Wool wicks away moisture, provides natural fire protection, and offers temperature regulation, keeping you warm in the winter and cool in the summer. It has a natural crimp that gives it bounce, body, and soft support characteristics. Plus, Naturepedic's organic certifications ensure healthy, well-treated sheep and the elimination of harmful chemicals during processing.

PLA is a high- performance synthetic fiber made from non-GMO sugarcane that adds resiliency and improved moisture wicking for a more comfortable night’s sleep. PLA is plant-based and is used in a variety of industries, including food packaging and medical supplies and does not contain or off-gas harmful chemicals.

organic latex

Latex is known for its comfortable pressure-point relieving qualities. Best of all, it's made from the sap of a rubber tree! Unlike synthetic and even all-natural blends, all of our latex is GOTS approved for use in certified organic mattresses and is sourced from reputable certified suppliers. This ensures purity, fair labor practices and support for our planet's rubber tree forests.


How can one EOS mattress offer different firmness levels?

The inner layers are accessible via zipper and can be stacked in different configurations to achieve just the right feel. Think of each configuration as a unique "recipe" which is customized just for you. When you choose a standard firmness level (i.e. "firm," "medium," etc.), you are picking a preset recipe of layers that results in that comfort level. The recipe can be adjusted at a later date if the feel is not exactly what you want. We recommend that you start with one of our standard recipes (extra-firm, firm, cushion-firm, medium or plush) and then adjust as needed after you have tried at home. You can swap layers with us for free for 100 nights.

What are the standard configurations for each comfort level?

The coils come in three firmness levels: extra-firm, firm and soft. The latex comes in three firmness levels: firm, medium and soft. The following are our standard recipes:

"Extra-Firm" = firm latex over extra-firm coils
"Firm" = medium latex over firm coils
"Cushion-Firm" = soft latex over firm coils
"Medium" = medium latex over soft coils
"Plush" = soft latex over soft coils

Read this blog post to learn more about choosing the right firmness for you.

What is the ideal firmness for side sleepers/back sleepers/stomach sleepers?

There is no perfect rule, but the goal is to find the firmness that keeps your spine aligned. Generally, side sleepers will like a softer mattress since their shoulders and hips push further down into the mattress. Stomach and back sleepers can usually be comfortable on any firmness type, and it comes down to personal preference. Ultimately, however, it is extremely subjective. The benefit to EOS is that you don't need to stress about it. Start with your best guess. Then change it for free without the need to return and buy a whole new mattress. Our specialists will work with you to swap out layers at home until your mattress is just right.

How do I order an EOS Mattress?

Step 1: Select "Mattress Size" (i.e. Queen, King, etc.).
Step 2: Select "Left Side Firmness" and "Right Side Firmness".
Step 3: Optionally add a foundation.
Step 4: Click "Add to Cart." Your custom mattress order will be generated and added to your cart!

How does the layer swap program work?

For the first 100 nights, you can swap layers for free to achieve your perfect feel. For more details see our layer swap program. But it doesn't end there. You can purchase new layers for your EOS mattress at any time, even five or ten years later. While most mattresses only last 7-10 years, the EOS mattress can be refreshed by replacing the top layers, which will make your bed feel like new again without the need to buy a new mattress.

Can I buy individual layers separately?

Yes. You can order them here.

How does the EOS mattress ship?

Twin, TwinXL and Full sizes ship in three boxes
Queen, King and California King sizes ship in four boxes

All boxes ship via Fedex or UPS ground. Each box weighs between 30-55 lbs. So the components can be carried to their final destination by one person.

Can I order the EOS without latex?

Yes! Any latex layer can be swapped out for a coil equivalent. The latex-free version can be ordered here.

Can I order the EOS without coils?

Yes! Our EOS Trilux is an all-latex mattress. It is made with three layers of latex instead of the hybrid mattress design of the EOS Classic.

Do I need a foundation/box spring with the EOS mattress?

No. The purpose of a foundation is to support the mattress above it and to bring the surface of the mattress to a height that is comfortable for getting in and out of bed. If you have a bed that comes with a supportive platform at the correct height, there is no need for a foundation. If your platform is made of slats, please ensure that the spacing between slats is no more than 3" apart. Slats that are spaced too far apart can create grooves in the bottom of the mattress over time.

How long does assembly take?

About 10-15 minutes. We recommend having two people for assembly, but this is not strictly necessary. For assembly instructions watch our assembly video above.

How is EOS Pillowtop different from EOS Classic?

EOS Pillowtop offers an extra layer of latex compared to the EOS Classic version. This allows for an even more nuanced selection of firmness and comfort levels. For example, if you like a really soft mattress, you will want to opt for the ultra-plush version, which is only offered in the EOS Pillowtop line.

What is the maximum weight limit for the EOS Organic Mattress?

Twin/TwinXL - 325 lbs, Full - 450 lbs, Queen - 550 lbs, King / Cal King - 700 lbs.
