This cat tree could have a better design so the cat can easily go up and down the tiers.  Like a previous review, we had to take out the top box and top tier so that my cat can go up and down easily.  The two tiers between the top box is designed so that cat must jump down from the back and onto the box and then down.  Not so easy to do with a bigger cat.  The cat tree is also a little wobbly, especially when my cat goes to the tier on top of the top box.   It's great for the price if you are willing to compromise, but probably a product that I would not buy again.  This cat tree only needs to last me two years.  Hopefully it will...
