bought for my 2 cats there a year, I had the wall mounted because every time one of my cat went up the cat tree disappointed banged against the wall and it was not very pleasant at night . I did not put the ladder because he got it wrong hole, the family tried to reassemble it, but it did not work so we let it go. Otherwise, I'm still satisfied enough of this cat tree, especially my cats sleep in the hammock and enjoy a max to get the claws. If you have the option of the wall mounted I highly recommend it.
