Furniture spring systems are configured to provide support for different sized modular seating systems and/or modular bed systems. Slats extend between opposing frame or rail members to provide support to the seating or bed system. The slats have a catch disposed at a first or second end. In the seating and/or bed frame systems, the catch engages a retention member to retain the slat to the frame or rail. Adjustable bed frame systems employing such slats comprise modular bed frames and adjustable head boards and foot boards. Bed frames employing the slats and headboards/footboards thereof adjust in length or width in a variety of different manners. Adjustable bed frames adjust through the use of telescoping members, filler blocks and/or elongate end blocks that have different sizes from the standard uniform elongate support blocks employed in a bed frame.

A bedstead includes a frame, an interior support removably coupled with the frame, and outer legs supporting the frame when the bedstead is set up. The interior support includes an inner leg, first connectors disposed circumferentially around the inner leg and connecting bars. Each connecting bar has one end pivotally connected with the inner leg through a first connector, and the other end to be removably coupled with the frame. When in use, the first connector restricts the movement, in particular, the rotation of the connecting bar, and thus enhances the overall structural stability of the bedstead.

A system for adjusting the firmness of a substrate configured to support a subject includes a first rod configured to be movable by a mechanism, a second rod parallel to and spaced from the first rod a distance that spans a majority of a dimension of the substrate, and flexible straps extending between the first rod and the second rod and attached to the first rod and the second rod at respective ends of each flexible strap. The mechanism is configured to move the first rod in a first direction to increase tension on the flexible straps and move the first rod in a second direction to decrease tension on the flexible straps. The mechanism can be manually operated by the subject or can be a motor that is controlled by a controller.

A bed frame includes a frame, bed legs, and a bed plank support frame. The frame includes two side boards, a head board, and a tail board. Respective bottoms of opposing sides of the two side boards are provided with a plurality of U-shaped connecting members, respectively. The bed plank support frame includes a plurality of support members. Two ends of each support member are connected to U-shaped connecting grooves of the corresponding U-shaped connecting members of the two side boards, respectively. The bed plank support frame is sunk when in use. After a bed plank is placed, there is a certain distance between the bed plank and the top of the frame, so that the frame can form four stop sides. After a mattress is placed on the bed frame, the mattress is restrained in the frame, not sliding.

A moving bed has a fixed bed part as a resting area for the head and upper body of a person, and a longitudinally moving bed part as a resting area for the buttocks and legs of a person. The bed has a first bed frame in the form of a stationary fixed frame that extends as a stationary longitudinal frame over the entire length of the bed and on which the upper, fixed bed part is formed. The bed has a second bed frame as a moving frame, which forms the lower longitudinally moving bed part; the moving frame is held to the fixed frame so that it can move longitudinally. A motor drive is mounted between the fixed frame and the moving frame, and by this motor drive, the moving frame may be moved alternatingly back and forth relative to the fixed frame in a predetermined longitudinal section.

Method and apparatus for metal bed stays designed primarily for usage on bunk beds, but which could be used on any type bed wherein the metal bed stay includes a horizontal portion upon which the mattress or a supporting Bunkie board would rest having opposing ends wherein each end is fastened to an opposite left and right bed side rail. The bed rail includes a horizontal cross piece which could be of any shape, but may be round, having opposing ends having an upward vertical leg on each end including a 90 degree bend portion with a thickened portion above the bend along with a transition area which transitions to a flattened portion which is wider so as to receive a plurality of apertures therein through which fasteners pass in order to attach the vertical leg portion to the inside surface of the opposing left and right bed side rails.

A mattress foundation includes: a head end panel assembly; a foot end panel assembly; a left side panel assembly; and a right side panel assembly, all slidably attaching to each other using sliding mechanisms. At least one of the sliding mechanisms includes an elongated slot and an elongated protruding element that fits within the elongated slot. A horizontal cross-section of the elongated slot and/or the elongated protruding element includes thin elongated flexible arms, attached at their proximal ends to a common surface, but otherwise extending away from such common surface and separated from each other. When viewed from the horizontal cross-section, the average thickness of the thin elongated flexible arms is substantially less than the length of the thin elongated flexible arms.

Devices and methods for generating synthetic cardio-respiratory signals from one or more ballistocardiogram (BCG) sensors. A method for determining item specific parameters includes obtaining ballistocardiogram (BCG) data from one or more sensors, where the one or more sensors capture BCG data for one or more subjects in relation to a substrate. For each subject, the captured BCG data is pre-processed to obtain cardio-respiratory BCG data. The cardio-respiratory BCG data is sub-sampled to generate the cardio-respiratory BCG data at a cardio-respiratory sampling rate conducive to cardio-respiratory signal generation. The sub-sampled cardio-respiratory BCG data is cardio-respiratory processed to generate a cardio-respiratory parameter set. A synthetic cardio-respiratory signal is generated from at least the cardio-respiratory parameter set and a cardio-respiratory event morphology template. A condition of the subject is determined based on the synthetic cardio-respiratory signal.

The present disclosure discloses a reinforced bed frame. The reinforced bed frame comprises a plurality of bed poles, two cross poles, at least one connecting member, and a plurality of movable buckles. Each of the at least one connecting member comprises a body and at least two fixing buckles connected to the body. Each of the plurality of movable buckles is configured to cover an opening of a corresponding one of the at least two fixing buckles and cooperate with the corresponding one of the at least two fixing buckles to surround a corresponding one of the plurality of bed poles.

A frame system that is adjustable in size and shape is provided with components that move in relation to each other. The frame system uses two main bar rails having at least one short channel piece and a housing piece. The frame system also includes two side bar rails of at least one long channel piece and the housing piece. A pair of center bar rails attach to the side bar rails and include at least one strut extension piece and a strut housing piece attached to a center leg. The corner assemblies include a corner piece to receive an end of a main bar rail and an end of a side bar rail, a corner leg, and a bracket.
