  • Publication number: 20130269113
    Abstract: A mattress is disclosed comprising a flexible frame for bearing uniaxial compressive stress from a human body pressed onto the frame. The frame traverses the breadth and length of the mattress in evenly-spaced repeating patterns which defines hollow recesses filled with materials like silicone gel, memory foam, coils, and springs. The flexible frame in some embodiments, has a higher compressive strength than does the traditional material(s) filled the recesses defined by the frame. The indentation force deflection (IFD) rating varies slightly across small, repeating regions the surface of the mattress. These regions provide lumbar, thoracic, and pelvic support to a user. A user may move about on the mattress during the night to adjust the areas of the small regions pressing most firmly against the body, selectively adjusting both the position of the body and the pressure points of the mattress to maximize comfort.

  • Patent number: 8555440
    Abstract: An air mattress has a top chamber and a bottom chamber separated by a barrier. The patient rests on the top surface of the top chamber, which has a plurality of apertures discharging air through apertures that are not blocked by the patient. The top chamber is provided with temperature-controlled heated or cooled air at a regulated pressure. Heated or cooled air from the top chamber is delivered to an area substantially surrounding the patient. The bottom chamber has a bottom surface containing a plurality of apertures that remain closed due to the weight of the mattress and the patient when the pressure-regulated air is beneath a pre-selected value. When the air pressure is increased, the apertures at the bottom surface of the bottom chamber emit air, creating an air cushion underneath the air mattress that facilitates lateral movement of the mattress over a flat or irregular surface, such as from a hospital bed to a stretcher, or from a stretcher to an operating table.

  • Patent number: 8468621
    Abstract: A furniture product includes a folding mechanism that folds into a seat frame. The folding mechanism includes a rear section, a middle section, and a front section, with the rear and middle sections being received in a cavity in the back of the seat frame when the product is in a stowed, seating position. Upon receiving a user input, a position motor deploys the folding mechanism into a sleeping position. Upon achieving the sleeping position, an inflation switch is engaged. An air pump disposed in or near the furniture product is activated in response to engagement of the inflation switch. To return the product to a stowed, seating position, a user input causes the air pump to deflate the mattress and the position motor to fold the folding mechanism into the seat frame.
