MODIFIED FOAM LAYER AND WATERBASE PILLOW

摘要

A bed pillow with a water-bag support base advantageously includes a compressible foam layer above the water-bag base. The foam layer includes an upper portion of a memory foam and a lower density polyurethane foam therebelow. The low density polyurethane foam includes a convoluted base and vertically extending air vent channels are provided throughout at least a central portion of the pillow. With this arrangement improved air flow is provided. The air vent channels also improve localized compressibility whereby the response characteristics of the water-bag base support are maintained and not greatly dissipated.
