Great bed! Super heavy box, needed 2 of us for sure to bring into the house and up the stairs. Easy to follow instructions. Took about 2.5 hours to put together. Toughest part was all the bolts are about 3” long and you can only finger tighten the first turn. The rest is slow and steady with half turns of the Allen wrench. My 5 year old (and 7 year old) love it. They played in his room for 3 hours the first day. Had it about a month and super happy with purchase.
