The bed looks nice and is seemingly made well.  The issue is, anyone sleeping on the bottom (which would e the main because its larger) doesn't have adequate space.  There is not enough height between the bottom and top bunk.  My 11 year old hits her arm on the bed above when she turns over. 
It would be OK for a child(4-8), but then you wouldn't really need a full-size bed on the bottom. Once you assemble it you can see it's obviously its just a little kid's twin bunk set that they added and extension on so it can accommodate a full size mattress on the bottom.
