My cats took to it right away - while it was being constructed.  Easy to assemble.  Does rock somewhat, but that is with 2 Maine Coon adolescent cats running full tilt to jump on it.  Has not tipped over and is virtually freestanding in the middle of my livng room.  Would recommend it to friends and buy again if I needed another one.  And the cost, including s/h was still at least 40% less than the local pet stores were selling them for.  The fleece does not collect the fur - I also have a shephard husky mix dog whose hair seems to get everywhere and even his does not show on the fleece.  Easy to vacuum and clean.
