Its a beautiful piece, but the assembly took a long time (I'm not the toughest girl, I admit) and my cats don't use it much. I have never seen one voluntarily go on the upper shelves (wobbly), in fact my two kitties will sit in the house or ON the house, or half heartedly use the scratch pad. One cat is a very active small kitten and the other is a 7 year old more lethargic female, so they are both of different temperment. They both lounge, sleep and play on this tree I bought them for the other room though. I don't recommend this as it is also a bit wobbly.
