Abstract
Abstract A bedstead with a reclining head-rest has a pair of longitudinal side members provided with spaced apart lateral pivots carrying swingable slat supports which are disposed opposite one another in pairs along the inner faces of the longitudinal members. Each pair of supports is provided with at least two angularly spaced slats of different stiffness so that either slat may be rotated into an operative position forming the support for the torso of the user.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
103 words
A bedstead comprising a support, a pair of longitudinally extending frame members mounted on said support, respective pairs of pivots projecting inwardly from said frame members at corresponding locations therealong, respective fasteners mounted on said pivots and angularly displaceable relatively thereto about respective horizontal axes of each pair of pivots, and at least two slats spanning the fasteners of each pair of pivots and fixed thereto in angularly spaced relation wherein a selected slat bridging each pair of fasteners may be disposed at a supporting surface of the bedstead, the two slats of each pair of pivots and fasteners being of different stiffness.
