An electric bed having no bed board and being covered with a surface material includes: a foldable bedframe jointed through connectors and connected with bed legs, overturningly foldable frames disposed on the bedframe, a drive device disposed on the bedframe (1), a surface material covered directly onto a plurality of frames, and a tensioning mechanism for tensioning the surface material at a surface of the frames; the tensioning mechanism includes embedded strips and pipes, and may further include a clamp fastener; when the surface material is in a tensioned state, an embedded strip connected at one end of the surface material is limited within a limiting slot of a pipe at one side, and another embedded strip connected at another end of the surface material is limited within a limiting slot of another pipe at the opposite side.

A bed device includes: an operation section that receives an operation input; a controller that controls a movement of the bed in accordance with the operation input; a detector that detects a position of a patient on the bed; and, a limitation table that stores a limitation area set on the bed in association with a limitation content, wherein when the position of the patient detected by the detector is included in the limitation area, the limitation content is read out from the limitation table so as to control the controller in accordance with the limitation content. With this configuration, it is possible to provide a higher safety bed device which can not only notify the danger based on the bed movement but also limit the movement of the bed in accordance with the status of the patient or the bed device.

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 zero gap foldable powered bed comprises a bed frame and a sliding mechanism disposed upon said bed frame. The bed further comprises back, lumbar, seat, thigh, and leg decks operatively connected to the sliding mechanism, and the bed frame includes a head end frame member which is disposed within a vertically oriented plane. Linear actuators are operatively connected to the back and leg decks, and when the back deck is elevated or lowered, the sliding mechanism slides upon the bed frame so as to maintain the head end frame member, to which a headboard may be attached, within the vertically oriented plane such that a free end portion of the back deck will always be disposed immediately adjacent to the vertically oriented plane such that the back and shoulders of a person, lying or sitting upon the bed, will remain close to a nightstand, which may be disposed close to the bed, such that articles disposed upon the nightstand are always readily accessible.
