We have this cat tree since late August The delivery was very quick (3 days) and in perfect condition; mounting with map and photos provided in support of the site is not complicated. The upper house is big enough for a cat :-) coated and the whole is very stable while our three cats spend their time on. It is true that the little house down is not very stable because on one foot but obviously when you're a cat is still great fun to pitch it at times! The hole in this house (unlike the upper one) is very small and our cats do not go in, but frankly seen all floors, hammocks, this cat tree is really complete. The fabric is of good quality, and soft. He has already served for more claws. The fact that it is in the corner makes it more stable (I compare with other trees we had) and what has pleased our cats is that most platforms are wide enough to lie on. From our side, no complaints about that tree!
