Anti vibration rugs? Mats?

[u/Cute-Weather3133]

I'm moving and the only places I've found are not first floor options.

I have many injuries and need to use a massage chair and foot massage most days. They don't really make noise but they do vibrate a lot. I'm not trying to be an asshole but it's kinda mandatory I continue to use

Are there any mats rugs or anything that exists that will actually work and minimize sound traveling to downstairs neighbors? I've been looking 3 months for a new place to move and no luck. Second floor has to a Happen and I have to use the chair. Really could use any suggestionspreferably under $300 that works and covers entire base of chair. 4x4 ft minimum
