You can build this bench out of just about any type of wood. We made it out of pine, all cut out from one flat 1x12 board. If you want it to be a little more durable, you might consider a hardwood like oak or maple. In that case, you may have to start by edge-gluing narrower pieces into an 11 1/4"-wide board. No matter what you use, start with a flat board, because it’s easier to join flat pieces together tightly.
