ABSTRACT The frame of an article of reclining furniture supports an under-mattress which comprises a back member and a foot member. The back member is mounted for pivotal movement about an axis in such a manner that upon pivotal displacement the inner end portion thereof is moved under the pivot axis and forms a sitting depression. In order to ensure for the occupant an anatomically correct support of his seat and back in all possible sitting positions and also to maintain this support even when changes of position are performed, an intermediate member is inserted between the back member and the foot member. This intermediate member is suspended at the adjacent ends of the back member and the foot member by means of joints and therefore together with the back member and the foot member, which is movable longitudinally of the article, it forms a system of joints which responds to magnitude and point of attack of the load and compensates for anatomical differences and permits the occupant any desired change of his sitting position. Dependently upon whether the changes his position forwards or backwards, the intermediate member will be flush with the back member or the foot member and thereby ensure always a correct support of the entire spine. The movable connection of the intermediate member with the adjacent ends of the back member and the foot member is effected preferably by means of an elastic joint whose two limbs of which are provided with teeth, so that in its closed position the joint may absorb without difficulty even vertical continuous loads. Thanks to elastic suspension of the intermediate member and the location of all metal parts into the interior, damage to the bed linen as well as accidents (finger injuries by clamping in) are largely avoided.
