skewed bed

A bed for two mattresses side by side, with a frame of four beams. Like the wall of an indigenous bentwood box, each beam is bent once round a corner: kerfed, steamed and folded, so the grain runs on unbroken round the corner. The beams lie round the bed like the sails of a windmill and meet at butt joints cut skew across the height of the frame. Under each joint stands a leg skewed at the same angle and centered on the joint line, which it carries on down to the floor. The headboard is two layers glued face to face, each broken in the middle by a skewed joint: the front one leans like the joint at the foot end of the frame, the back one like the joint at the head end. It rests on two posts that lean back with it. Set the mattresses, frame, legs and headboard in the control panel: the frame data gives the bending length of each beam and, measured from the inside corners of the frame, where to mark out the joints.
