  • Patent number: 8938824
    Abstract: Embodiments of the invention provide covers for bed components, such as mattresses and/or box-springs, which limit bed bug access to the bed component. According to one embodiment, a cover for a bed component may include an opening that provides access to an interior of the cover and through which a bed component (e.g., a mattress or box-spring) may be inserted, a zipper coupled along the opening, a zipper mechanism slidable along the zipper to couple opposing teeth of the zipper to allow the opening to be zipped closed to enclose the bed component within the cover, a first flap foldable and securable over a distal end of the zipper, a second flap foldable and securable over the first flap, and a barrier material disposed between the second flap and the zipper for applying pressure to the zipper to minimize a gap between the zipper and the first flap.

  • Publication number: 20130104311
    Abstract: In one embodiment, a mattress comprises a core and a cushion layer positioned above the core. A fibrous air spacer layer is positioned above the cushion layer, and a layer of visco-elastic foam is positioned above the fibrous layer. This permits the fibrous layer to be sandwiched between the cushion layer and the layer of visco-elastic material.

  • Publication number: 20110173757
    Abstract: A cushion may be constructed of a spacer material having a top layer, a bottom layer and a plurality of loosely arranged spacer elements that extend between the top and bottom layers so as to maintain the top layer and the bottom layer spaced apart from each other. An elastomeric gel material is incorporated into the top layer and/or the bottom layer. The gel material may also extend into at least a portion of the spacer elements.

  • Patent number: 7124652
    Abstract: A method for selecting a sleep system comprises positioning a person on a mattress in a lying position. One of the person's arms extends generally perpendicular to the person's torso. A first pillow is positioned underneath the person's head, and a force is applied to the person's arm in a direction generally toward the person's feet. An amount of resistive force supplied by the person's arm is estimated and used to determine whether the proper combination of mattress and pillow is achieved.
