Easy to assemble but the pieces are heavy and big - considering the height, I see that as a positive and a negative. Won’t knock over, but if you have a climber in your family, it will fall and do some damage. And since it spins, there is no anchoring that can be done. I set this up in my closet in the second floor of our house and had to open the box and make multiple trips to get it all up there. I ordered this in white, which I love, however the stickers that came with to cover the holes of the adjoining pieces were for the other brown color option. Since it’s in my closet it’s not a big deal, but I’ll always notice.
