So far after 1 day of it being in my house, my 7 kitties love it. No assembly needed, comes all built right out of the box, all you you is open it. It has a scratch area only on one side, I wish it were on both, the other side is lined with the same brown material as the unit. The little hammock above is filled with foam padding, very thin but so far it seems to hold the weight of my heaviest kitty who is 23lbs. I dont see this lasting forever since they have to jump on it to get to the hammock but for the price its decent. Id purchase this again if I had to. Quick shipping too!
