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.

A foundation for a bed system can include an actuator, a deck mechanism operably related to the actuator so as to be actuated between raised and lowered positions in response to actuation by the actuator, and a controller operably connected to the actuator and configured to drive the actuator to actuate the deck mechanism between a lower position and an upper position. The deck mechanism can be configured to move to a service position that is further than the upper position. The deck mechanism can expose and permit access to a serviceable component when the deck mechanism is in the service position. A method of using a foundation having a service position is also described.

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.

A multifunctional mattress overlay of the present invention comprises an air cell body, a gas pipe set and an inflating device. The air cell body has multiple first and second air cells. The first and second air cells both have a left and right air chamber. The gas pipe set respectively connects to the left and right air chambers. The inflating device is connected to the gas pipe set, and can selectively inflate and/or deflate the left and right air chambers, which makes the air cell body show an alternate state. The inflating device can inflate and/or deflate all the right or all left air chambers separately, which makes the air cell body show a turnover state. Through it, the air cell body can selectively in the alternating state or the turnover state, which makes the air cell body massage the patient and also assist the patient in turning over.
