A device for tilting the top end and/or bottom end of a bed, including two hingedly connected frames and a control unit operably connected thereto for adjusting the spacing therebetween, wherein one, fixed frame is supported on the bed base while the other, movable frame supports one end of a mattress. The fixed frame comprises two parallel coplanar tubes (109) and the movable frame consists of a U-shaped frame (105) pivotably mounted on and between said tubes (109). Said control unit is attached to the fixed frame and controls the longitudinal translation of slide blocks (110) by means of worm screws (111), said blocks being slidable along said tubes (109) to tilt the movable frame relative to the fixed frame. The worm screws (111) are mounted in said two tubes (109) and the control unit is located outside the area encompassed by the fixed frame.
