This set was a lot cheaper looking than I had anticipated. The material is something like an inexpensive school backpack. Was expecting more quality for the price. We bought a couple of modular sets and put them together to create a fun environment for our cats - but sadly, they don't really use them, which is disappointing. They much prefer other cat trees and toys that we have. We find the unit to be really bulky too and dust really clings to the brown surfaces.
