An object is to provide a hygienic cushion that has an adequate thickness to provide the repulsive force of or above a specified level and the body-holding property, is light in weight, has excellent air permeability and is washable with water. The core material for cushion 1 comprising the three-dimensional net-like structure, which is comprised of a polyethylene thermoplastic resin, a polyester thermoplastic elastomer or a mixture of a polyethylene thermoplastic resin and a polyethylene thermoplastic elastomer. The three-dimensional net-like structure has a first layer that includes a thermoplastic resin and a second layer that is stacked on a single surface or both surfaces of the first layer and includes a thermoplastic resin different from the thermoplastic resin of the first layer. The three dimensional net-like structure has an impact resilience of not lower than 13 cm, a hysteresis loss of not higher than 34% and not lower than 13%, and a thermal expansion rate of 0 to 8% in the longitudinal direction before and after a hot-air drying test that is performed at a temperature of 90 C. for 30 minutes with regard to the polyethylene thermoplastic resin, that is performed at a temperature of 130 C. for 30 minutes with regard to the polyester thermoplastic elastomer and that is performed at a temperature of 90 C. for 30 minutes with regard to the mixture of the polyethylene thermoplastic resin and the polyethylene thermoplastic elastomer.

A mattress system with at least two inflatable bladders located within a tub compartment of a foam encasement is enclosed. The bladders are surrounded on all sides by foam layers and the bladders are inflated and deflated by a control unit. The control unit is positioned within the tub compartment near the foot of the mattress and centered between the two bladder assemblies. The control unit is adhered to the foam encasement.

Long cut cellulose acetate staple fibers having cut lengths of 55 mm or greater can be used to readily form fiber blends with silk fibers. Additionally, the long cut cellulose acetate fibers may be used to form fill materials for filled articles, which can be produced from the fiber blends or formed entirely from the long cut cellulose acetate fibers. Due to their unique properties, the long cut cellulose acetate fibers may partially or entirely replace silk fibers in various applications.

The present disclosure provides an inflatable pad, the inflatable pad comprising: a top sheet; a bottom sheet connected to the top sheet to jointly define an inflatable chamber; an air valve; and at least one thermal insulation layer, the thermal insulation layer being an integral-piece batting-type sheet material, the thermal insulation layer being arranged in the inflatable chamber and welded to the top sheet and/or the bottom sheet along one or more welding regions. The inflatable pad according to the present disclosure facilitates mass production, has a good thermal insulation performance, and can also reduce noises when a user turns over, thereby improving comfort during use.

Organic fibers and inorganic fibers, used as materials, are mixed, thereby forming a web 18. Inter-fiber bonding is then performed on the web, forming a non-woven fabric web. The non-woven fabric web is cut, providing a web piece 18a shaped like a seat pad 30. The web piece is set in a metal mold and then compressed in the metal mold. Next, the metal mold is heated, thereby heating the organic fibers of the web piece, at surface, thereby welding the organic fibers together and molding a seat pad. The seat pad is covered with a trim cover, producing a cushion. The organic fibers are used in mixing ratio of 50% by weight or more, and the inorganic fibers are used in mixing ratio of 50% by weight or less. The organic fibers are made of simple high-molecular substance such as polyethylene fibers.
