We were going to buy bunk beds for our boys, but thought two lofts would be more exciting (since both boys were looking forward to dibs on the top bunk). These are sturdy, good quality, and the design is safe. Each boy has their own belongings under the bed, including a dresser. I wouldn't recommend buying for a kid who is already teen or adult- the maximum weight rating is 200 lbs. Unpacking, assembling and tightening took my husband and I approximately 1 hour each bed. The packaging was very gritty and dirty. Takes a standard twin-size mattress (no boxspring).
