This is the first chair one can make, it's a common pre-industrial chair design. Search for "tribal chair" or "2-piece chair" for examples.

It gets even better with wood carving (rather than building out of straight planks):

How do you carve solid wood board ?

I've done ten's of carving by gluing thin layers in a mold to create carved plywood. Those are extra strong but required to use quite a lot of glue and get the right thickness wood veneers. Would love to learn the solid board way.

edit: fined tuned my English today: seems carving means sculpting and not bending.

The traditional methods of "carving" I know about are using an adze [1] and controlled burning [2].

In my chairs I just sculpt the back out of eight quarter with an angle grinder. More production focused wood workers are using multi-axis routers/cncs.

The english term for what you are referring to in bent lamination which is done by taking a piece of wood, slicing it to sections with a thin kerf blade, soaking in water, and then clamping to a form and gluing back together. This is how Russ Filbeck creates his classic presidential rocker.

Bending solid wood is something you do while it grows. See for example https://fullgrown.co.uk/, https://en.wikipedia.org/wiki/Espalier or https://www.core77.com/posts/27263/Polands-Forgotten-Crooked...

I've seen people doing it with steam

And you can bend surprisingly thick wood with steam. I attended a demonstration where someone bent a maple 2 by 4 (1.5" x 3.5"). It took about 6 people and two tries (the first one splintered, probably not steamed enough).

And gets pricier too. The prices are absolutely eye watering!
