Abstract
A vertically adjustable and tiltable bed frame has two actuators which may be used simultaneously or independently to tilt the frame and which also may be used to raise and lower the frame. A level sensor is connected to the actuators so that if the tilt varies from the adjusted and desired position, one or other actuator is adjusted to restore the desired tilted position.
