These stools were each made from a single sheet of poplar plywood. Each is laminated from a total of 80 pieces - the layers are 5 pieces each, mirrored with each layer, creating a "box joint" at the corners. The seats were carved out with a router jig, the side cut with a skill saw, and the rest of the curves carved with an angle grinder and sander. And yes, these seats are incredibly comfortable!

That skill saw cut is not for the faint of heart -- DO NOT attempt unless you are very comfortable with your tools!
