Mattress has a casing and a foam body accommodated in the casing. A support apparatus adjustable by electric motor is provided, having a base body with two support parts which are adjustable relative to one another and bear spring elements. Situated on support apparatus is an electric motor-driven adjustment apparatus for adjusting support parts relative to one another, and which has an electric motor in operative connection with the support parts to adjust them. An electrical line arrangement has power supply lines for supplying power, and/or control lines for controlling the adjustment apparatus. A recess is in the foam body, and dimensioned to accommodate the support apparatus together with the adjustment apparatus in the recess. Support apparatus together with adjustment apparatus are accommodated in the recess, and the line arrangement is led out of the casing of the mattress through an opening in the casing.

A bed frame having flexible slats which are adjustable in a horizontal plane and having at least one bearing element for supporting one end of at least one flexible slat on a longitudinal beam of the bed frame is provided. The bearing element is movable over an arbitrary displacement path along the longitudinal beam. The bearing element includes a housing which accommodates the respective end of the flexible slat and in which at least one spring-loaded detent device, which is actuatable by hand, is situated and which engages with associated receiving profiles in the longitudinal direction of the longitudinal beam and is lockable at that location.

A platform bed frame particularly adapted for hotel use is provided including a pair of slat supporting rails that have a plurality of cavities along the length of the slat supporting rails. A plurality of slats form a mattress supporting surface and span between the slat supporting rails and have end lower conforming surfaces that fit into the cavities to secure the slats to the slat supporting rails. There are side rails and end rails that snap onto the slat supporting rails so that the assembly of the platform bed frame can be accomplished without the use of tools. There are two component legs that also allow an adjustment of the height of the platform supporting platform between a high and a low position. In the low position a foundation may be included underlying the mattress and a lesser number of slats can be used.

Mattress foundations and kits include a first side rail, a second side rail, a first end rail, a second end rail, and at least one center rail. The foundations and kits further include a plurality of slats of varying lengths. The invention may further include a method of assembling a foundation kit.

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.
