Well made with predrilled holes. Very square when erected properly. Hints; pre sort all pieces and figure out how the connect.  Pre sort all screws for size. This is very soft pine and you must have the right screws to keep the wood from splitting.  I cracked a couple of pieces but quickly repaired using Gorilla glue. Tolat time to assemble, 1.5 hours. Nice when finished. I will use this as a pattern make one out of oak. Very satisfied with purchase.
