Needed a TwinXL for my son, and this bed fit the bill.  Arrived quickly and couldn't have been easier to assemble.  Good height off the ground so he can slide his backpack and other things underneath, unlike some of the really low, nonfunctional ones.  
Box is VERY HEAVY and takes two people to carry it upstairs.
Put a Memory Foam mattress on top of the platform, and is a good height.  If you like a higher bed, you may be able to put a boxspring or something to give it some lift.
