This went together in less than 5 minutes, which was great, and came with the wrench to tighten the connecting pieces. So far, my cat is a little hesitant with it because it's new, although she likes the scratching post. It seems like it should be easy to swap out the post once it gets frayed with another of the same bolt size (I believe they are standard). The material is very soft, the sides are plush, and the unit feels sturdy.
