Really happy with the purchase of this cat condo, and the cats love it.  Although it say 106", the very top is VERY adjustable up and down.  To make it easier for the cats and for more places for them to perch, we left the upper two ladders off.  With the ladders on, its hard for them to get from one place to another.  I was very pleased with the construction and how sturdy the cat condo was.  I would highly recommend it to anyone.
