My cats were all over it while I was assembling it.  It took me some time to put it together, but that's because I wasn't paying enough attention.  It looks great and I like that it is covered in fleece and doesn't "shed" like the carpeted ones do. My 2 cats are very happy with it and like the high levels, the sissal rope scratchers and the houses.  I feel I got a great deal on a great product.
