A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.

An air distribution unit for environmentally controlled furniture, such as a bed. In representative embodiments, the air distribution unit includes a fan enclosure for accommodating a fan, with a fan enclosure inlet upstream of the fan and a fan enclosure outlet downstream of the fan, the fan enclosure including an air-flow guidance member positioned in the fan enclosure, which defines at least in part, an air-flow path between the fan enclosure inlet and the fan enclosure outlet, wherein an inner surface of the air-flow guidance member, adjacent to the air-flow path, is at least partially sound-absorbing.

A method can be provided that includes measuring sound waves using a sound measuring device, determining, at a central controller of an air mattress system, one or more parameter values of the sound waves, comparing the one or more parameter values with values, ranges, or patterns indicative of snoring, identifying a snoring state of a user, and initiating, with the central controller, a change to one or more adjustable features of the air mattress system.

A body support cushion is provided with layered foam which receives airflow and allows passage in predefined areas through the body support cushion. Additionally, a cover is provided including a spacer fabric that allows air movement from the body support cushion to improve ventilation of the user of the cushion.

A bed system detects and prevents user sleepwalking events. The system includes a sensor and computer system to receive data from the sensor during the user's sleep session, provide, as input to a sleep state classifier, a first portion of the data, the sleep state classifier using a machine learning model to determine the user's sleep states, receive, as output, a sleep state classification for the user, provide, as input to a bed exit detection classifier, a second portion of the sensor data, the bed exit detection classifier using a machine learning model to determine when the user exits the bed, receive, as output, a bed exit detection classification for the user, determine whether (i) the sleep state classification satisfies a first threshold condition and (ii) the bed exit detection classification satisfies a second threshold condition, generate, based on the determination, a probability of a sleepwalking event for the user.

A patient support apparatus pneumatic system may include a mattress defining an interior and a pneumatic enclosure in fluid communication with the interior and comprising an inlet and an outlet. A blower may be in fluid communication with the interior and the pneumatic enclosure. A pressure sensor may be configured to detect a pressure at the outlet. A controller may be configured to monitor a speed of the blower and the pressure at the outlet for detecting at least one of an intake blockage condition and an exhaust blockage condition.

An air bed system including a plurality of peripheral devices and a pump unit configured to adjust a firmness of an air mattress, the pump unit including a pump. The system further includes a controller configured to execute instructions that cause the pump unit to wirelessly pair with at least one of the plurality of peripheral devices. The pump unit is configured to receive at least one control signal addressed to the at least one of the plurality of peripheral devices, and transmit the at least one control signal to the addressed device.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.
