disclosed. The building material is flexible and damage resistant, which makes it especially useful in mobile vehicles and homes. The process consists of applying a foamed elastomeric resin emulsion onto a urethane substrate to a desired thickness; drying the coated substrate thus formed; and thereafter crushing the dried elastomeric coated substrate to form a composite textured material.
