I love the bed!! I had a second person help me but it could be done alone of you have the time. You do need a screwdriver or drill but thats it. The bed delivers in 4 pieces and they all came at once. I have a 12 mattress (wayfair 12 hybrid) and it fits perfectly! also the trundle is a twin ! I honesty cannot wait to have movie nights its so beautiful and soft and high! It does take up whole room practically but I have a room and its worth it!!
