A bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

The present invention discloses a turning air mattress, a turning air cell, and a control method for a turning air mattress. With structural arrangements of an upper portion and a lower portion of the turning air cell as well as inflation and deflation control, the turning air cell having an upper portion that is wider and a lower portion that is narrower can further assist a patient in body turning, enabling the patient to easily achieve a sufficient body turning angle, further reducing the risk of likeliness to pressure sores caused by the structure of the air mattress pressing against the body of the patient.

A bed includes environmental control components, which may be temperature control components and pressure adjustment components in some embodiments. The environmental control components may be configured to provide different sleep environments based on identity of sleepers using or expected to use the bed. A controller may determine a number of sleepers for the bed, identify the sleepers, and determine if there is an expectation of later arrival of sleeper in determining a configuration for the environmental control components in providing a sleep environment for the bed.

A seat device includes a seat cushion where a sitting person is seated, and a seatback configured to support the upper body of the sitting person. The seatback includes a seatback frame, a seatback pad placed on a front face of the seatback frame, and a seatback cover covering a surface of the seatback pad. A plurality of stretch airbags is provided in a part of the seatback at a position corresponding to the lumbar part of the sitting person, and the stretch airbags are configured to inflate and press a surface of the seatback to a direction approaching the sitting person. The stretch airbags are placed to overlap each other in a thickness direction of the seatback such that the seatback pad is sandwiched between the stretch airbags.
