A topper placed on a bed or a mattress, for distributing a load, includes a top cover forming a top of the topper, an upper memory foam provided under the top cover, at least one cushioning member provided under the upper memory foam and configured to distribute a load transmitted through the upper memory foam, a lower memory foam provided under the cushioning member, as a component corresponding to the upper memory foam, and a bottom cover provided under the lower memory foam, manufactured as a component corresponding to the top cover, and configured to support the cushioning member.

A seat pad manufacturing method is provided. The method includes disposing a sheet member inside a foaming mold for shaping a seat pad, then injecting a foaming resin material into the foaming mold and foaming a resin foamed body through mold clamping, and demolding the resin foamed body in a state in which the sheet member is buried in the resin foamed body. Both end parts of the sheet member in the right-left direction and both end parts of the sheet member in the extending direction are each temporarily fastened to the surface of the mold through a fastener. The foaming resin material is injected into a space between the mold surface and the sheet member. A central part of the sheet member deforms into a shape curved in a convex shape as the sheet member is pressed upward through expansion of the foaming resin material.

Multilayered mattress assemblies include at least one elongated elastic wrap compressively looped about at least two layers of the mattress assembly to maintain the at least two layers in a fixed relationship relative to one another.

Consumer products such as pillows for bedding or furniture, sack-like furniture, toppers for car seats, office seats, or household seats, and pet mattresses, are constructed from an outer casing, such as a woven or knitted fabric or a quilted fabric which may include a cushioning layer and a plurality of cut pieces of vertically lapped nonwoven material. The outer casing may be sewn closed but preferably includes a zippered opening or other opening which can be selectively opened and closed to allow the consumer to add or subtract cut pieces of vertically lapped nonwoven material from the interior volume of the outer casing. A zippered inner layer may neatly hold all of the cut pieces of vertically lapped nonwoven material together while the outer casing is changed or cleaned.

A foam mattress in which a layer of latex or latex-like foam placed above a layer of memory foam is described. This construction of the mattress provides the contouring pressure relief that a visco-elastic foam provides with a top surface with quick recovery (a latex-like “bounce”) that prevents people from getting “stuck” in the visco-elastic foam and improves the springiness of the mattress. The mattress may also include straps and cinches to aid in transportation of the mattress. The mattress may also include removable covers that aid in keeping the mattress clean.

Mattress assemblies that provide user comfort and increased airflow generally include a viscoelastic thermally conductive infused polyurethane foam top layer; a composite comprising a bottom layer, a molded viscoelastic middle foam layer, and a perforated top viscoelastic foam layer, wherein the molded viscoelastic middle foam layer comprises a plurality of interconnected substantially parallelpipedal bodies, wherein each parallelpipedal body includes an opening extending from a bottom surface to a top surface and is separated from an adjacent parallelpipedal body by a V-shaped notch, and wherein the perforated top viscoelastic foam layer comprises a plurality of perforations extending from a bottom surface to a top surface thereof, wherein at least a portion of the perforations overlies the opening in the parallelpipedal bodies; and a base core layer, wherein the composite overlies the base core layer.

A shaped body including at least one section of a polyurethane foam. The shaped body includes a temperature-regulating device arranged in thermal contact with the at least one section of the polyurethane foam and a control device for the temperature-regulating device adapted to adjust the firmness of the at least one section of the polyurethane foam by alteration of temperature of the at least one section of the polyurethane foam this device being in “S” shape. The shaped body is used as a bed or mattress for promoting sleep in one application.
