Jeffers has the best price for this item. I read a lot of negative reviews and based on this being used against the sofa I agree. Cats like things to feel sturdy and secure and upright this isn't. I've been using it for a couple of years now. My only issue is durability which is why the rating is 4 instead of 5. The carpet could be secured better so that it doesn't lift with moderate use. But if you can find at low cost it's worth buying a few to last the year. I place thus post underneath a chair flat and the lip anchors in place against the a cross bar on the chair legs. My cat uses this thing 5 times a day if not more. He also likes to lay on it. If you can secure this properly and if your cat like carpeted textures they will love it. I paid 60.00 for a nice sisal post that is barely used. My cat finally told me he didn't like it by doing business there and I had to throw it out. I'm here buying more of these and he will be a happy camper!
