Why not just buy those sticky felt pads for the chair legs?
Available at any hardware store in various sizes. Using half
tennis balls sounds a bit silly to me. Never seen that done in
any classroom or house with hardwood floors.
Â*Â* because the felt pads don't stay on.

Buy decent quality pads and clean the bottom face of the legs before
application will see them stay on for a long time. I did some 6 years
ago and only now I notice a couple have become dislodged.


Some time ago the school retrofitted all the chairs in the classrooms
with this "snap cap & slide"

It wasn't long before the plastic snaps started to break, resulting in a
wobbly chair. (never under estimate the power of a 7th grader to break
anything labeled "unbreakable ;-)

Also there are many available things that try to address the issue
(see https://www.schoolfix.com/chair-desk-glides.html )

but the consensus among actual classroom teachers around here seems to
be the tennis ball is best.
