A Larger Mat Than Most — and Why That Size Matters

Most universal grounding mats sit in the 10" × 27" to 16" × 32" range — sized for under-desk foot contact or couch use with legs positioned carefully. The Earth and Moon Grounding Mat at 60cm × 90cm (approximately 24" × 35") is in the large mat category — closer to the Terra Earthing Mat's floor format than to a compact desk mat. That size difference is practical rather than cosmetic.

A 60cm × 90cm mat accommodates both feet side by side with room for the lower legs, making it useful for desk work without requiring careful positioning. It's large enough to lie down on for the lower half of the body during a post-exercise recovery session or a floor relaxation period. It works across a sofa cushion with enough surface to ground both legs and a forearm simultaneously. And it's the size that stays in contact through normal repositioning during use rather than requiring periodic nudging back into position.

GroundingMatrix covers why mat size affects consistency of grounding contact in our mat vs sheet guide — the short version being that a larger contact surface reduces the positioning discipline required to stay grounded during natural movement. For buyers choosing between a compact desk mat and a larger format, the Earth and Moon mat sits clearly in the larger, more versatile category.

The Conductive Leatherette Surface — What It Feels Like and What You Need to Know

The Earth and Moon mat uses a soft synthetic polyurethane leatherette surface — described by Earth and Moon as nontoxic, vegan, and eco-conscious. GroundingMatrix covered the material distinction on the Earth and Moon brand page: this is a different base material from the carbon-coated vegan leather used in the GroundLuxe and Hooga Grounding Mat, and different again from the carbon compound or stainless steel fibre constructions used across most of the GroundingMatrix index.

The practical experience of the leatherette surface, per verified buyer reports: soft to the touch, flexible enough to roll, and warm against the skin rather than the cool initial contact of firmer synthetic surfaces. The conductivity is surface-based — the leatherette material itself is the conductive layer — which means care requirements apply. Wipe clean with a damp cloth and mild soap rather than machine washing. Avoid applying lotions, oils, or creams to skin immediately before contact — these build up on the conductive surface over time and reduce conductivity. A consistent weekly wipe-down during regular use maintains both hygiene and conductivity effectively.

One verified buyer — Pamela — specifically tested the mat with a multimeter before writing their review: "I tested the mat using a multimeter and I got a reading of 47 volts before touching the mat and then 0.21 when touching the mat." That's the body voltage drop that confirms the circuit is completing — from 47V to 0.21V represents a near-total equalisation to earth potential that's exactly what effective grounding produces. GroundingMatrix considers buyer-initiated multimeter verification among the most credible confirmations of product conductivity available, and Pamela's specific numbers are precisely in the range the grounding literature predicts for an effective grounding connection in a typical indoor environment.

TrueGround™ — Earth and Moon's Safety Protocol

Earth and Moon uses the term "TrueGround™" to describe their approach to grounding product safety — covering three specific inclusions that GroundingMatrix considers worth flagging as positive operational decisions.

First: the outlet tester included with every order. GroundingMatrix covers why this matters on every product page in the index — an ungrounded outlet is the most common silent reason grounding products fail to deliver results, and including the tester in the box removes the barrier to the pre-setup verification step that every buyer should complete. Earth and Moon making this standard rather than an upsell reflects a buyer-first approach GroundingMatrix commends consistently.

Second: the 100K ohm safety resistor built into the grounding cord. GroundingMatrix covers this in the safety adapter glossary entry — the resistor limits any potential fault current to a level far below anything harmful, in the unlikely event of unusual electrical conditions in the building's wiring. Its presence here is confirmed and documented by Earth and Moon, which is the disclosure standard GroundingMatrix considers necessary for any grounding product.

Third: the 15-foot cord length. Not a safety feature specifically, but a practical one — 15 feet is the de facto standard across the GroundingMatrix mat index for good reason, providing sufficient reach from a grounded outlet to a desk, couch, or floor position in most room configurations.

The Reviews — What 215 Verified Buyers Actually Said

GroundingMatrix reviews buyer feedback as part of every product assessment. The Earth and Moon Grounding Mat's 215 reviews at 4.8 average with 100% recommendation rate is notable — zero two-star or one-star reviews at time of assessment is unusual at this review volume. The qualitative feedback pattern shows several consistent themes worth noting.

Sleep improvement shows up repeatedly and specifically. Val B.: "I've been using the grounding mat to sleep on every night and I have without a doubt been waking up feeling less achy and sleeping way harder." Valerie (video review): "The very first time I used it, much less aching, I got up more easily." Maria F.: "I used to wake up during the night maybe 1 or 2 times and sometimes found it hard to get back to sleep but honestly since using this earthing mat on the regular I hardly wake up in the night." This wake-up frequency pattern — from multiple per night to near-zero — appears across multiple independent reviews and aligns with the cortisol normalisation mechanism documented in the Ghaly and Teplitz research covered in GroundingMatrix's Science Index.

A review GroundingMatrix considers worth flagging specifically: Jazzi's review of a grandchild with Autism who uses the mat at school — "His teacher has mentioned that he seems calmer during the day when he uses it at his desk." This is consistent with grounding's autonomic nervous system regulatory effects covered in our anxiety and grounding guide, and the teacher's independent observation rather than the buyer's own perception adds a layer of credibility. GroundingMatrix presents it as a genuine individual report rather than a universal claim about grounding and Autism — individual experiences vary significantly and this is a single case.

The neuropathy buyer — AC, first review shown: "I am diabetic with neuropathy and am hopeful that the grounding pad will help with that." This is a first-day report rather than a long-term outcome review, but it represents a buyer profile — people managing diabetic neuropathy — for whom the anti-inflammatory and circulation-related mechanisms of grounding are most directly relevant. GroundingMatrix covers the chronic pain and inflammation context in our chronic pain glossary entry and always recommends consulting a qualified healthcare professional before using any wellness product alongside existing medical treatment.

Versatile Use — Five Ways to Get Value From This Mat

The 60cm × 90cm size creates a genuinely versatile product that's harder to pigeonhole into a single use case than a smaller desk-specific mat. GroundingMatrix identifies five distinct configurations where this mat's size works specifically in its favour.

Under-desk floor mat: Both feet side by side with room to shift positions naturally during a workday — the configuration that accumulates the most grounded hours for desk workers without any active management.

Bed mat alongside the mattress: Placed vertically alongside the lower portion of the mattress, this mat is large enough for feet and lower legs during sleep — an intermediate step between a desk mat and a full grounding mattress cover for buyers who want sleep grounding without full sheet investment.

Couch or chair mat: Draped across a couch cushion or over a recliner footrest, the size covers enough surface for both lower legs and allows the mat to stay in position through natural position shifts during an evening of TV or reading.

Floor yoga or stretch mat: Large enough for lying with the lower body in contact during stretching, meditation, or post-exercise recovery sessions — the same use case GroundingMatrix covers in our timing guide as the most mechanistically targeted window for recovery benefits.

Standing desk mat: For buyers who alternate between sitting and standing during the workday, the size accommodates standing use with bare feet across the full mat surface — a configuration that smaller desk mats can't support comfortably during extended standing periods.

The Lifetime Warranty — A Notable Commitment

Earth and Moon offers a lifetime warranty on the mat — the same term noted on the brand page comparison table and one of the strongest warranty commitments in the GroundingMatrix index alongside Earthbound's lifetime warranty on their carbon fibre products. GroundingMatrix notes a discrepancy between the guarantee periods stated on different pages — the product page lists "90-day money-back guarantee" while the brand page references 100 days. GroundingMatrix recommends buyers confirm the current return policy directly with Earth and Moon before purchasing to ensure they're working with the most current terms. The lifetime warranty on the product itself is separately stated and consistent across both pages.

Care Instructions

Wipe with a damp cloth and mild soap — do not machine wash, submerge, or use abrasive cleaners. Air dry completely before use. Avoid applying body lotions, oils, or creams to skin immediately before contact — these transfer to the leatherette surface and accumulate over time, reducing conductivity if not regularly cleaned. A consistent wipe-down every one to two weeks during regular use maintains both hygiene and conductivity. Store flat or rolled — avoid folding to prevent creasing the leatherette surface. Test conductivity with a multimeter or outlet tester periodically to confirm performance is maintained.

Step 1 — Test your outlet (use the included tester) Plug the included outlet tester into your wall socket before connecting anything else. Two amber lights confirms a properly grounded outlet. Any other reading means trying a different outlet or using a grounding rod. This step takes ten seconds and is the single most important check before any grounding session.Step 2 — Connect the cord to the mat Snap the grounding cord firmly onto the connector on the mat's edge. Press until it clicks securely — a loose connection is the most common cause of intermittent grounding performance that gets misread as product failure.Step 3 — Plug into the grounded outlet Insert the safety adapter into the ground port of your verified outlet. The 15-foot cord gives you flexible positioning from most standard outlet locations in a typical room.Step 4 — Place the mat in your chosen configuration Under the desk for feet, alongside your mattress for sleep, across the couch for evening use, or flat on the floor for recovery sessions. The 60cm × 90cm size gives you options that smaller mats don't.Step 5 — Make direct skin contact Bare feet, hands, or forearms directly on the leatherette surface. Thin cotton socks allow some conductivity once foot moisture builds — fully synthetic socks block it. Direct skin contact is always the most immediate and reliable grounding method.Step 6 — Use daily for at least 30 minutes — build from there GroundingMatrix recommends committing to 60 days of consistent daily use before evaluating results. The mat's versatility makes building the habit practical — it moves with you between desk, couch, and floor without any reconfiguration. The routine building guide on GroundingMatrix covers how to make this kind of daily practice automatic rather than effortful.
