Earthing.com: The Original Brand, and Why That Matters Less Than You'd Think

Clint Ober is the reason grounding sheets exist as a consumer category. In the late 1990s and early 2000s, he developed and patented the first widely-marketed conductive bedding products. His company, Earthing.com, held the primary patents on conductive earthing sheets for years. The Earthing book and movie largely shaped how the public learned about grounding therapy.

If you're looking at grounding products, Earthing.com is the founder brand. That's a real thing. Whether it's the best brand to buy from in 2026 is a different question, and the honest answer is more complicated than the heritage suggests.

This is an honest look at what Earthing.com offers today, what they used to offer, what changed, and how to think about whether the original brand is still the right choice.

What changed in 2019

For many years, Earthing.com sold silver-thread fitted grounding sheets as their flagship product. The patent on conductive earthing sheets expired in 2019. Rather than re-engineer their product line to compete in a now-open market, Earthing.com discontinued their silver-thread sheets entirely.

This is genuinely important context that most affiliate sites don't surface clearly. If you go to Earthing.com today looking for the silver-thread fitted sheet they were famous for, you won't find it. The product they're best known for, the one referenced in the Earthing book and most older affiliate content, no longer exists in their catalog.

What they sell instead is a proprietary carbon-based grounding material called the Earthing Mattress Cover, available as a separate top layer that sits over or under your regular fitted sheet. Their reasoning, per their own marketing, is that customers wanted a sleep option that lasts longer than silver-thread sheets. The carbon material doesn't tarnish the way silver does, so the durability story is genuinely better.

The trade-off is that the form factor is different. You're not getting a fitted grounding sheet. You're getting a mattress cover that adds a separate conductive layer to your existing bedding setup.

What Earthing.com actually offers now

Their current grounding sleep product lineup focuses on the proprietary carbon material. Available products include:

The Earthing Mattress Cover Kit, which is the closest equivalent to their old fitted sheet. It's a carbon-based conductive layer that drapes over your mattress (or under your fitted sheet) at full mattress dimensions. Pricing varies by size but generally runs in the $200-300 range.

The Earthing Universal Mat Kit for desk or chair use. This is a smaller carbon mat with included cord and outlet tester. Around $40-60.

Pillow covers, sleep mats in single-person size, and various accessories. They also sell yoga mats, auto seat mats, body wraps, and other adjacent products.

What they don't sell anymore: silver-thread fitted grounding sheets in the form factor most other brands offer.

The patent and authenticity argument

Earthing.com (and the related brand Ultimate Longevity, which sells Ground Therapy products also designed by Clint Ober) push hard on an authenticity narrative. Their marketing explicitly calls competing brands "knock-offs" and warns buyers that products from Hooga, Earth and Moon, GroundLuxe, and others are "violating our patents" and are "ineffective" and possibly "dangerous."

This needs unpacking, because the framing is misleading.

The patents Earthing.com references, primarily Patent #7724491 (Method of Treating Inflammation and Autoimmune Disease) and Patent #7212392 (Personal Body Grounding System Instrumentation and Process), expired in 2019. After patent expiration, anyone can legally produce equivalent products. The "patent violation" claim is no longer accurate as a description of the current legal landscape.

The "ineffective" and "dangerous" claims about competitor products are also overstated. Independent testing of major brands like Hooga, Earth and Moon, GroundLuxe, and others shows their grounding sheets do exactly what they claim: drop body voltage to near zero when properly grounded. The competitor sheets aren't ineffective. They're functionally equivalent or, in some cases (like GroundLuxe's higher silver content), better at maintaining conductivity over time.

The "dangerous" claim is the most stretched. All major grounding brands include the standard 100k-ohm safety resistor in their cords. The technology is the same across the category. There's no documented pattern of competitor products being unsafe.

I'd treat Earthing.com's authenticity marketing as a competitive positioning effort rather than an objective assessment of competitor quality. The brand has a legitimate claim to founding the category, but that doesn't mean current competitors are knock-offs in any meaningful sense.

What buyers actually report

Reviews of Earthing.com's current carbon-based products are mixed, with patterns worth understanding.

Positive reports center on durability (the carbon material genuinely lasts longer than silver sheets), the connection to the founder narrative and the comprehensive customer support, and the integration with the broader Earthing ecosystem (the book, the movie, the research database).

Negative reports center on a few specific issues. The polyurethane top layer of some sleep mats has been described as feeling "plasticky" or sleep-warm compared to cotton sheets. One review notes the products feel like a 1990s industrial design that hasn't been modernized. Some users report the fit on modern thicker mattresses is awkward because the products were designed before deep-pocket mattresses became standard.

A particularly notable third-party perspective: Groundology, a UK-based grounding brand that previously distributed Earthing.com products in Europe, publicly discontinued the line. Their stated reason was concerns about the polyurethane sleep products, though they framed it diplomatically. When a former distributor publicly disowns the product line, that's worth noting.

Cost and value

Earthing.com's pricing tends to be at the higher end of the category. The Mattress Cover Kit at $200-300 is comparable to GroundLuxe's premium pricing but for a different product category (mattress cover vs fitted sheet).

The cost-of-ownership math is favorable for the carbon material specifically because it doesn't tarnish. A carbon mattress cover that lasts 4-5 years versus a silver sheet that lasts 2-3 years works out to lower per-month cost despite higher upfront pricing.

The trade-off, again, is the form factor. You're not buying a fitted sheet. You're buying a separate conductive layer that integrates with your existing bedding stack. For some users this is easier than replacing their fitted sheet. For others it's an extra layer of bedding complexity they didn't want.

Who this is right for

I'd recommend Earthing.com to buyers who specifically value the founder narrative and want to support the people who actually pioneered this category, regardless of whether their current products are strictly best-in-class.

I'd also recommend Earthing.com for buyers who specifically want non-tarnishing carbon-based grounding materials and prefer a mattress cover form factor over a fitted sheet. If you have nice cotton fitted sheets you don't want to give up, an Earthing Mattress Cover layered underneath maintains your existing bedding feel while adding the grounding layer.

I'd point someone elsewhere if they want a fitted grounding sheet specifically (Earthing.com doesn't make this anymore), if they're price-sensitive (the $200-300 range is mid-to-high), or if they prefer a more modern industrial design.

What about Ultimate Longevity / Ground Therapy?

Worth mentioning briefly because the brand confusion is real. Ultimate Longevity is a separate company that sells Ground Therapy products designed by Clint Ober. Same person, different company name, same proprietary carbon-based materials, similar product lineup. Ultimate Longevity essentially functions as a sister brand to Earthing.com.

If you're considering Earthing.com, Ultimate Longevity is worth a parallel look. Pricing is similar, products are similar, the trust framework is similar. The differences come down to specific product variations and which brand happens to have what you want in stock at any given time. Ultimate Longevity grounding sheet review

Where to buy

Earthing.com products are available primarily through their direct site at earthing.com. They have a limited Amazon presence under the Earthing brand, but the full product catalog and best pricing is on the direct site. Some products are also sold through wellness retailers and a few authorized distributors.

For Amazon shoppers specifically, the Earthing brand presence on Amazon is smaller and more focused on auto seat mats and a few specific accessories rather than the full sleep product lineup. For the complete Earthing catalog, direct from the brand is the right channel. Check the Earthing Elite Sleep Mat Kit on Amazon

Honest verdict

The original brand with a real founding story, but the product they sell today isn't quite the product they're famous for. Their silver-thread fitted sheet line was discontinued in 2019. What they sell now is a different format (carbon-based mattress covers) that has real durability advantages but represents an aesthetic and form-factor shift from what most people picture when they hear "grounding sheet."

If the founder story matters to you, if you want to support the category's pioneers, or if you specifically prefer carbon-based long-lasting materials in a mattress cover form factor, Earthing.com is the right choice. If you're looking for a modern fitted grounding sheet at competitive pricing with the kind of premium organic cotton feel that newer brands have refined, you're probably better served elsewhere.

The brand isn't bad. It's just no longer playing the same game as the rest of the category, and the marketing positioning that competitors are "knock-offs" is more legacy framing than current reality.
