great idea to save money
We have had this cat tree for over 8 years. This is compared to our first tree that only lasted about 3 years. I am not good at putting together furniture, etc, but I can do this. We have purchased several of the column Q parts over the years, and our tree looks practically brand new. I don't know why other companies have not thought of this other than they want to make more money. This also helps the planet reduce waste.
