This is a fantastic product, very easy to assemble and very high-quality. I put the entire thing together including cleanup of packing materials within two hours. Only one kind of bolt.  Very sturdy, solid wood. Just a note that if you were going to reverse the alignment of the benches, there are no instructions for how to do it. You have to swap sides from the small bunch in the long bench. Very sturdy, solid wood.
