Overview

Most mattresses force you to choose one firmness. The EOS doesn't! This modular mattress is made of interchangeable layers that zip inside an organic cotton encasement, so you can choose your ideal firmness for comfort and support. Need a change? Swap layers any time, or even adjust one side without affecting the other. It’s a smarter, more sustainable way to fine-tune your mattress.

Don’t Compromise — Customize

Comfort You Control on Both Sides of the Bed

Adjust firmness on each side of the bed for your perfect feel, and change it any time.

Certified Organic Materials, Inside & Out

Made with certified organic cotton, latex, and wool — no polyurethane foam, fiberglass, or flame retardants.

Modular Design for Long-Term Use

Replaceable components extend the mattress’s life and evolve with your comfort. You can keep it forever.

Personalized Comfort. Redefined.

What Does “Customizable Mattress” Mean?

Our customizable natural latex mattresses use interchangeable comfort layers to personalize firmness and support. Each sleeper can choose their preferred feel, with split-firmness options for couples and swappable layers that can be adjusted over time if your sleep preferences evolve.

How Our Modular, Split Firmness Mattress Works

1. Pick Your Firmness

When you’re ready to order, select the feel that’s right for you, with the option to customize each side of the bed.

2. Set It Up at Home

Your mattress arrives in separate components that come together with a simple, step-by-step setup.

3. Try It Risk-Free for 100 Nights

If the comfort isn’t quite right, we’ll send you new layers to try! Simply unzip the cover to swap them out.

4. Keep It for the Long Run

The modular design lets you refresh or adjust your mattress over time without having to replace the whole thing.

What EOS Classic Firmness Level Is Right for You?

Comfort is personal. That’s why we designed the EOS Classic to adapt to you. This customizable mattress is available in five firmness options, from plush cushioning to extra-firm support, to suit side sleepers, back sleepers, stomach sleepers, and combination sleepers alike — and couples, too.

Comfort + Craftsmanship + Customization.

Naturally Cooling Materials

Comfort starts with airflow. Breathable organic cotton allows heat and moisture to escape instead of getting trapped against your body, while perforated latex adds ventilation throughout the comfort layers. Beneath it all, an open coil system encourages continuous air circulation, helping to maintain a more temperature-neutral sleep environment.

Pressure-Point Relief

Support should adapt to you, not the other way around. Responsive organic latex gently contours to the body, cushioning areas like the shoulders and hips where pressure tends to build. Paired with a supportive coil system that reinforces proper alignment, this combination helps to promote a more balanced, comfortable sleep posture

Motion Isolation

A more adaptive sleep surface makes a noticeable difference. Individually encased coils are designed to move independently rather than as a single unit, reducing the transfer of motion across the mattress. That means less disturbance from a partner’s movement, so you can stay asleep even if they shift positions throughout the night.

What’s Inside Your EOS Adjustable Mattress

Organic cotton, organic wool, and plant-based PLA quilt for breathable comfort.

3” organic latex comfort layer for contouring.

8” encased-coil layer for support.

Organic cotton batting for cushioning.

Organic cotton encasement for an elegant finish, with a brass zipper to access inner layers.

Simpler, Better Materials

Before it becomes a mattress, it starts here. Cotton. Latex. Wool. These materials are selected not just for how they feel, but for how they’re sourced and brought to life: organically.

Organic Cotton Fabric & Fill
Organic Wool Batting
Organic Latex
Plant-Based PLA Batting
Glueless Encased Coils

Organic Cotton Fabric & Fill

Naturally soft, breathable, and gentle on the skin, organic cotton promotes airflow and helps keep your sleep surface cool and comfortable.

Organic Wool Batting

Wool wicks moisture to regulate temperature naturally (and it’s naturally flame resistant, which helps to meet safety standards without chemical flame retardants).

Organic Latex

Flexible yet supportive, organic latex contours to your body for exceptional pressure relief and buoyancy. Like memory foam … without all the toxic chemicals.

Plant-Based PLA Batting

Derived from non-GMO sugarcane, this fiber adds lightweight resiliency and helps wick away moisture for a fresher, cleaner sleep environment.

Glueless Encased Coils

Made in-house from recycled American steel, our coils move independently to reduce motion transfer, enhance edge support, and deliver responsive full-body alignment.

What's Not Inside Your Mattress

No flame retardants icon

No Flame Retardants

This CUSTOMIZABLE bed is the best bed I've ever slept on, and you and the person you share the bed with can choose the personal firmness that makes most sense.

Adam, Verified Buyer

It is not too firm, nor too plush. I am so delighted. It is SO comfortable.

Stephanie, Verified Buyer

The bed is amazingly, perfectly, utterly comfortable right out of the box(es). The way it arrives deconstructed was genius, so it can come in the mail and be handled by one person!

Shay, Verified Buyer

We are two months in and couldn't love it anymore. My wife has been on a mattress harder than she prefers for years, and this solution is a game changer for both of us!

Peter, Verified Buyer

We had high standards and Naturepedic exceeded our expectations. We noticed a difference in comfort and quality of rest immediately.

EOS Classic Organic Mattress Care Instructions
To keep your EOS in great condition, use a mattress protector to guard against spills and wear. You can rotate it head to foot every 3-6 months to promote even use, or rotate the internal layers as desired (just don’t change the order of the layers). Make sure your EOS is placed on a supportive foundation or base, and if your foundation has slats, they should be spaced no more than 3 inches apart. As needed, spot clean with mild detergent and cold water, and avoid soaking or harsh chemicals. You can let the mattress breathe occasionally by pulling back bedding to release moisture, and avoid bending, folding, or prolonged exposure to direct sunlight. A light, natural scent from materials like wool or latex is normal at first and will fade over time.

100-Night Risk-Free Sleep Trials
Sleeping is believing! That’s why we offer a 100-night, risk-free trial. Sleep on it, and if you’re not completely satisfied, you can return it within 100 nights for a full refund. We want you to find the perfect fit for your dreamiest sleep.

Minimized Chemical Exposure
At Naturepedic, we minimize environmental impact and health risks by strictly avoiding flame retardants, phthalates, vinyl/PVC, formaldehyde, and other materials found in conventional mattresses and bedding. We adhere to strict, third-party standards and testing protocols and, in 2024, we became the first mattress brand to become EWG Verified®. View more of our certifications.

Organic Cotton
Certified organic cotton stands out as a safer choice for the environment, farmers, and consumers alike because it’s cultivated without synthetic pesticides or fertilizers, as prohibited by the Global Organic Textile Standard (GOTS). Organic certification ensures adherence to strict environmental and ethical standards, promoting biodiversity, soil health, and fair labor practices. This results in a healthier, more sustainable fabric that minimizes exposure to toxic chemicals.

Organic Wool
When it comes to wool, organic certification ensures ethical animal welfare practices, natural grazing, and soil health standards, benefiting the environment and the animals. It also ensures that no GOTS-prohibited chemical treatments are used in processing, making it healthier for you, the consumer, as well. Better still, wool is naturally flame-resistant, eliminating the need for flame retardant chemicals or barriers.

Organic Latex
Made from the sap of the rubber tree, certified organic latex offers a more sustainable alternative to polyurethane foam, made without harmful chemicals, pesticides, and additives prohibited by the Global Organic Latex Standard (GOLS). This certification upholds strict environmental and social standards, ensuring material integrity, fair labor practices, and support for our planet's rubber tree forests.

Plant-Based PLA
Plant-based PLA (polylactic acid) is a fiber derived from plant sugars. Ours is sourced from non-GMO sugarcane. As a plant-based alternative to petroleum-derived synthetics, PLA helps reduce reliance on fossil fuels while offering a lightweight, resilient material that performs well in bedding applications. By using responsibly sourced plant inputs rather than conventional plastics, PLA supports a more sustainable material system while maintaining the comfort and durability expected in modern sleep products.

Glueless Encased Coils
Our encased coil system is engineered without the use of glues or adhesives, relying instead on precise mechanical assembly and heat-sealed fabric encasements. Each coil is individually wrapped to provide targeted support and reduced motion transfer, helping the mattress respond more accurately to your body. Made in-house using recycled U.S. steel, these coils reflect a more controlled, responsible approach to manufacturing. By eliminating adhesives in this critical structural layer, we prioritize material integrity, durability, and a cleaner overall design.

Sustainability in Every Stitch
Naturepedic has been honored with the Good Housekeeping Sustainable Innovation Award, the Real Leaders® Eco Innovation Award, the Clean Production Action’s Chemical Footprint Project Front Runner Award, the Environmental Working Group Hero Award, and others. We are a Green America Gold certified business and, as a 1% for the Planet Member, Naturepedic donates 1% (or more!) of our annual mattress sales to environmental organizations driving change.

Responsible Packaging
Naturepedic’s packaging is crafted with Mother Nature in mind, featuring kraft paper roll-packing to reduce the need for plastic. We use environmentally safer soy inks, FSC® certified paper, cardboard with high recycled content, and local printing partners to help reduce our carbon footprint. Learn more about our packaging.

Made in the USA
Naturepedic products are consciously crafted in the USA using a blend of high-quality domestic and global materials. By manufacturing here at home, we support local jobs and ensure strict quality control, while our carefully selected global materials help us create products that meet the highest organic and safety standards — plus, we’ve personally tested them so we know they’re oh-so-comfy!

GOTS-Certified Organic Factory
We don’t just get our products certified — we get our entire factory certified, too! The Global Organic Textile Standard requires annual audits of certified factories. This means that our facility, located in Chagrin, Falls, Ohio, is inspected once a year to ensure it continues to meet the stringent standards for organic production, environmental management, and social responsibility.
