Earth and Moon

What Earth and Moon Is — Honestly

Earth and Moon presents themselves with confident, high-energy marketing language — "nature's doctor in your own home," "50,000 skeptics turned believers," "ungrounded humans burn out." GroundingMatrix is going to give you a more measured framing than that, because we think you deserve the accurate picture rather than the amplified one — and because the accurate picture is genuinely good enough to warrant covering this brand without the embellishment.

Earth and Moon is a US-based grounding brand that has served over 50,000 customers, accumulated 5,000+ reviews at a 4.7 average, built a two-product core range around a distinctive conductive leatherette mat and an organic cotton silver thread sheet, and backed every purchase with a 100-day money-back guarantee. They include an outlet tester and safety adapter with every order — a practice GroundingMatrix considers a meaningful quality signal and one that many competing brands don't match. Their grounding science page references peer-reviewed research rather than making unsourced claims. And they ship globally with international reach across the Americas, Europe, Asia, and Australasia.

That's the honest case for Earth and Moon. GroundingMatrix covers them in our index on those merits — with the standard transparency notes about material specification depth and the honest caveat that their marketing language consistently runs further than the underlying evidence justifies. The products are real and well-reviewed. The claims around them deserve more nuance than the homepage provides.

The Conductive Leatherette Mat — The Most Distinctive Product in the Range

Earth and Moon's flagship mat uses what they describe as "soft, durable leatherette" — a synthetic polyurethane material described as nontoxic, vegan, eco-conscious, and highly conductive. GroundingMatrix covers the product in detail on its product page, but the material distinction is worth establishing at the brand level: this isn't the same carbon-coated vegan leather used in the GroundLuxe or Hooga Grounding Mat, and it's not the carbon-compound or stainless-steel-fibre material used in most other products in the GroundingMatrix mat index. It's a conductive polyurethane leatherette — a material class with genuine advantages (soft feel, flexible, vegan, non-toxic) and the same surface-conductivity considerations that apply to any coated or surface-treated conductive material.

GroundingMatrix's standard material transparency note applies: Earth and Moon doesn't disclose the specific conductive element or concentration within the leatherette material at the level of specificity that the highest-scoring brands in our index provide. "Highly conductive" and "eco-conscious synthetic polyurethane" is more information than some brands offer and less than others. Buyers who want exact conductive element specification will need to contact Earth and Moon directly — GroundingMatrix would encourage that inquiry before purchase for buyers to whom material specification matters most.

The Organic Cotton Silver Thread Sheet

Earth and Moon's second core product is an organic cotton grounding sheet using pure silver fibre — the same material class used by Rowland Earthing and BareEarth. GroundingMatrix covers the silver oxidation consideration that applies to all silver-thread sheets in our silver oxidation glossary entry — the short version being that silver thread requires precise care to maintain conductivity over time, and that Earth and Moon buyers should follow the same guidance that applies to any silver-thread sheet: no bleach, no fabric softener, gentle washing, and timing body products away from direct sheet contact.

The organic cotton certification is a positive signal — the same distinction GroundingMatrix highlights for Rowland Earthing's certified organic cotton construction. Earth and Moon doesn't specify the silver concentration percentage at the brand level, which is the same material transparency gap noted for the mat. For buyers comparing silver-thread sheets specifically, the specification depth available from BareEarth (10% silver disclosed) or Rowland Earthing (pure silver thread, third-party organic certification) allows more objective comparison than Earth and Moon's current disclosure level supports.

The 100-Day Guarantee and Outlet Tester Inclusion

Two things Earth and Moon does at the operational level that GroundingMatrix considers worth specifically acknowledging alongside the material transparency gaps.

The 100-day money-back guarantee is the equal of the longest in the GroundingMatrix index — matching the 100-day window that GroundingMatrix considers most aligned with what the grounding research says buyers actually need for fair evaluation. The peer-reviewed sleep and cortisol research most directly relevant to grounding sheet outcomes — covered in GroundingMatrix's Ghaly and Teplitz study breakdown — shows meaningful changes emerging over eight weeks of consistent use. A 100-day window gives buyers that full runway and then some. GroundingMatrix takes this commitment seriously as a signal of brand confidence in outcomes rather than a marketing afterthought.

Including an outlet tester and safety adapter in every order is the second operational decision GroundingMatrix commends. As covered across every product page in our index, an ungrounded outlet is the most common silent reason grounding products fail to deliver results. Brands that include the tester as standard — rather than selling it as a separate accessory — are making a buyer-first decision that prioritises setup success over accessory revenue. Earth and Moon makes that decision, and GroundingMatrix notes it accordingly.

A Note on Marketing Language

GroundingMatrix's editorial standard requires honesty about where a brand's communication goes further than the evidence supports, and Earth and Moon's homepage provides some examples worth flagging. "Nature's doctor in your own home" is marketing language rather than a description of what grounding is or does. "Ungrounded devices explode. Ungrounded humans burn out" is an analogy rather than a physiological claim. "50,000 skeptics turned believers" is a customer count presented as a conversion story.

None of this makes the products not work. The grounding mechanism is real, the research is genuine, and the verified customer outcomes are consistent with what GroundingMatrix sees across the index. What it means is that Earth and Moon's marketing takes the established grounding evidence and presents it at a higher temperature than the peer-reviewed research directly supports — which is common across the grounding brand space and which GroundingMatrix consistently notes rather than endorsing or condemning.

Buyers who want the accurate evidence base behind grounding should read GroundingMatrix's Science Index and the study breakdown posts rather than relying on any brand's homepage for their scientific education — including Earth and Moon's, which presents the research more confidently than its sample sizes and study designs technically justify.
