A bed chair apparatus has a user support surface which includes a back section 1, a seat section 14, a lower leg section 15 and a foot section 16 that are configured to articulate relative to each other. The support surface is configurable in a bed configuration in which the support surface is substantially flat and in a chair configuration in which the foot section 16 is disposed beneath the seat section 14. Some embodiments of the apparatus require only a single actuator 30.

A sofa bed with three moving seat bases that transforms between a bed configuration and a sofa configuration. The sofa bed includes supporting legs and armrest. Each of the seat bases, and corresponding cushions, are located between the armrests. The seat bases are interconnected with a set of slide rails that allow the seat bases to move relative to one another. The sofa bed also includes a locking mechanism to hold the sofa bed in the sofa configuration.

Disclosed is a folding sofa bed, including a folding bed frame body, a cushion body, and a turning component. The cushion body is disposed above the folding bed frame body. The turning component is connected with the folding bed frame body and the cushion body. The turning component is capable of driving the cushion body above the folding bed frame body to turn to be below the folding bed frame body. In this application, when the folding sofa bed is unfolded, the cushion body may turn to be below the folding bed frame body through the turning component. This may not only save space, but also bring convenience to a user for operation.
