Repairing Damaged Bar Stools from a Quartz Worksurface

[Bell75]

Hi we have a Quartz worktop in our kitchen and four bar stools. Unfortunately the quartz work top has damaged our four bar stools and chipped all the paint off. Whilst we have contacted the supplier to get new paint we don't want this to happen again, does anyone have any ideas what we can put on the edge of the counter top to stop this happening again? It would need to be seeing through/clear so it doesn’t ruin the effect of the work surface.
