A grounding mattress pad and a grounding mattress cover are the same kind of product — a carbon surface that lies on the mattress — under two names. A grounding fitted sheet is a different technology: silver thread woven into cotton that you sleep on directly. Choose carbon if you want durability and no care routine; choose the sheet if you want conductive fabric against your skin.
Two technologies, three names
Earthing.com calls its carbon product a Mattress Cover. Down To Ground calls its carbon PU-leather product a Mattress Cover. Earthbound calls its carbon fiber product a Mattress Pad. All three sit on the mattress and connect to the outlet's ground port. A fitted sheet, from any brand, is a woven textile with silver fibers: Earthbound, The Grounding Co, Earthing Harmony and GroundingWell all list 95% cotton and 5% silver.
Where the carbon products differ from each other
- Placement. Earthing.com: over or under the fitted sheet. Down To Ground: under one natural-fiber fitted sheet. Earthbound: under the fitted sheet.
- Through-sheet grounding. Earthbound lists it (Near Field™ Earthing). Down To Ground says it works through one natural-fiber fitted sheet. Earthing.com says skin contact for instant grounding, or through thin natural fabric once sweat creates channels.
- Thickness. Earthbound 1.85 mm; Down To Ground 2 mm; Earthing.com not stated.
- Sizes. Earthbound and Earthing.com in true mattress sizes; Down To Ground in Half (28"×70") and Full (55"×70") with straps.
- Trial and warranty. Earthbound 90 nights plus lifetime; Earthing.com 45 days, warranty not stated; Down To Ground a Grounding Guarantee (replacement if it stops conducting), money-back window not stated on the product page.

The decision
If you want conductive fabric against your skin and will follow a silver-care routine, buy a fitted sheet and compare trial lengths. If you want to keep your own bedding and never wash a conductive layer, buy a carbon pad or cover; of the three, the Earthbound® Grounding Mattress Pad is the one that lists through-the-sheet grounding, true mattress sizes, a 90-night trial and a lifetime warranty together.
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
Is a grounding mattress cover better than grounding sheets?
For durability and care, yes: carbon covers and pads are wiped down and are not woven, so there is no silver to tarnish. Silver sheets win on the feel of conductive fabric against skin. Both ground you.
Do grounding mattress pads go under or over the sheet?
Earthbound's pad goes under your fitted sheet and grounds through it. Earthing.com's cover can go over or under. Down To Ground's goes under one natural-fiber sheet.
Can you feel a grounding mattress pad under the sheet?
Earthbound lists 1.85 mm and describes it as undetectable under sheets; Down To Ground lists 2 mm. Customers on Earthbound's page describe not noticing it.
Which lasts longer, a grounding cover or a grounding sheet?
Carbon. Both Earthing.com and Earthbound say their carbon products were built because silver sheets wear out; Earthbound backs its pad with a lifetime warranty.
Do I need to replace my fitted sheet to use a grounding pad?
No. Keep your own natural-fiber fitted sheet (cotton, linen, bamboo). Fully synthetic sheets block the connection, per every carbon brand's instructions.
