This was very easy to assemble and matched what we wanted for our two cats (a 1yr old and a 12 yr old). We wanted a tower that would provide enough entertainment for the kitten and enough ease of access for our senior. They both enjoy it, and despite them not being best friends, will use it together. I was reluctant to get a tower that wasn't carpet, but this material works fine. The cats both love the sisal rope-bound posts and the variety of the multiple tiers.
