US Patent 7086103 Rotating bed with improved stability

A rotating bed is provided that has a base with a mattress frame supported for rotation about a vertical axis. The mattress frame is divided into sections and can be converted into a chair-like configuration in one rotational position. In order to increase the stability of the arrangement in the chair position, at least one support leg is provided that either contacts the floor from the beginning or only makes contact with the floor when the stability limit without the support leg is exceeded.
