TLDR; top shelf difficult to get to only if you don't angle it, which is the only complaint. Cats love it. Holds 32lb cat with ease. 20/10 purchase would buy again.
Long-form Review:
After about ~2months, give or take, I think I've seen enough to give a proper review.
I'm a grad student and adjunct so I saved up for about a year for this product.
This is a /very/ sturdy cat tree. My 32lb maine coon named Soup loves it. So do my two smaller, barn-bred cats. The issue of the top bed being hard to get to /is/ true. When built per instructions, my smaller cats were able to climb the front podium holding the bowl to get to the top (3rd image), but Soup is too big to be able to do that (2nd image). We settled with just angling the bed so he /could/ have the space to climb up and rest there, until he's kicked out by the tortie.
The bowl also does hold him very well, even if it does lean down slightly with his weight, but he is on the max end of the weight for his breed so that is specifically an US problem, not with the company. We say 'Soup is in his soup bowl' and he'll rest there when the top bed is taken. For some reason none of the cats like the back bowl, and they don't use the bottom cubby, though none of them have ever liked hidey holes, but they do eagerly climb, scratch, and play around the tree.
Objectively one of my favorite and best purchases in my lifetime! It is a cat tree Soup is able to use, which is all I really wanted. It came with all the parts, and while none of the parts were labelled per instructions, if you line them all up side by side you can figure it out pretty easy.
I do feel bad for whatever FedEx man had to deliver the boxes though. I live on the 2nd floor and that poor man had to heft up THREE, VERY HEAVY boxes. But I'm also a 5ft, 120lb woman. Many things are heavy for me. Dragging them in was my workout lmao.
