The cat Mom gives this cat tree a 3, but the cat gives it a 5, so we agreed to meet in the middle with a 4.
This is NOT carpet - it is a VERY thin fabric which results in every surface being very hard as it doesn't provide any cushion against the hard particle board that it is made of. The "ceiling" of each cubby is completely bare...straight particle board. To resolve these issues I put a circle bed in each cubby to give her some softness and I used moleskin to line each "ceiling". Now to find something to cover the exposed screws that are all over this cat tree. My cat is in this tree all day everyday so it must be good despite what I don't like about it. And really all that matters is that she loves it.
PROS: Top bolster bed can be removed and washed; bottom cubby is made of felt and it comes with a second one in case you need to replace it; it is the perfect height to look out the window.
