It is a beautiful set. Very sturdy hard wood. A written step by step assembly sheet would have been helpful. Because of the weight of the beds we decided to put both beds together minus the support slats. We then were able to lift and stack the beds. We then added the twin slats and then the full bottom slats. I agree that the trundle does not accommodate a twin actress very well. Our is a standard twin and not real thick; however, we are notable to make up the trundle and slide it under the full. It barely fits with just the mattress. The legs on the double need to be about 3 inches longer. It looks great and our grandchildren will love it.
