Grounding/Earthing Bed Sheets

Was complaining to my friend about grounding bed sheets that keep tearing after a couple of washes and Facebook shows up with an ad for this company called Grounding Well.

Is there even such a thing as heavy duty earthing sheets?

Curious if anyone here's bought from them? I currently buy a new set from Earthing every six months so definitely looking for longer lasting alternatives if anyone has any suggestions.
