I got this loft bed for my 6 year old son.   He loves it.   I was able to put it together by myself, though it took me half the day.  It would have been faster with help but my husband was sick and I didn't want to wait.  It's very solid and sturdy. I'm very happy with it. You can see in the photo that my younger son's regular twin bed fits just under the loft so we can better fit their two beds in their small room.
