Patent attributes
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.
