I have a medium sized one. It is carpeted, has sisal poles and has about three perches. Even Gabe likes it. They use it to scratch, sleep, sit etc. etc. One of the pictures in my signature shows Miley and Graemer sitting on the top perch. They are usually very heavy, so take a strong man with you to help you carry it. I also have four scratching posts distributed throughout the house - so they have no excuse!
