My husband and I put the bed together in about 2.5 hours. The instructions could be a little clearer. Be aware that the cross slats are not all the same. We had to disassemble after we put two of the beds together. It was not clear on the instructions. I would not have been strong enough to put this together by myself. I would recommend a 6 inch mattress for the top and trundle. An 8 inch would be ok on the top if you had an older child that will not roll off.
