  • Patent number: 9167909
    Abstract: A mattress core has front and rear ends that are spaced apart in a longitudinal direction and further has opposite sides that are spaced apart in a lateral direction. The core includes a firmer lower core section having a top surface that follows an undulating pattern. The undulating pattern is non-uniform and non-symmetric in the longitudinal direction, is uniform in the lateral direction, and includes at least one hill, at least one valley and at least one plateau. The core further includes a softer upper core section that overlies the lower core section. The upper core section has a bottom surface that follows the undulating pattern and contacts the lower core section's top surface to provide a common mating interface that follows the undulating pattern. The interface includes at least one hill, at least one valley and at least one plateau.

  • Patent number: 8990987
    Abstract: A layered cushion that may be fully disassembled for easy cleaning is disclosed herein. The sleep system is durable and fire retardant. The layered cushion may include a foam layer, a layer of void cells, and a cover. The foam permits fluids to move freely there through and contours to a user's body to maximize comfort and reduce interface pressure. The reticulated foam layer resists compression set and thermosetting. The layer of void cells also permits fluids to move freely there through and provide additional support to the user's body. The individual void cells of the void cell layer are perforated to allow the transmission of fluids there through. The cover couples the other layers together to form the layered cushion and prevents the layers from deteriorating. The cover is removable to permit cleaning each of the layers independently.

  • Publication number: 20130283538
    Abstract: Embodiments disclosed herein include mattress assemblies and components employing passageways for ventilation and airflow. A mattress may contain a mattress core to provide cushioning and support. For example, the mattress core may comprise an innerspring, air bladder(s), and/or foam layer(s). A mattress assembly may include a foam base and/or at least one foam side support member to at least partially surround a mattress core to provide cushioning and structure. The foam base and/or at least one foam side support member may include at least one passageway for facilitating diffusion and air exchange between an exterior environment and an interior space of the enclosure containing the mattress core. In this manner, as stagnant air and humidity developing in the mattress core may be avoided or reduced from the mattress core, which may otherwise cause unhealthy conditions or unpleasant odors for users.
