Perfect for my 3 year old and my 4 12 year old. They love it. Pretty sturdy and very easy assembly. The only negative thing would be the wooden platform part the pieces of wood are very thin and could easily break of the kids decided to jump in the bed. We will be adding a sheet of plywood just to be safe. Other than that we are sooo happy with it. My son still gets up in the middle of the night to come to bed with me and gets on and off the top bunk just fine
