Before buying a grounding mattress pad, check seven things on the product page: the conductive material, whether it grounds through your fitted sheet, true mattress sizes, thickness, a safety resistor in the cord, what ships in the box, and the trial and warranty. If any of the seven is missing from the page, assume the answer is no.
The seven-point checklist
- Conductive material, stated as a percentage. "Conductive" alone is not a specification. Earthbound lists 75% breathable vegan leatherette and 25% conductive carbon fiber–graphene blend.
- Grounds through your fitted sheet. If you plan to keep your bedding, the page must say so. Earthbound: works through your fitted sheet using Near Field™ Earthing.
- True mattress sizes. Half and full "universal" strips with straps are fine for one sleeper; a shared King needs a King. Earthbound lists Split/Single, Twin, Twin XL, Full, Queen, King and California King with dimensions.
- Thickness. Anything under about 2 mm disappears under a fitted sheet. Earthbound: 1.85 mm.
- A resistor in the cord. 100k ohm is the figure Earthbound and Hooga list; it is the safety barrier between you and the wiring. Earthing.com and GroundingWell list resistors too.
- What is in the box. Cord, region-specific adapter and an outlet tester at minimum. Earthbound includes a free outlet tester with every order; Hooga sells its tester separately.
- Trial and warranty, in days and years. 45 days, 60 days or 90 nights for the trial; and whether a warranty is stated at all. Earthbound: 90 nights and a lifetime warranty.
Three things that are not on the checklist
- Star rating. Every brand shows 4.5 or higher. It separates nothing.
- Customer counts. Several brands show different figures on different pages of their own site.
- Benefit lists. Grounding research applies to every working grounding product; a longer benefit grid does not mean a better pad. Read the studies once and then compare specifications.

After it arrives
Test the outlet before the first night, lay the pad under your fitted sheet, plug in, and give it 30 consistent nights. If you want to see the connection, a multimeter on AC volts shows your body voltage dropping when you lie down; Earthbound publishes its readings on the earthing test results page.
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
What is a grounding mattress pad?
A thin conductive surface sized to your mattress that connects to the ground port of a wall outlet so your body stays electrically connected to the earth while you sleep. Earthbound's is carbon fiber and goes under your fitted sheet.
Does a grounding mattress pad go under or over the fitted sheet?
Earthbound's goes under and grounds through the sheet. Some other brands' carbon covers go over or under and expect skin contact; check the page.
What size grounding mattress pad do I need?
Match your mattress: Twin 30"×75", Twin XL 38"×80", Full 54"×75", Queen 60"×80", King 76"×80", California King 72"×84" on Earthbound's size list. Split/Single 28"×70" covers one side of a bed.
Is a grounding mattress pad safe?
The cord connects only to the outlet's ground port and, on Earthbound's pad, includes a built-in 100k ohm resistor. No electricity flows into the pad. Test the outlet with the included tester first, and ask a physician if you have an implanted electronic device.
How long does a grounding mattress pad last?
Carbon fiber will not oxidize or lose conductivity over time, which is why Earthbound describes the pad as a buy-it-once product backed by a lifetime warranty. Silver sheets, by contrast, carry two-to-three-year lifespan statements.
