A mattress according to the invention is formed from a plurality of layers stacked in a thickness direction thereof, and includes a tactile layer that is positioned on an upper side in use, and a cushion layer that is positioned on a lower side in use. The tactile layer and the cushion layer each contain an elastic body constituted of a filament three-dimensional assembly. The elastic body contained in the cushion layer has a larger resiliency than that of the elastic body contained in the tactile layer, and is 100 N or more and 200 N or less. The elastic body contained in the tactile layer has a resiliency of 10 N or more and 80 N or less. The tactile layer shows a constant sinking displacement regardless of load.

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 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; and a second cushion body which becomes a lower part, the first and second cushion bodies including a three-dimensional filaments-linked structure, each including a high-density upper surface layer having high filament density; a high-density lower surface layer having high filament density; and a low-density elastic layer, a high-density intermediate layer being formed in an 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.

A three dimensional polymeric fiber matrix layer for use in a bedding product such as a mattress is disclosed. The three dimensional polymeric fiber matrix layer generally includes a plurality of randomly oriented polylactide (PLA) fibers bonded at coupling points between adjacent PLA fibers and having a free volume per unit area of the layer.

A pre-conditioned three dimensionally polymeric fiber matrix layer for use in a bedding product such as a mattress is disclosed. The pre-conditioned three dimensionally polymeric fiber matrix layer generally includes an extruded three dimensional polymeric fibrous layer and a foam material, e.g., polyurethane, latex or the like, disposed within the fibrous layer and occupying at least a portion of the free volume in the layer, wherein a portion of the coupling points and the randomly oriented polymer fibers are broken so as to change a mechanical property of the pre-conditioned three dimensionally polymeric fiber matrix layer relative to the three dimensionally polymeric fiber matrix layer without pre-conditioning.

A three dimensional polymeric fiber matrix layer including a phase change material coated thereon for use in a bedding product such as a mattress is disclosed. The phase change material is selected to provide improved cooling properties, which along with the free volume provided by the three dimensional polymeric fiber matrix markedly improves temperature management when used in a bedding product.

The present invention provides a thermal insulation filling material and preparation method thereof and a thermal insulation product, and pertains to the field of thermal insulation filling materials. The thermal insulation filling material of the present invention includes: a bulk fibre; and a spherical fibre assembly, where a water-repellent layer is formed on a surface of the bulk fibre and of the spherical fibre assembly, and a weight ratio of the bulk fibre to the spherical fibre assembly is between about 30:70 and about 70:30. The thermal insulation filling material is good in wash durability, and has comprehensive performance such as better blowable processability, quick-drying property, compression-resilience property, and thermal insulation property, etc. The method for preparing the thermal insulation filling material includes: adding a water-repellent agent in the process of gas-flow mixing the bulk fibre and the spherical fibre assembly, and then heating to form a water-repellent layer on the surface of the bulk fibre and of the spherical fibre assembly.

A mattress containing a core section, a high loft non-woven layer at least partially covering a first side of the core section and containing a plurality of heat and flame resistant fibers, bulking fibers, and binder fibers, a ticking layer at least partially covering the high loft non-woven layer and containing a textile layer, a pattern coated layer. The pattern coated layer may be printed on the high loft non-woven layer, the ticking layer, or any layer between the high loft non-woven layer and the ticking layer. The pattern coated layer contains a blend of microencapsulated phase change material (PCM) and a binder, wherein the PCM is fully encapsulated by the binder.

A mattress is described, comprising an ergonomic layer made of foam material and a breathable layer made of three-dimensional polymeric material. The ergonomic layer and the breathable layer are mutually coupled. The breathable layer is individually wrapped in a casing made of a three-dimensional breathable fabric. The combination between the breathable layer and the respective casing, which is also manufactured with a three-dimensional breathable type of material, allows to obtain the maximum breathable characteristics for the mattress.
