We bought this for my four-year old daughter. She loves it and tells us so every time she plays on it. It wasnt difficult to assemble. We did it in two days. The first day, I worked by myself. The second day, my husband helped by bringing me things and being an extra set of hands to hold things. I couldn't imagine putting this together without a power drill, so I'm very happy they included drill bits for the star-shaped bolts. We are very happy woth our purchase.
