I researched many cat condos. Most had poor reviews of being flimsy, thin carpeting or to small for a grown cat. This cat condo is BIG, very sturdy and enough space for 4 or 5 cats. I have 2 cats and they love it! The carpeting is very thick and padded. Follow the directions slowly and carefully and you should have no problem building it. So glad I spent the extra money for a sturdy, well built product! Would buy again but I feel this cat condo will last a long time.
