We purchased this bunk bed to replace another one that we ordered here on wayfair and let me tell you, this one was much easier to assemble. With 2 people doing it, it definitely cut the time in half so I’d say it took us about an hour and a half. I wish the parts and screws were labeled more clearly but still we got it done. It definitely feels sturdy and has a great amount of space between the top and bottom bunk. The top bunk fits a standard 7 inch mattress with a bunkie board and still has room for the guardrail to serve its purpose. You won’t be disappointed with this purchase.
