A housing defines a housing interior. An air pump is within the housing interior. A first set of dampers supports the air pump within the housing. The first set of dampers at least partially isolates vibration of the air pump from the housing. A second set of dampers is configured to at least partially isolate vibration of the air pump from the housing. The second set of dampers arranged in series with the first set of dampers.

Various aspects of the present disclosure are directed to an apparatus and/or method involving respective sets of interleaved pressure cells, which operate to inflate and deflate independently of one another. The pressure cells further provide shear relief by deflecting along a direction of movement, such as along a shear direction of an upper surface coupled to the pressure cells. Such deflection may, for example, be implemented with elongated pressure cells and along a direction that is perpendicular to a length thereof. Shear relief in this regard may be facilitated by undercut regions of the respective pressure cells, at which location the pressure cells are coupled to an underlying surface and which is smaller in dimension relative to an overlying portion of the pressure cell.

A support platform supports a mattress. The support platform includes legs. Force sensors are coupled to the legs or to the support platform. The force sensors are configured to sense a force applied to each leg or support platform. A controller is configured to receive at least one force stream from at least one of the force sensors. The at least one force stream represents a force sensed by the force sensor. The controller is configured to, in responses to receiving the at least one force stream, determine a sleep parameter from the following group of sleep parameters: bed presence, weight, heart rate, respiration rate, and motions. The controller is configured to output at least one or more of those parameters to an end user.

A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.

An inflatable cushion comprises an inflatable cushion body. The inflatable cushion body comprises a first region and a second region formed by pressing an upper and a lower fabric layers; the first region and the second region are adjacent; a cavity is arranged in the first region; a sponge is arranged in the cavity; the inflatable cushion body is provided with an air guide part for inflating and deflating the cavity; the second region is evenly provided with transverse sealing lines; the transverse sealing lines separate the second region into mutually communicated inflating cavities; and the second region is provided with a first inflating port for inflation and deflation. By arranging the first region and the second region, the sponge is arranged in the first region and the inflating cavities are arranged in the second region.

Bladder pressure readings of bladder pressure inside an air bladder of a mattress are received for a particular time. Barometric pressure readings of barometric pressure in an ambient environment outside the mattress are received for the particular time. The bladder pressure and the barometric pressure readings are used as input to an ambient temperature classifier. Output from the ambient temperature classifier is received as an ambient temperature value for the particular time

An air supply device comprises an enclosure, a pump and a flow path switching unit. The flow path switching unit includes a pedestal part, a rotating part having an enclosure interior space communication portion and a groove portion, and a drive unit. The enclosure includes an air supply port, an air discharge port, and at least one object connection port. The pedestal part includes at least one first hole that is communicated to the at least one object connection port, and a second hole that is communicated to the air discharge port. The enclosure interior space communication portion is communicated to the air supply port through an interior space of the enclosure. The groove portion is separated from the enclosure interior space communication portion.
