Those who can't imagine about furniture being rearranged every couple of years probably aren't married. If you are raising children you find that not only does furniture change but the entire purpose of some rooms tends to change over time.
Not that often for moving furniture - maybe once every 3-4 years max and the rooms - have not really changed in purpose.
Certainly if he can afford it - more power to him but I can fully understand the insanity of 20+ drops per room.--
