Sturdy and very easy to climb

The staggered design makes it so easy for my older cat to reach the top. She uses the 18×36.8 cm central ramp to get between the two towers instead of having to jump long distances. I like that half of the 18 structural posts are wrapped in sisal because it gives her plenty of places to scratch without ruining the plush parts. It is a very well thought out design for a heavy cat tree.
