A smart sleep system comprising a mattress including a plurality of pressure zones, each pressure zone separately adjustable for firmness, a sensor to sense a user's position on the mattress, a processing system to determine pressure for each of the plurality of pressure zones based on data from the sensor, and a controller to adjust one or more of the pressure zones based on the determination.

The present invention discloses a turning air mattress, a turning air cell, and a control method for a turning air mattress. With structural arrangements of an upper portion and a lower portion of the turning air cell as well as inflation and deflation control, the turning air cell having an upper portion that is wider and a lower portion that is narrower can further assist a patient in body turning, enabling the patient to easily achieve a sufficient body turning angle, further reducing the risk of likeliness to pressure sores caused by the structure of the air mattress pressing against the body of the patient.

A vacuum pump includes a hollow container that has a vacuum port and internal chamber walls. The vacuum port opens to an exterior of the container and the chamber walls define chambers that are in fluid communication with the vacuum port. There are flexible bladders disposed in the chambers. The flexible bladders include vents that open through the container to the exterior. A plunger in the container includes arms that extend into the chambers such that each of the flexible bladders is situated between one of the arms and one of the chamber walls. The plunger is moveable between a home position and an upstroke position to compress and deflate the flexible bladders via the vents and thereby change the volume of the flexible bladders. The change in the volume draws a vacuum through the vacuum port.

A mattress topper system, and a method of controlling the system, including an upper sheet and a lower sheet coupled together so as to define an interior volume divided into a plurality of zones, each of the zones having a plurality of cells of which adjacent cells are in fluid communication with one another inside the respective zones, and at least one air pump configured to regulate pressure in the cells of each respective zone such that the pressure in at least a first one of the zones is different from the pressure in at least a second one of the zones.

The present invention relates to the field of outdoor appliances, in particular to a compressed sponge self-inflating cushion. The self-inflating cushion of the present invention has a wide range of applications, and can be used both indoors and outdoors, and a sponge automatically absorbs air, so that automatic inflation is achieved. There is no complicated electronic circuit inside, so there is no need to worry about whether an inflatable cushion body cannot be inflated due to electric leakage or insufficient power supply. The surface of the sponge is provided with a plurality of parallel folding grooves for convenient folding and winding, and thus a user can conveniently wind up the inflatable cushion body.

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.

The present invention relates to a compactable mattress for use on a predetermined arrangement surface. The compactable mattress may include: a support layer and a comfort layer, arrangeable at the support layer. The support layer may be provided with a predetermined underside shape for shape adjustable arrangeability relative to the predetermined arrangement surface. The support layer may be provided with a predetermined topside shape for arranging thereof of the comfort layer. The support layer may be transformable between a state of use and a compacted state.

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.
