This crate took me about 3.5 to 4 hours to assemble. It's a beautiful piece of furniture. However, my golden retriever refused to sleep in it. She is 85 lbs. I think it was because she could really turn around in it. It was much narrower that her old metal crate. I ended up not being able to use it and sold it on Marketplace. Unfortunate that I had to sell because I really liked it but if you decide to get for just one dog, I would not use for a large dog but a medium sized dog.
