The cat tree is very sturdy and well put together. The bed size is very roomy so even a bigger cat will fit comfortably. Unfortunately, and it isn't just this tree, I've found that when these trees are built with various levels, the cats are not actually a part of the design process, but what looks good is. The levels are basically on top of each other, so unless you have part cat, part monkey, it is very difficult for the cats to actually get up and down. 

The tree comes in 2 parts and is very easy to assemble, but I would rather spend a week trying to put together a cat tree that actually works for cats than let them injure themselves on something that really hasn't been thought through properly.

I spent a long time reading other reviews before I ordered, and I did believe that this would be the one that worked. Unfortunately, it wasn't.
