Only really suitable for small, young cats. The whole thing was quite wobbly, the hidey-hole is way too small even for our little cat, and he struggles to climb up from the second level to the third and fourth due to there being no logical way up - he would have to cling onto the side and hoist himself up. With a bit of DIY we got it to be suitable for him. The best part about the tree is the 'bowl' section - we didn't think he'd like it - and the scratching posts on the bottom which are brilliant for play time. Plus it is huge so thats a plus. Wouldn't not recommend it to someone, but there are better out there for the same price.
