Excellent Quality! And super cute. Fits well in a small guest bedroom. Currently have a 5 inch mattress on top but there is room for a 7 inch to have the arms still showing, an 8 would be flush with the sides' height. No mattress currently on the trundle, I use it for storage, low profile under-the-bed boxes fit perfectly. 
Came with all parts and zero damage. Quite heavy, so build it in the room where its gonna go!
