I do not know if I can recommend this cat tree… My cats love it and used it right away (even when we were in the middle of building it). 
This tree is very wobbly. The top two perches wobble so much when my cats get on them that I am afraid they are going to fall off. We took the top two perches off to see what is wrong with them, and the washer inside the poles and the bolt used do not match (the washer is about 1mm larger than the bolt) so the bolt does not fit well which is causing the two perches to wobble so much. So you will probably need to buy different bolts…
The sides are high which my cats love. 
So my cats love it, but we humans do not love it hence the 3 stars.
