Making the seat frame
Mill mortises for 6 x 40mm Dominoes in the ends of the front and back rails of the seat frame and in the inner faces of the frame's side rails. The back and front rails of the seat frame are glued between its side rails. I took the frame to a professional uphol- sterer to get it upholstered with foam on elastic webbing and covered with black leather. There should be 1/8" clearance on either side of the seat frame to accommodate the thickness of the leather.
In order to be certain that the chair was strong enough to withstand the stresses of frequent use, it was tested by placing a board across its side rails and having three people with a total weight of 576 lbs. stand on the board. The rear ends of the side rails were depressed by ½" under the load, but sprang back to their original position when the load was removed, and the joints remained intact.
