This “z” chair is constructed of sassafras with catalpa splines.
I first saw this type of chair on one of Rowdys posts:
Daren has made a similar “C” chair:
The strength is provided by tapered dovetail splines:

If mom sees this, she might change her mind about that pesky catalpa we have in the backyard ;)

Nice chair. I like the dovetail splines. That must add a lot of strength in the critical area!

Very nice, very nice. If I ever build another one I will use solid wood like you did instead of plywood. I found this project to be a pain in terms of the time I put into it, so I may not make another one. Anyhow, I am glad to see that there is another one out there. The dovetail splines really work well. Congrats on a good job.

Spot on. An excellent example of the Gerrit Reitveld ‘Z’ chair. Well done.

Rowdy: It is deceivingly simple. I’m sure anyone who has built one knows this. I can imagine the plywood version would be even more difficult.

Sodabowski: Catalpa is a great wood if you ask me. Rot resistant, light weight, and easily worked. Last time I used it I even found some with curl. Top box in pic 1

Jim Jakosh: The key is the 1 degree taper in the splines.

Mads: Thanks for stopping by.

BritBoxmaker: Thanks for the info on the original.

Here is what MoMA has to say about the original.
