An adjustable mattress is described herein. The adjustable mattress is comprised of one or more adjustable elements. The adjustable elements may, in some examples, be filled with air or other fluid in order to adjust the height and firmness of the adjustable mattress. The adjustable mattress may provide a user with assistance in rolling over or repositioning while using the adjustable mattress.

A sleeping pad with a fast-inflation and deflation air nozzle includes a sleeping pad body with an air nozzle. The air nozzle includes a base, an air channel and a sealing cover. The sealing cover is detachably and sealedly inserted into the air channel. The air channel is detachably and sealedly inserted into the base. A deflating gasket is arranged at a top of a support in the air channel. A bottom of the support is provided with an inflating gasket. A switch between an inflation mode and a deflation mode is realized through switching positions of a first baffle plate and a second baffle plate of a switch baffle plate.

Inflatable sleeping pad systems and methods are provided. An inflatable sleeping pad may include a central pad including a self-inflating foam, at least one inflatable side rail connected to at least one edge of the central pad, and a valve configured to pass air between an external environment and an interior of the inflatable sleeping pad. A system may include the inflatable sleeping pad and a storage bag configured to receive the inflatable sleeping bag when in a deflated configuration. The system may include a removable covering configured to cover at least a portion of the inflatable sleeping pad when in an inflated configuration.

An auto-inflating cushion structure includes an outer covering and an inner filling body. The inner filling body is accommodated in the outer covering and has a three-dimensional shape in a normal state. The outer covering is provided with an air valve unit. When not in use, the cushion can be compressed to become thin, thereby reducing the volume without occupying space. When in use, the external air flows into the outer covering, in cooperation with the expansion of the inner filling body, so that the interior of the cushion is automatically inflated. The cushion can serve as an auxiliary support for a user lying on his/her side. In particular, the storage is quite space-saving and the cushion is practical.

An adjustable mattress topper assembly disposed in a cover is disclosed. The topper assembly may have one or two inflatable multi-valve bladder assemblies filled with foam; the topper assembly may be disposed in a topper body of foam. A hand-trigger may be used to operate a valve and inflate and deflate the bladder assembly, which may be located below the lumbar of a supine user.

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 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.

A valve comprises a base, a cover and a sealing member. The base comprises a passage structure and a retaining member; the cover comprises a corresponding retaining member and at least one hole, and the cover is movably combined with the base and switchable between a first state and a second state relative to the base; a sealing member is disposed between the passage structure and the cover. In the first state, the cover closes the passage structure by the sealing member to prevent the flow of the fluid between the cover and the base; in the second state, at least one fluid channel is formed between the cover and the passage structure and is in communication with the at least one hole, and the retaining member and the corresponding retaining member prevent the cover from being separated from the base when the cover moves relative to the base.

A self-inflating stowable bed. The bed includes one or more self-inflating chambers, with each of the self-inflating chambers having one or more polyurethane foam sections therein, with the chamber defined between a first air impervious layer and a second air impervious layer. The self-inflating bed may be evacuated by a household or shop vacuum, and then sealed, rolled or folded, and easily stored or shipped. The polyurethane foam sections may be provided with different members having different indentation force deflection specifications suitable for bed portions and edge of bed portions.

The present invention relates to a valve for inflatable apparatuses. The valve comprises a housing, a sealing disc and a handle. The handle is coupled to the sealing disc, and is adapted for rotating the sealing disc within the housing.
