An insert adapted to be inserted between a foundation of a bed and a mattress of the bed. The insert includes a frame having a first side rail and a second side rail spaced apart from the first side rail. A plurality of elongate upper slats extend between the first side rail and the second side rail of the frame at a first level with respect to the frame and are spaced apart from one another. A plurality of elongate lower slats extend between the first side rail and the second side rail of the frame at a second level located below the first level of the upper slats. Each lower slat is located below a gap formed between a pair of adjacent upper slats. A mounting member resiliently supports the ends of two adjacent upper slats and rigidly supports the end of a lower slat that is located below the gap formed between the two adjacent upper slats, whereby the firmness of a mattress overlying the insert can be selectively adjusted.

Provided is a quick assembly sommier box including end panels that have couplings on the inside and at opposite ends; and side panels that have couplings on the inside and at opposite ends. The upper face of each side panel has a step shape in the lower plane of which a Velcro strip is fixed. The couplings are defined by plates from which spaced apart eyelets project, which are able to receive a pin destined to penetrate all the central holes of the eyelets, with such pin being held in position by means of a cotter pin. The sommier box also includes bipartite bed frames, each composed of equidistant slats joined by Velcro strips. The sommier box defined in this way can be assembled extremely quickly and without the need for tools.

A slatted base having a frame and a measuring device for detecting the deformation of a lying surface under the load of a person lying thereon, wherein the deformation is carried out by detecting the vertical deflection of slats, which are held on both sides in a slatted base with their free ends in a mounting body, on which the displaceable end of a vertically oriented lifting drive engages, which is supported with respect to a bottom-side base frame, wherein the mutual horizontal distances between the slats is adjustable and fixable.

A ready-to-assemble bed foundation includes a pair of exterior side beams having two ends and a pair of transverse end beams having two ends. The beams can be assembled on site into a rectangular or square frame by joining one end of each side beam with one end of a transverse end beam. A drawer can be positioned between upper and lower surfaces. A protruding block on one beam is sized to fit into a gap between plates for registration of the beam to which it is being joined. At least one of the plates has a hole and the protruding block has an embedded threaded pin receiver positioned to align with the hole in the plate when a corner configuration is formed by the beams. A threaded pin passes through the hole and into the threaded pin receiver to retain the beams in a corner configuration. A single layer assembly can also employ fasteners at each corner.

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.
