Observations:
1. These are your in-laws. Chances are they don't have a litter of kids
wreaking havoc, so the chances of catastrophic abuse is minimal.
2. To ally your concerns, add to the project the installation of nylon
feet/sliders on the furniture legs.

Make sure you have a few extra tiles in the closet. Just in case.


I put them down for my father inlaw without problem.
