My cats love the cubbies but they are hesitant to get up on the platforms.  My cats are bigger and I dont think there is enough space between the platforms for them to feel confident climbing on them.  They had higher platforms on their previous tree and loved them.  The fabric is soft but thin.  I put blankets inside the cubbies for some extra cushion.

Review update! Some time has passed and my cats LOVE this cat tree. They now spend more time on the upper platforms and they pushed the blanket out of the cubbies. The only part they don’t use is the “hammock” on the bottom.
