Mattress assemblies including fiber panels generally include bicomponent fibers including optically active particles within a core thereof. The bicomponent fibers can be treated with a fire retardant or untreated and blended with fire retardant fibers. The bicomponent fibers are configured to transform radiant body heat of an end user.

A wool mattress set includes a receiving mattress including a wool filling enclosed in a first envelope, combined with a base mattress comprising a foam filling enclosed in a second envelope. The wool filling of the receiving mattress includes a stack of one or more superposed wool mat layers, essentially devoid of wool flakes, and the receiving mattress is laid on the base mattress, the receiving mattress and the base mattress being independent and separable from each other. The foam filling of the base mattress, whose density is at least 35 kg/m.sup.3, can include in particular a material originating from foam recycling.

A modular sleep apparatus that enables customization of a conventional mattress. The modular sleep apparatus includes a customizable mattress pad casing having pockets into which various inserts can be placed. The more the number of pockets, the greater customization the mattress pad allows. The inserts themselves can be of varying thickness, firmness, and material. The inserts can also be placed directly over a conventional mattress and held in place with a fitted sheet. The inserts can also be placed directly into pockets or envelopes in the top layer of a mattress. The mattress pad casing can be pre-assembled with inserts.

A method of manufacturing a mattress that comprises forming a mattress inner core; forming a non-quilted mattress cover; and attaching the non-quilted mattress cover to the inner core without sewing. The non-quilted mattress cover may be formed of a laminate including a polymeric non-woven fabric that may be embossed and cut to include a cover top panel and a plurality of cover side panels that are unitary with and extend outward from the cover top panel. The step of attaching the non-quilted mattress cover to the inner core without sewing includes orthogonally orienting the cover side panels relative to the cover top panel and fusing portions of adjoining surfaces of adjacent cover side panels to each other to form a coffin, inserting the mattress inner core into the coffin, folding non-fused portions of the adjoining surface of the adjacent cover side panels over the mattress inner core, and bonding a bottom panel to the non-fused portions of the cover side panels and the mattress inner core.

A person support for supporting a person includes a first layer and a resilient second layer. The first layer has a surface topography with a first region with a curvature configured to correspond and generally conform, in an unloaded state, to the shape of a first portion of a person's body. The surface topography has a second region configured to correspond and generally conform, in an unloaded state, to the shape of a second portion of a person's body. The resilient second layer overlays the first layer and forms a person support surface.

The invention is an improved utility bedding product for use on beds or reclining chairs, particularly airplane seats. The inventive product is a multi-layered, lie-flat mattress pad that increases the comfort of passengers by providing a soft resting surface made of materials that permit the flow of air through the mattress pad. In preferred embodiments the mattress pad includes a pocket so the pad may be folded or rolled up and secured in a compact configuration for use as a pillow and for ease of transport.

A mattress core material includes a plurality of flat cushion bodies stacked in a thickness direction thereof, including at least a first cushion body which becomes an upper part when using the mattress core material; and a second cushion body which becomes a lower part when using the mattress core material, the first and second cushion bodies including a three-dimensional filaments-linked structure, the first and second cushion bodies each including a high-density upper surface layer having high filament density, formed in an upper surface layer region; a high-density lower surface layer having high filament density, formed in a lower surface layer region; and a low-density elastic layer formed between the high-density upper surface layer and the high-density lower surface layer, the low-density elastic layer being lower in filament density than each high-density surface layer, a intermediate position in the thickness direction of the mattress core material in which the first and second cushion bodies are stacked as upper and lower parts in the thickness direction, respectively, the high-density intermediate layer having a function of distributing a vertically applied compressive stress, along a curvature of an interface between the first and second cushion bodies in the high-density intermediate layer.

Disclosed is a support article containing a first non-woven layer and a second non-woven layer. The first non-woven layer contains a blend of fibers of about 15-70% by weight fire resistant (FR) rayon fibers, 10-30% by weight hollow conjugated siliconized fibers, and 20-40% by weight binder fibers. The second non-woven layer contains a blend of FR rayon fibers, hollow conjugated siliconized fibers, and binder fibers. The amount of FR rayon fiber is within 15 percentage points of the weight percentage of FR rayon fiber in the first non- woven layer. The lower surface of the first non-woven layer is adhered to the upper surface of the second non-woven layer. The density of the first non-woven layer is at least 10% less than the density of the second non-woven layer.

With regard to a care bed provided with a three-dimensional net-like structure made of a thermoplastic resin, an object is to smoothly bend the three-dimensional net-like structure in multiple stages in response to a complicated motion of a bed main body or a user's specific motion. A three-dimensional net-like structure 101 includes a first three-dimensional sparse/dense structure 1 provided as an alternately layered configuration of structural units 1a.sub.1 to 1a.sub.9 that are sparse in an extrusion direction Y and structural units 1b.sub.1 to 1b.sub.8 that are dense in the extrusion direction Y. In this first three-dimensional sparse/dense structure 1, a bulk density .sub.1 of the sparse structural units 1a.sub.1 to 1a.sub.9 is 0.01 to 0.08 g/cm.sup.3 and a bulk density .sub.2 of the dense structural units 1b.sub.1 to 1b.sub.8 is 0.03 to 0.10 g/cm.sup.3. A ratio .sub.2/.sub.1 of the bulk density of the dense structural units 1b.sub.1 to 1b.sub.8 to the bulk density of the sparse structural units 1a.sub.1 to 1a.sub.9 is 1.01 to 5. A length A.sub.1 of the sparse structural units 1a.sub.1 to 1a.sub.9 is 1 to 50 cm, and a length A.sub.2 of the dense structural units 1b.sub.1 to 1b.sub.8 is 3 to 60 cm. A ratio A.sub.2/A.sub.1 of the length of the dense structural units 1b.sub.1 to 1b.sub.8 to the length of the sparse structural units 1a.sub.1 to 1a.sub.9 is 0.1 to 10.
