Very fast shipping, It took 3 hours or less to put it together, nothing complicated about it. I bought this bed for when my grand children stay over, the top bed is a full and the bottom is a twin, and it works wonderful, I have slept in it also and it is very comfortable. In the morning jusy roll the bottom bed under the top bed and you have all your space back! I would recommend this to anyone who needs more sleeping area and would rather not crowd a room with beds, I love it!
