  • Institutional bedding with integral pillow and mattress
    Patent number: 6785923
    Abstract: A bedding arrangement is provided having a compressible foam mattress pad and compressible foam pillow pad integrated as a single bedding unit within a fluid resistant or impermeable cover whose seams are heat sealed together. Air ventilation through the cover and about the interior foam is permitted by a vent that restricts insect, article and fluid passage through the vent. By using foam of different densities and/or composition, optimum performance characteristics in terms of comfort and support can be obtained separately for the mattress portion and the pillow portion. By mounting two pillow pads within the cover, the bedding arrangement can be made reversible.
