We had the bed up for my 60 pound 8 year old on the top bunk and my 40 pound 4 year old girls on the bottom for 3 months and the bed began to crack.  There is already a crack on each leg that connects the top bunk to the bottom bunk (longitudinally) and there's a crack on the piece that connects the foot board to the top bunk.  My kids don't even play on their beds.  The wood for this bed is extremely low quality, and now it is a safety hazard.  We are very disappointed.
