How to minimize washing machine

We will be installing our stacked washer dryer on the third floor, right above the living room. I am starting to get worried about vibrations from the machines ruining sheetrock seems or disturb tv viewing (god forbid!). Is there a product that anyone has used to minimize vibrations? I am picturing some sort of a platform packed with foam……or a very dense gel pad….
Thanks!
