I just received this Cat Tree today and my cat's are going crazy over it!!!  I have 17 rescue cats and they are literately waiting in line to get in the cubby!   LoL  Even my big boy, that you have to pick up with 2 hands, can get in it.  I've even seen 2 cat's in it at once!  If I had the room, I'd order another one right now!  Very sturdy and I love that I can stain it to match my living room furniture, so it won't stand out like most cat tree's do. Thanks Archie and Oscar for a great product and thank you Wayfair for super fast shipping!!  Wish I could find more cat tree's like this!
