Took an afternoon and evening to put it together, mostly by myself. Made sure all pieces and parts were included first.  Directions were clear and well illustrated. Need 2 people to get the bed on the loft kit. Recommend power drill for screwing in brackets and slats other than that only needed the tools included with the parts. Very sturdy and solid. 2 year old up to a 50+ male has been on or slept on the bed and it doesn't shift or move. Purchased for a 5 year old; perfect height and loves being on top and underneath the bed.
