A grounding mat connects your body to the earth while you sit, work or sleep. Research suggests that may support sleep quality, a normal cortisol rhythm, circulation, recovery and lower markers of inflammation and stress. Nine reported benefits follow with their sources, plus the difference between a desk mat and a mattress-sized pad.
Nine reported benefits
- Sleep quality. Park et al. (2025), a double-blind placebo-controlled study of a grounding mat, reported improved sleep quality scores.
- Total sleep time. Same study, measured by actigraphy.
- Insomnia severity. Same study.
- Daytime sleepiness. Same study.
- Stress. Same study, plus Ghaly and Teplitz (2004).
- Cortisol rhythm. Ghaly and Teplitz (2004).
- Blood viscosity and circulation. Chevalier et al. (2013); a 2019 study of grounded yoga mats reported reduced blood viscosity after exercise.
- Muscle soreness. Brown, Chevalier and Hill (2010).
- Nervous-system balance. Passi et al. (2017) and Sokal and Sokal (2011) describe reduced sympathetic activity and altered EEG signals during grounding.
All are small studies and the authors call for larger trials. Sources are linked on the 20-studies page.
Desk mat or bed pad: where the hours come from
A desk mat grounds you while bare skin touches it — typically a few hours at a computer. A mattress-sized pad grounds you for the six to eight hours you sleep. The 2025 study used six hours a day. If you can only buy one, the bed pad gives more grounded hours with no effort; the desk mat adds daytime hours on top.

How to tell it is working
Plug in the included outlet tester first. Then a multimeter on AC volts, one probe in hand and one on the ground port, before and after contact with the mat: the reading should drop sharply. Earthbound publishes its readings on the earthing test results page. Earthbound's mat page says most people notice a calmer, more focused baseline first, with deeper benefits building over consistent daily use.
Earthbound® Grounding Mattress Pad: the facts
Earthbound® Grounding Mattress Pad · From $119.99 · 4.8 | 1523 Reviews
- Made with conductive carbon fiber — inert, durable, resistant to oxidation.
- Connects to the Earth through any standard grounded wall outlet.
- Delivers 6 to 8 hours of passive grounding overnight, with no charging or maintenance.
- Works through your fitted sheet using proprietary Near Field™ Earthing technology.
- 1.85mm — undetectable under sheets
Sizes available to fit across all mattress sizes: Split Mattress - (28" x 70" in) · Single - (28" x 70" in) · Twin - (30" x 75" in) · Twin XL - (38" x 80" in) · Full - (54" x 75" in) · Queen - (60" x 80" in) · King - (76" x 80" in) · California King - (72" x 84" in)
Materials: 75% Breathable Vegan Leatherette, 25% Conductive Carbon Fiber - Graphene Blend. Color: Black with breathable perforations. The surface is a soft vegan leatherette blended with conductive carbon fiber, BPA- and phthalate-free and dermatologically tested, so it's comfortable even for the most sensitive skin.
Care Information: Solvent-free wipe-down, occasional cold wash when needed. Will not degrade like silver.
Do I need bare skin contact? No. Near Field Earthing works through a layer of fabric like your fitted sheet or pajamas, so you can sleep normally and still stay grounded.
How do I set it up? Lay the pad under your fitted sheet, plug the grounding cord into a grounded wall outlet, and sleep. No apps, no charging, nothing to remember. A region-specific outlet adapter is included. FREE Outlet Tester included with every order.
Will it last? Yes. It is built from conductive carbon fiber, which will not oxidize or lose conductivity over time, unlike silver-thread products. It is a buy-it-once product, backed by a lifetime warranty.
Is it safe? The grounding cord includes a built-in 100k ohm resistor for safety. No electricity flows into the pad. Only the Earth's free electrons.
90-Day Money-Back Guarantee: Ground consistently for 30 nights. If you are not satisfied, you get a full refund for up to 90 days after delivery.
Shipping: Orders ship within 24–48 hours. Shipping is free on orders over $50, which includes every mattress pad. We ship only from tryearthbound.com — never through Amazon or other marketplaces.
Frequently asked questions
Do grounding mats actually work?
They connect you to the earth through the outlet's ground, which you can verify with a multimeter. Research suggests effects on sleep, stress, cortisol, circulation and soreness; the studies are small and individual results vary.
When should you not use a grounding mat?
If you have an implanted electronic medical device, ask your physician first. If the outlet is not grounded, do not use it until it is fixed or you connect to a grounding rod. Earthbound's sheet page also suggests unplugging during thunderstorms.
What are the side effects of grounding mats?
Mild tingling or warmth in the first sessions and, for some sleepers, lighter sleep for a week or two while adjusting. See our side-effects article.
How do you know if your grounding mat is working?
Outlet tester first, then a multimeter: your body voltage should drop sharply when you touch the connected mat. Earthbound includes a free outlet tester with every order.
Is a grounding mat better than a grounding sheet?
For sleep, a mattress-sized carbon pad beats both a desk mat and a silver sheet on coverage and maintenance. For a desk, the mat is the right tool.
