Takes two people and more than a couple of hours to assemble. Be sure to follow the instructions included and use the online video, included with the pictures of the bed, on the Great Offer Stock website. Otherwise, connecting the bed to the upright frame can be a real challenge. If you are installing this over carpet, check to make sure the bed doors clear the bottom cross support when the bed is closed, otherwise the doors will rub on it. I had to screw the bottom cross piece to the floor to prevent rubbing. I suggest overlapping two pieces of VELCRO, attached to the inner bed frame, across the center of the mattress to secure it in place. Not sure yet if the laminate material is strong enough to sustain regular use over a long period of time.
