Abstract
An adjustable bed includes a platform having a flexible surface, a flex mechanism adapted to flex the platform to form a flexion position that includes at least one of a sitting-up position and a knee break, and a tilt mechanism adapted to tilt the platform surface laterally, the flex and tilt mechanisms both being operable with the other mechanism in an operational state. Furthermore, the adjustable bed includes a side member disposed on a side of the platform, and a side-member lift mechanism adapted to raise the side member relative to the platform surface, the tilt mechanism tilting the platform surface toward the side member raised by the side-member lift mechanism.
