Surprisingly good quality for the price. My woodworking husband thought he was going to have to make some customizations to improve stability, etc. but he didn't have to do any of that. It definitely will shake a bit when crawling up the ladder and no one should be bouncing around on the loft, but overall this is a really good value and perfect for our 9-year-old. I do wish the rails were a bit higher, though. But as a mom I think that about every bunk bed!
