I'm trying to make a chair from one I've seen, but I don't have the chair and from the photograph I can't really see how the seat is attached. I am attaching three photographs, a view of the seat from the side, bottom and top. (or at least I hope I am, as I haven't done this before)
My question is whether you think the seat slats are tendoned into both the front and the back seat rails or only the front. As the bottom view shows, the seat slats at the rear rest on and are secured to either a rabbited back rail or a board that functions like a rabbit. From the top view it doesn't look like the seat slats could be mortised and tendoned into the back seat rail because if they were it seems like they would cut into the back slat tenons. But is that rabbit or board really enough to hold the slats? They seem too tight up against back slats to just be abutting the rail and resting on a rabbit.
