Solidly built, well finished and easy to assemble.  Instead of buying a box spring for it I just used the included slats, cut a 1/2 birch plywood sheet to size and placed it on top.  Works a treat and keeps the overall height a bit more comfortable for our 3yr old daughter.  Good thing as she fell out twice in the first week of having it but no issues at all.  Soft rug landing helped and she hasn't fallen off since getting comfortable with it.
