A down-fill pillow with a core formed from down feather sheet material pieces used in the fabrication of down insulated products. The size and shape of the pieces do not exceed predetermined sizes. The pieces may have a variety of shapes, such as in block or strip form or of irregular size if formed from trimmings of down sheet material in which is cut patterns for use in the fabrication of insulated articles. The down feather sheet pieces are placed in an envelope formed from one or more down feather sheets and the pieces entangle with one another due to their captive retention in the pillow envelope which restrains the pieces in close contact with one another and limited movement. When the head of a user person is rested on the down-fill pillow, it causes the mixture to compress and mold about the head while remaining entangled and recovering its loft when the head is removed. The method of forming the pillow core by the use of down feather sheet material pieces is also described.

A cushioning material includes fibers that define a fiber network and a foam material suspended within the fiber network.

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 down-fill pillow structure is formed by a fabric pouch in which is captively retained in close fit therein, one or more down feather sheet of predetermined density and substantially even thickness in which the down feathers are bound together by a binding agent. The down feather sheet has a memory which exhibits rebounding properties. A shaped core body may be inserted in the fabric pouch and encapsulated by the down feather sheet or sheet portions. The down-fill pillow may also be constructed as an ergonomic or non-allergenic pillow.

A support material having an hourglass shape reduces the cost of manufacturing as well as increasing comfort and air circulation. The support material includes a primary end having a primary diameter located opposite a secondary end having a secondary diameter. A substantially central portion of the support material has a tertiary diameter being a size less than the primary and secondary diameters. Additional improvements include an improved outer wall surface of the support material having at least one recess. The at least one recess can retain a substance such as a cooling gel.

A pillow includes a first pillow cushion consisting essentially of a gelatinous elastomer that is sized and configured to support a head and neck of a person using the pillow cushion and a second pillow cushion coupled thereto. The pillow cushion has deformable wall members located and configured to define voids therebetween such that the deformable wall members may be displaced into adjacent voids upon deformation of the deformable wall members. The deformable wall members are configured to buckle when a pressure applied to a cushioning surface of the first pillow cushion, in a direction perpendicular to a first major surface, exceeds a threshold pressure level. A pillow cover covers the first pillow cushion and the second pillow cushion. A method of fabricating a pillow includes enclosing such first and second pillow cushions in a pillow cover.
