Although some of the pieces were not numbered correctly, I found it easy to build. The only part I needed a second pair of hands for was the hinges for the door. It is very sturdy and looks much nicer than most dog crates. It would not be good for a dog who is not accustomed to sleeping in a crate as the “bars” are farther apart than most crates but my pup settled right in and went to sleep for the night. I’m very pleased with the final product.
