A patient support is provided. The patient support may include a plurality of inflatable members. The plurality of inflatable members may include a core including a resilient material. The patient support may be controlled with a first controller positioned within an envelope of the patient support. The patient support may include a detector to detect when an external controller is coupled to the patient support, the patient support being controlled by the second controller when the second controller is present.

An article of manufacture includes an inflatable body comprising a first core member cut from a single slab of core material and a second core member cut from the single slab of core material and coupled to the first core member.

A mattress and adjustable foundation selection system and process generally includes a mattress having a pressure sensor pad configured to detect localized pressure changes on a sleeping surface as a function of a subject lying on the mattress optionally while the comfort of said mattress is adjusted by means of one or more fluid filled chambers; an adjustable foundation adjustably supporting the mattress and configured to change the mattress from a planar configuration to a non-planar configuration; and a display for displaying a contour map associated with the localized pressure changes. The method includes positioning a subject in a sleeping position on a planar surface of a mattress operatively coupled to an adjustable foundation; displaying to the subject a contour map of localized pressure changes as a function of positioning the subject on the mattress planar surface; adjusting the adjustable foundation and changing the planar surface to a non-planar surface; and displaying to the subject a contour map of the localized pressure changes associated with the mattress non-planar surface.

An article of manufacture includes a first discrete inflatable body having a first core member cut from a single slab of core material and a first root portion, and further includes a second discrete inflatable body comprising a second core member cut from the single slab of core material and a second root portion. Each of the first and second core members includes a plurality of ribs, and the ribs extend laterally from the first and second root portions.

A fluid fillable cushioning device comprises an enclosure comprising a top wall and a bottom wall, a cavity defined by the enclosure, a threaded inlet in the enclosure connected to the cavity, the cavity further defined by the threaded inlet, and a fastening mechanism extending from the enclosure, the fastening mechanism configured to fasten the cushioning device to a seat. In operation, fluid, such as water, is filled in the cavity of the cushioning device, and in some cases foam is also included in the cavity, providing a water and/or foam cushion for a user sitting on the cushioning device. When used on seat of a bicycle, where the user's body interacts with the cushioning device with significant pressure for extended period of time, the cushioning device provides customizable cushioning which feels like an extension of the body, and is exceptionally comfortable.

A pneumatically adjustable bladder system (90) for use in a cushioned seat bottom (24) has one or two rear foam filled bladders (62, 64) for location under the ischial tuberosities of a seated occupant of the seat bottom, and one or more expansion chambers (14, 16) or front foam filled bladders (66, 68) for location under the thighs of the seated occupant. There are air passageways (70, 72, 74, 92) interconnecting the bladders with each other or with an expansion chamber. The system is air tight and the bladders are compressible under the weight of the seated occupant and are expandable when the weight is removed. The compression of a bladder causes air therewith in to be displaced through the air passageways to the expansion chambers or to the other bladders, which then expand. The compression of a bladder under the ischial tuberosities of the seated occupant and the expansion of the expansion chambers or of the other bladders under the thighs of the seated occupant cause the seated occupant to experience a correct level of immersion into the cushioned seat bottom which is desired for effective postural support and prevention of lower back pain.

What are described are shaped hot-cure flexible PU foam articles, preferably mattresses and/or cushions, wherein the hot-cure flexible polyurethane foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one compound of formula (1a) and at least one compound of formula (1b) and at least one blowing agent and at least one catalyst.

This disclosure describes, among other things, techniques for waking a user by changing the user's sleep environment. In one example, a method includes receiving, at a central controller of an air mattress system, at least one user alarm setting, generating, via the central controller, at least one instruction based on the received user alarm setting, and transmitting, from the central controller, the at least one instruction to a first component of the air mattress system to adjust a feature of the first component.

A mattress can include one or more layers of foam material, an adjustable air layer including an air bladder, and a valve. The valve can be fluidically connected to the air bladder and configured to regulate pressure of the air bladder in response to actuation. Some embodiments can include a foam material positioned inside the air bladder.

The methods and structures disclosed herein may be used to make sleep products having foam substrates and gel layers such as mattresses, mattress toppers and pillows. The gel layers may have cooling properties and may include phase change materials. The foam substrates may also be treated with phase change materials.
