I USED THIS CAT TREE IN MY LIVING ROOM FOR SEVERAL CATS OF ALL SIZES.
THE ONLY THING THAT WAS GOOD ABOUT IT WAS THE BOTTEM 2 SCRATCH POSTS.THINGS THAT ARE NOT SO GREAT ABOUT THIS :
WHEN I RECEIVED THE TREE AND OPENED IT AS I WENT TO ASSEMBLE IT AND ONE OF THE ARMS WITH THE TOYS HANGING FROM IT WAS ALREADY BROKEN. THE LARGE STAPLES THAT HOLD IT IN PLACE WERE STICKING OUT AND BARELY HOLDING IT TOGETHER. WHEN I WENT TO ATTACH IT THE STAPLES THEN SEPERATED FROM THE POST..I HAD TO RE-ATTACH IT WITH A LARGE SCREW.
THE LOWER CAT BED AND POST BROKE WITH IN THE FIRST MONTH.
THEN THE TOP CAT BED AND POST BROKE OFF IN THE 3RD MONTH. NONE OF THE CATS USE THE CONDO. MOST OF THEM CANT EVEN FIT IN IT. THE ONLY 1 THAT CAN WENT INTO AND OUT OF IT. 
I FELT THE INSIDE OF THE CONDO AND IT IS VERY HARD ..BUT THE LARGER TREE I PURCHED ALONG WITH THIS ONE IS 100 TIMES BETTER.
