An adjustable bed is particularly adapted for the care of patients at home, and comprises a stationary frame, and a mattress support having a head section, a center section, and a foot section, which are hingedly interconnected. A lift arm has opposing ends thereof pivotally connected with the frame and the mattress support center section respectively, and includes a power device which selectively pivots the lift arm to raise and lower the mattress support thereby adjusting patient elevation. A longitudinally extending motor has opposing ends thereof pivotally connected with the frame and the mattress support center section at a point spaced from the lift arm center section pivot, whereby motor extension and retraction pivots the mattress support about the lift arm pivot, thereby bodily tilting the same for adjusting patient inclination.
