Abstract
An under-mattress for a bed or similar article of furniture comprises a frame having two longitudinal limbs with elastic support elements attached to the inside thereof. The elastic support elements are located opposite each other in pairs for supporting spring bridges 3 disposed transversely of the mattress. Each spring bridge has formed therein at least one slot-like recess A extending longitudinally of the bridge and dividing it over a large portion of its length into parallel spring laths.

An undermattress for a bed-like article of furniture having a longitudinal axis, said under-mattress comprising:
- (a) a frame having two longitudinal limbs with insides,
- (b) elastic support elements, and
- (c) spring bridges each having at least one slot-like recess extending along its length and defining parallel spring laths laterally spaced with respect to each other at least over a large portion of the total length of each spring bridge,
- (d) said elastic support elements being attached to said insides of said longitudinal links in pairs and located opposite each other for supporting said spring bridges which are arranged transversely to said longitudinal axis of said under-mattress,
- (e) each support element possesses a lower portion which is mounted on two pins projecting laterally at the longitudinal limb of the bed-like article of furniture,
- (f) the upwardly facing outer surface of said lower portion being curved convexly upwardly and having a middle region supporting a downwardly convexly curved spring lath support which is constructed in the manner of a rocker,
- (g) said spring lath support comprises at least two holder elements serving for anchoring the ends of said spring laths.
An undermattress for a bed-like article of furniture having a longitudinal axis, said under-mattress comprising:
- (a) a frame having two longitudinal limbs with insides,
- (b) elastic support elements, and
- (c) spring bridges each having at least one slot-like recess extending along its length and defining parallel spring laths laterally spaced with respect to each other at least over a large portion of the total length of each spring bridge,
- (d) said parallel spring lath being independently flexible vertically with respect to said longitudinal axis,
- (e) said elastic support elements being attached to said insides of said longitudinal limbs in pairs and located opposite each other for supporting said spring bridges which are arranged transversely to said longitudinal axis of said under-mattress.
