EMF Protection Foam Upgrade

Essentia EMF Protection™: The Only One Built Into the Mattress

Dark field microscopy shows blood cells forming clusters (Rouleau formation) after just minutes of EMF exposure, restricting how freely oxygen moves through the blood. That flow matters for the cell recovery your body relies on during sleep. Essentia's EMF Protection Foam creates a natural frequency that returns cells to their normal, free-flowing state within seconds. Can only be added at time of purchase.

Dave Asprey Upgrade includes a higher concentration of informed quartz and a graphene-infused organic cotton cover for enhanced energy flow and amplified protection.

Why the REM9: Two Exclusive Advantages

01

Accelerated Recovery, only on the REM9

The Accelerated Recovery foam formula is engineered for elasticity and rebound, with a more rubberized structure than our standard foam. Positioned beneath the Beyond Latex Active surface layer, it works in contrast to it. While Beyond Latex molds and contours to your body, Accelerated Recovery reacts and adapts more quickly beneath it, rebounding as you move rather than holding a fixed shape. This accelerated adaptability is what keeps you from sinking into or getting locked into one position, supporting fewer interruptions and longer stretches in REM and Deep Sleep that define the REM9.

This responsiveness is also a product of density. Essentia foams are built at 5 to 6.25 lb density, notably higher than the 1.5 to 4 lb density used industry-wide. Higher-density foam holds its structure and support over time rather than breaking down, which is also why Essentia mattresses are heavier than most, a direct result of using more high-density material, not less.

The result is fewer sleep interruptions and longer, more consistent stretches in REM and Deep Sleep, the stages where physical recovery and cognitive restoration actually happen.

02

The Most Advanced Cooling Technology

Both the Classic REM5 and Dormeuse REM9 feature Beyond Latex Active foam, but the REM9 goes further with a higher concentration of activated quartz. Active Cooling performance is deeper on the REM9, up to 9 degrees cooler over an 8-hour cycle, compared to up to 5 degrees on the REM5. Your body is not a static system. Night to night, your thermal needs change based on age, hormones, stress load, training intensity, nervous system state, and even where you are in your monthly cycle. The goal of sleep cooling, then, is simple but specific: support the body's natural release of heat without stimulating it in the process.

Essentia is the only mattress to use activated quartz for Active Cooling, achieving this without phase-changing chemicals or manual refrigeration, both of which work against your body's natural processes.

When this is paired with the exclusive Accelerated Recovery foam, the REM9 becomes the strongest option for anyone prioritizing recovery depth and temperature regulation.

Why the REM9 over the REM5

Feature	Classic REM5 Active	Dormeuse REM9 Active
Beyond Latex® Active foam	Yes	Yes
Activated quartz	Standard concentration	Higher concentration
Accelerated Recovery foam	Not included	Exclusive to REM9
Active Cooling	Up to 5 degrees cooler over 8-hour cycle	Up to 9 degrees cooler over 8-hour cycle
Feel	Responsive support	Softest, plushest feel in the lineup, with firm supportive feel underneath
Best suited for	Sleepers wanting Essentia's core performance foam	Sleepers prioritizing maximum recovery depth and temperature regulation
EMF Protection Foam™	Available as upgrade	Available as upgrade

Both the REM5 and REM9 use Beyond Latex Active foam, infused with finely milled quartz built directly into the foam's structure. This mineral composition supports breathability and thermal regulation. The REM9 is engineered with a higher concentration of activated quartz, which allows it to reach up to 9 degrees cooler over an 8-hour cycle, compared to up to 5 degrees on the REM5.

Dormeuse REM9 Active Organic Mattress

8 Key Elements of Regenerative Sleep

The Dormeuse REM9 Active is the only Essentia mattress engineered around all 8 key elements of regenerative sleep. A Beyond Latex Active surface sits over a high-rebound Accelerated Recovery layer and a GOLS certified organic latex core, so the mattress reacts as you move, runs cooler than your body, and holds your spine in alignment through every cycle of the night.

Accelerated Recovery

The Dormeuse REM9 Active is the only Essentia mattress built with Accelerated Recovery, a high-rebound foam layer that sits beneath the Beyond Latex Active surface. It reacts and readjusts faster than standard foam, pushing back as you move so a change in position won't wake you. This accelerated adaptability means fewer sleep interruptions and more uninterrupted time in Deep Sleep and REM, the cycles your body relies on to heal and recover.

Active Cooling

The REM9's Beyond Latex organic foam is infused with a higher concentration of activated quartz than any other Essentia mattress, giving it the deepest cooling in the lineup. It draws heat away from the sleep surface and through the mattress, keeping the REM9 up to 9 degrees cooler than your internal body temperature throughout an 8-hour sleep cycle. This encourages micro-hibernation and helps you stay asleep instead of waking up overheated.

Allergy Friendly

The Dormeuse REM9 Active is built without wool or fiber batting, so there's no haven for dust mites. Its Beyond Latex organic foam is naturally impervious to dust mites and contains no allergenic proteins, making it safe for latex allergy sufferers. This was tested and reported by Dr. Robert G. Hamilton of the Johns Hopkins School of Medicine, so you can rest in a cleaner sleep environment with fewer allergens working against you.

Enhanced Posture Support

Beneath the REM9's plush Beyond Latex Active surface sits a GOLS certified organic latex support core that keeps your spine properly aligned all night. The Beyond Latex formula eliminates negative space and molds to your body for consistent, full-body support, so even Essentia's softest mattress still relieves back pain rather than letting you sink out of alignment.

Optimized Oxygen

The REM9's Beyond Latex organic foam evenly distributes your body weight across the mattress surface, eliminating the pressure points that cause numbness and soreness. With weight spread evenly, oxygen and blood flow more freely, helping your brain stay in the deep, restorative sleep cycles that fragmented, pressure-interrupted sleep would otherwise cut short.

Certified Organic

Every Dormeuse REM9 Active is built from the highest quality, ethically sourced organic materials, free of the VOCs and petrochemicals found in memory foam. It's GOLS and GOTS certified, and manufactured in Essentia's own GOLS and GOTS certified organic factory, so your body can focus on recovery instead of processing what it's sleeping on.

Mold Protection

The REM9's Beyond Latex organic foam uses Essentia's proprietary, high-acidity mold protection formula, made from essential oils infused directly into the foam. This creates an environment that actively hinders mold growth on the mattress itself, protecting against the chronic fatigue, allergies, and other issues mold exposure can cause.

EMF Protection Foam

Available as an upgrade on the Dormeuse REM9 Active, Essentia EMF Protection™ infuses informed quartz directly into the foam. Research using dark-field microscopy has shown blood cells tend to cluster when exposed to electromagnetic fields; the informed quartz becomes the dominant, stabilizing wave pattern in your sleep surface, giving your blood cells something more natural to respond to instead of ambient EMF signals. Essentia is the only mattress brand to build EMF protection into the mattress itself, rather than relying on an external shielding product.

stop the invisible disruption

EMF Protection for
Truly Restorative Sleep

Every phone, router, and power line in your home emits low-level EMFs that never fully switch off. This constant exposure causes blood cells to clump together in a pattern called Rouleau formation, restricting the oxygen flow your body relies on for deep, restorative sleep.

Choosing to add Essentia's EMF Protection Foam™ upgrade integrates informed quartz directly into your Dormeuse REM9, countering these disruptive frequencies right where you sleep. No external shielding blanket or canopy required, just protection built into your mattress.

built for your health, not just your sleep

Organic Materials You Can Actually Trust

The Dormeuse REM9 is held to Essentia's Beyond Organic® Standard, our company-wide commitment to non-toxic, VOC-free materials on every mattress we make. It's vegan and cruelty-free, contains no toxic flame retardants, and is naturally allergen and dust-mite free.

You won't find any polyurethanes here. Our proprietary mold protection formula, made from high-acidity essential oils infused directly into the latex and Beyond Latex foam, keeps your mattress cleaner without synthetic treatments, so you can sleep easy knowing every layer beneath you is working for your health.

How Does the Dormeuse REM9 Active feel?

The Dormeuse REM9 Active is unique as it features 2 of Essentia’s most advanced foam formulas: Active and Accelerated Recovery that can only be described as soft and cozy, but still somehow extremely supportive.

This high-density support system will automatically adjust or adapt to your sleeping position, so you'll experience optimal spinal alignment and pressure relief wether you sleep on your back, side, or stomach. The Accelerated Recovery foam will ensure reduced sleep interruptions as the mattress will basically react to your movements before you ever realize they happened.

The comfort of this mattress can be described as a medium-soft feel with a medium-firm support.

It's generally very hard to describe a foam mattress as firm or soft, which may come as a shock to you as the mattress industry relies on these terms so deeply. But it’s important to note that the optimal performance of a foam mattress does rely on it being on a firm and sturdy foundation.

Why is this important? Foam contours to your body, and if you are using a weak bed frame or a box spring it can potentially change the overall feel and performance of the mattress in regards to contour and support.

What Foundation Can I Use?

Your new Essentia mattress works perfectly on our No Flex foundation or Rize adjustable foundation.

You may also use your Essentia on a slatted bed base. Should you opt for slats, ensure that each slat is completely flat and firm (no bowing upwards or plastic parts) and that there are no more than 3 inches of space in between each slat.

Please ensure that you are using a proper foundation option with your Essentia as an improper foundation may affect your warranty. A box spring should not be used unless the inside does not contain actual springs but is a firm surface.

No Toxic Flame Retardants

Picking a non-toxic flame retardant that did not affect the performance of our mattresses was of utmost importance. This is why we use Kevlar fabric. While it is the most expensive flame retardant option, it allows us to use a non-toxic fabric that does not go against our Beyond Organic values.

Essentia is proud to have an allergy friendly and vegan mattress free of wool or wool padding.

Think of the kevlar fabric much like a sock that we place the mattress in and then sew up on the open end, this is a fabric layer you will find under the GOTS certified organic removable cover. There are no toxic flame retardants sprayed or used in our GOLS certified organic factory.

How do Mattresses Ship?

As the leaders in environmental manufacturing, this means that we also had to prioritize a way to ship our dense mattresses to reduce our carbon footprint. In order to do this, we have developed a specially fitted roll-pack machine to compress and roll our mattresses into boxes that take up 75% less space on the delivery truck.

All mattresses are compressed and rolled, shipped in a tall, skinny box. In fact, you may confuse it for a carpet if not for the weight. We offer FedEx delivery to your door on every order to the contiguous United States.

If you would like a team to set up your new mattress, you do have the option to purchase Ryder In-Home Delivery with or without old mattress removal. The Ryder In-Home Delivery upgrade is $299 per mattress and foundation, and the Ryder team will call you to schedule a delivery day and timeframe for your setup. Simply choose this option at checkout if you would like to set up service.

Please note that we must have a full shipping address in order to ship your order. We cannot deliver to post office boxes (PO Boxes) or APOs.

Care for Your Mattress

- Your Essentia mattress will never be flipped, there is only one surface to sleep on. The proper sleep surface is the top of the mattress with the beige organic cotton cover.

- Should you choose to do so, you can rotate your mattress once a year but this is not a required step.

-We do not recommend the use of a waterproof cover with our mattresses unless the situation calls for it such as a small child learning to potty train, worries about an animal having an accident, or any such situation that may result in the bed being soiled.

- In the event there is a small accident or spill on your mattress don’t fret! Your first step will be to absorb as much of the excess liquid as possible with a dry cloth. If you feel the need for surface cleaning we do not recommend the use of any chemical cleaners. You can choose to use essential oils in water such as tea tree and lavender. Allow the surface to fully air dry before putting the covers back on.

- The GOTS certified organic cotton cover is machine washable. As organic cotton can be affected by heat please only wash in cold water using a mild eco-friendly detergent. Allow to air dry.

- Do not use bleach or other chemical cleaners on your mattress.

- You should be using your mattress on a flat, rigid, breathable surface. The mattress should not be used on the floor.

Labels on Your Mattress

When you receive your mattress, there will be a few labels affixed to it. The first you will notice is the tag or flag on the corner of the foot of the mattress that will show your model name.

If you chose to upgrade your foam to our EMF protection foam, you will also find a tag that confirms this.

At the head of the mattress, where you will also find the head of the zipper, will be the law labels, GOTS certified organic label and the Beyond Organic label. Here at Essentia, we do not use any synthetic foams or polyurethane foams. There are no chemical adhesives used to construct our mattresses, we do use a solvent-free, GreenGuard Gold certified, water-based adhesive where needed. For mattresses shipped to the United States, you will see noted the Kevlar fabric non-toxic fire barrier. We do not use any chemical flame retardant or spray any chemicals in our factory.

20 Year Mattress Warranty

Essentia’s mattresses feature a 20-year prorated warranty! To demonstrate the durability of Essentia’s high-quality mattresses, a 250lb hexagonal shape roller passes over the mattress 200,000 times, which simulates 10 years of use. What was found is that the Essentia mattress experienced a loss of less than a quarter inch of its original height at the 10-year mark. Based on these results, it’s safe to say you can expect your Essentia to stand the test time, with the added security of your twenty-year prorated warranty.

Your mattress comes with a 20 year limited warranty. We warranty the first 3 years of your mattress in full! This means should there be any issues that fall under the terms of the warranty, you will get a new mattress and we cover the full replacement value.
