Everything was great with the tower, it's super tall, which my cat loves, the cubby is large enough for my cat to comfortably sleep in, most cubbies are so tiny he never uses them but this one works perfect for him! And he is an extra long cat! It doesn't wobble around easily, at least not in my opinion. The only 2 things I would say are maybe a downfall are: the material is really thin, so I'm pretty sure it'll rip under a year or so, and it's so compact in design my cat doesn't really run up and down it during zoomies. So if you want it to give your cat more exercise than perhaps a more complexly built one. Other than that! I love it!
