Why this site exists
I started testing grounding sheets because I could not find a single review that was honest about what they do and do not do. Half the internet treats earthing like a miracle cure. The other half calls it a total scam. The truth sits in between, and that gap is where I write.
I have slept on six different grounding sheets since 2021, washed them until the conductivity faded, tested outlets with a cheap plug-in tester, and read the actual studies instead of quoting a headline. When a sheet is good, I say so. When it is overpriced fabric with a cord, I say that too.
How I test
Every product goes through the same checks: is the conductive fiber stainless steel or silver that oxidizes, does it hold a real connection with a ground tester, how it feels under a fitted sheet across a few weeks, and what the trial and warranty actually cover. Health claims get held to the research, not the sales page.
My rule on evidence
Grounding has a small body of real studies, mostly on sleep and relaxation, and mostly early-stage. I cite those by name and I never claim a sheet treats or cures anything. If the evidence is thin, you will read that here first.
Affiliate note
Some links here go to retailers. That never changes a verdict. The recommendation is the same one I would give a friend who asked what to buy.
