This sturdy bed is perfect for our almost 4 year old. Its weight limit supports our whole family to cuddle in for books. It took my husband and father in law just under 2 hours to put together, with no difficulty. I love that I can stand on the floor and cover him as necessary at night. There are only 3 steps, so he can get out of bed to go to the restroom without worry of having to navigate a standard loft. He has a "play room" underneath. It is perfect. We are using an 8 inch mattress, and it fits well without worry he'll roll out. 

The original shipment came with 1 white box of parts and 2 cappuccino boxes of parts. A quick call to Wayfair, and they had another underway the next day!
