It went together within minutes easily and is a sturdy tower. We have never had any concerns about it tipping. All of the scratching posts are divine...because it saves our rugs! I love the fleece material over the typical carpet because there is no shedding! The only issue we encountered, a very minor one at best, is the bottom step platform is not meant to withstand the weight of heavier cats, so ours has cracked is limps downward. The cats only used it to step on momentarily and then back off since it is easier for them to access the tower from the floor or furniture next to the tower (as we have). Fast delivery, and I love free. Thanks WayFair!
