Seriously, shop around and you'll see! For this price, most places sell a single tower with a couple of places to sit.  My daughter's cat (Alice) loves this.  I only gave it 4 stars for two reasons: 1) is that all of the components are a little small. Alice is about 8 pounds and can moves around fairly well (she is a cat, after all), but with not a lot of extra room.  So, if you have extra-healthy cats, this may not be for them. 2) The high-rise resting places won't stay secure. By that I mean, we can't get them tight enough to keep from twisting. They haven't fallen off nor does this seem to bother Alice. It does, however, bother my OCD daugther. :-(  Anyway, overall, we're happy with the produce!
