Abstract
An adjustable bed includes a base frame and a mattress frame having a plurality of pivotally interconnected sections. A plurality of links are positioned between the base frame and the mattress frame. The mattress frame may be moved between a high position and a low position. A single linear actuator is connected to the mattress frame. The actuator is extendable and retractable to raise and lower the mattress frame with the mattress frame sections in a common plane. The actuator may also be retracted when the mattress frame is in the low position to articulate the mattress frame sections.
