You definitely need 2-3 people to put it up.  Easier if you unpack and put pieces in a separate pile. Better if you have people with some construction experience.  Spent 4 hrs first day with son and the second day about 6 hrs with son, wife, and daughter.  Instructions are good.  All pieces were there.  Quality materials.  We really like it.  Only pain was the small side pieces you had to put in each panel and slide them into place. Weird design but it works.
