Super easy to put together and has an understated look that blends in well with modern decor! Doesn't stand out in my house as a "cat tree". My cat is on the large side (11 lbs) and she was a bit apprehensive to use the smaller steps but after some coaxing with some treats she's now a pro. 
Top shelf is at eye level which is nice and taller than most cat trees. Love this thing.
