Crib Mattress Bunk Beds

We took existing twin size bunk beds and modified the measurements to fit for 2 crib size mattresses. 1 for my 3.5yr old and the bottom for my soon to be 2yr old. It took us 12 ours to build from start to finish then about another 1hr to place in room and set it up completely. All in all they love them and sleep thru the night in there own beds lol. I also have a 7mth old in my room too...
