Benefits of technology

[0009] Embodiments of the invention are foam bedding products including viscoelastic foam having a high air flow value. Such products provide the support advantages of viscoelastic foam, but do not feel hot to the person sleeping on the products.
[0010] An embodiment of the present invention comprises a pillow having a foam core having sufficient firmness to provide effective support for a user and a hyper soft high air flow viscoelastic foam shell surrounding the core and having sufficient firmness to maintain an outer shape of a conventional pillow when supporting only a pillowcase or other bed coverings. The core may have any desired contoured shape.
[0011] Another embodiment comprises a method for making a bedding product. Both the core and the shell may be cut from blocks of appropriate foam. The shell is cut with a desired bedding product outer shape and in some cases with a cavity in a desired

Embodiment Construction

[0025] In this disclosure, the term “conventional pillow shape” refers to the outer shape of a conventional pillow comprising two rectangular pieces of ticking sewed together along their edges and filled with any conventional pillow filling, e.g. down, feathers, ground foam, polyester fiber, continuous foam, etc. Reference to the top, bottom, ends or side edges, and front and back edges of a pillow are with reference to a pillow positioned on a horizontal bed surface for its normal intended use. While specific dimensions may be given for various embodiments, it is apparent that pillow sizes are somewhat standardized into sizes such as standard, queen and king, based on bed sizes. For example standard sized pillows may have a length dimension of about 22 to 24 inches, a width of from about 13 to 16 inches and a thickness of from 3.5 to 6 inches. King-sized pillows may have the same width and thickness dimensions and have a length of from about 30 to 32 inches.

Abstract

Foam bedding products including viscoelastic foam having a high airflow value that do not feel hot to the person sleeping on the products. One product is a pillow having a contoured core having sufficient firmness to provide effective support for a user and a hyper soft viscoelastic foam shell surrounding the core having sufficient firmness to maintain the appearance of a conventional pillow when supporting only a pillowcase or other bed coverings. The core may be made of higher density viscoelastic foam or of a resilient foam. Another product may be a mattress topper with or without foam cores for body support carried within slabs of high airflow viscoelastic foam.
