A wonderful addition for our indoor young cat. The 12 year old doesn’t show much interest in it, but perhaps she’s happy when the 1-year-old is “up the tree” who is a 10 pound active cat.  It easily supports her weight with no wobble or fear of tipping.  As other reviewers said, make sure it is tightened at the top.  I played with her and put some cat morsels on the tiers to encourage her and learn it was “hers”.  Placing it by a window sill, there was another option of getting down as she learned to work the tiers. Other than 2 leaves coming off the first day, it’s been holding up very well.  It’s fun to be able to say hi and pet her at “eye level” when we walk by.  I wish I found it for her sooner!
