A bed includes a frame installed horizontally with respect to a floor, a plate installed over the frame and having an end portion that is inclined upward with respect to the frame, an arm that supports the plate over the lower side of the plate, and a sensor attached to the arm.

An adjustable bed system includes first and second frames; a back lifting assembly having a back lifting bracket pivotally connected to the first frame and a back lifting actuator pivotally connected between the back lifting bracket and the first frame for operably driving the back lifting bracket to pivotally move in an upward or downward rotating direction relative to the first frame; a leg lifting assembly having a leg lifting bracket pivotally connected to the second frame structure and a leg lifting actuator pivotally connected between the leg lifting bracket and the second frame for operably driving the leg lifting bracket to pivotally move in an upward or downward rotating direction relative to the second frame; and a foldable connection mechanism connecting the first and second frames such that the first and second frames are pivotally foldable relative to one another at the connection mechanism.

An adjustable base is provided that includes a fixed frame and an articulating frame connected to the fixed frame. The articulating frame includes an upper body frame pivotally connected to the upper section of the fixed frame, a seat frame pivotally connected to the upper body frame and movable along a central section of the fixed frame, and a leg frame pivotally connected to the fixed frame. An actuator is further included and has a first end connected to the seat frame adjacent to the leg frame and a second end that is connected to a linkage attached to the articulating frame. Upon activation of the actuator, the upper body frame is articulated upward and the seat frame moves linearly along the central section of the fixed frame toward the upper section of the fixed frame. Systems and methods for controlling an adjustable base assembly are further provided.

Adjustable mattress assemblies and processes including an adjustable mattress foundation dimensioned to support a mattress configured to accommodate two supine users during use thereof includes a foundation frame including a first sub-foundation configured with at least one motorized actuator to effect inclination or declination of the mattress support surface and an abutting second sub-foundation free of a motorized actuator. The second foundation is mechanically coupled to the first foundation such that articulation of the first sub-foundation results in a similar articulation in the second foundation. The first and second foundations have similar length, height and width dimensions, which collectively approximates the size of the oversized mattress configured to accommodate two supine users, e.g., king size, queen size, California king size, or the like.

A lateral rotation apparatus includes a first adjustable frame positioned under a head segment of a person support surface and operable to rotate the head segment of the person support surface to a head tilt angle in the range of about 7 to about 30 degrees relative to a horizontal support plane. A second adjustable frame is positioned under a torso segment of a person support surface and operable to rotate the torso segment of the person support surface to a torso tilt angle that is within a range of about 5 degrees to about 10 degrees less than the head tilt angle. Each of the first adjustable frame and the second adjustable frame includes an upper frame positioned below the person support surface, and a lower frame coupled to and positioned below the upper frame. The upper frame being moveable with respect to the lower frame.
