Abstract: An insert for a piece of lounging furniture comprising a frame and a plurality of resilient slats of different elastic properties spacially arranged for forming a slat grate, the slats being arranged in at least two superposed rows and staggered in relation to one another in a horizontal and in a vertical direction, wherein the slats of the upper row have greater elastic resilience than the slats of the lower row.

Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.

Abstract: A box spring mattress is supported a predetermined distance above a floor by a bed base including panels connected at their ends to form a rectangular frame and a pair of cross-supports resting crosswise on the edges of an opposed pair of notched panels. Each cross-support has a generally flat surface which is generally parallel to the floor and on which the box spring rests, and a downwardly pointing brace. The braces nest in the notches in the panels and the support surfaces are essentially flush with the unnotched portion off the notched edges of the panels. Each brace includes notches which lockingly connect with the notches in the panels so that the cross-supports cannot move laterally relative to the base. There are stop members at the opposed ends of each cross-support for restricting the lateral movement of the box spring relative to the base.
