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.

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 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.

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.

Disclosed are techniques for temperature control of a bed. A system can include a bed having first and second sides, the bed having a mattress, a first thermal module on the first side, and a second thermal module on the second side. A computer system can receive data about the bed, such as temperature, pressure, heat routine activation, and cool routine activation data for at least one of the first and second side, determine that a heat routine is activated on the first side based on the data, detect that the second side is unoccupied by a user, generate, based on (i) the heat routine being activated and (ii) the second side being unoccupied, instructions that cause the second thermal module to activate a heat crosstalk mitigation routine, and transmit the instructions to the second thermal module for activation of the heat crosstalk mitigation routine on the second side.

A bed integrates sensors and other inputs to detect specific sleep environment conditions including point-specific pressure and/or temperature conditions. The bed includes a controller for commanding actuator or other devices to adjust these conditions. The controller may do so based on reference patterns for conditions and profiles of desired conditions. Information regarding the conditions may be provided to a remote computer, which may analyze the conditions and provide revised profiles of desired conditions.

Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, respiration rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.
