Cats love this. Its is important when you have 1 or 8 or more indoor cats to give them places upward since cats love being above things. Gives them places to scratch instead of on your furniture. Also Gives owners free couches and bed because cats like to hang on the towers to nap and watch you. And the price...WOW its unbelievable what a deal!  No way you can buy parts and make your own cheaper.. Nice to look at,  Sturdy, clean neat easy to put together. You cant go wrong.  I put mine in front of any picture windows. They enjoy watching birds, also when windows are open the fresh air and sunbathe in sunshine. Youll have happy cats.
