It looks like the pieces are dadoed together and bolted. I guess maybe to be able to disassemble? It seems like there might be a better way…

I can think of other ways but not necessarily better.
Through mortise and tenon type joint where the seat and back have tenons that fit into through dados on the sides.
Cleats on the fastened to the sides and the seat and back fastened to the cleats.
Some type of over lapping and interlocking joints between the back, seat, and the sides. I use this method on a knock down child’s rocking chair where everything interlocked and was held with a locking wedge.
Blind dovetails that the seat and back slide into….won’t work well on plywood.

Simple as it may be, the back is to help prevent side to side sway. And the sides are one piece legs to prevent back and forth sway. You could add additional support to the back with screws in the sides attaching the back. drill a pilot hole first to prevent splitting of the wood. Some foot stools are designed this way also.

Through mortise and tenon

Doesn’t show very well this whole project was made with T M&T. If you zoom in you can see the tenons coming thru he side of the end.

There’s something odd about this pic. Looks like it was edited. The bottom of the legs don’t match the construction. Hope that makes sense. Anyway, the thru mortise seems like the nicest idea. Otherwise cleats under the seat are another way to go. Simply screwed together as shown doesn’t appear to be the best method IMO.

It looks like the cuts that are circled may have been routed to allow for stacking multiple chairs.

from experience with similar type of items they are rarely dadoed – these are usually aligned with alignment dowels, and pulled together with bolts.

not saying that’s the best way to joint this, but this is the cheapest and easiest to mass produce these parts. also makes it easy to break down and sell in smaller boxes (logistics)
