Howards offer will give you an excellent start, a search on this forum for mosely air cushions will provide modern bicycle large tube replacement options. Modern foam in high density is readily available and cans of spray contact glue, domestic electric carving knife and your angle grinder are your friends.
Howard's seat backs show wood tacking strips around the backs and there was some thin ply along the bottom inside and out. Depending on your originality intentions its common to sew both the pleated front and plain back into a sort of piped slipcover and simply pull it on and tack at the bottom only.
The stitching of the pleats is always invisible as are the rivets holding the covered panel which wraps around the lower frame .
