Both of my cats use this.  Took them a few days to get used to it, but now it's a daily nap spot.  One sleeps on top. The other sleeps inside the cubby.  They now love to use it as a perch to jump across to the couches.  The scratching part looks perfect, but the white carpet did shred a little as you can see in the left of the picture, but I just moved that to the wall side.
