This is my second new cat condo, the first was the corner one and my cat loved it and it is fantastic. This one is okay as said in another review the middle perch is slightly slanted downward and a bit wiggly. Also, I set my perch on a 20 by 20 board to give it a bit more height and it seems the cat condo is a bit smaller than the actual dimensions but again not a big deal. The top perch is smaller than I expected, I was going to use it so that he could hang out by the window but there is really only enough room to sit or lay with a couple paws hanging over the end. My cat is only 10 pounds and not very big so I was hoping it was fine but i may be little small. My biggest concern is that there is a nail sticking out it in the middle perch and as hard as I try cant get it to bend back into the product so until I fix that that. It is off limits to Wisco.
