Are you looking for a new mattress but want to avoid unnatural chemicals used in the materials of the mattress? In this review I take a look at the EOS Classic, an organic bed in a box mattress from Naturepedic. If you’re Interested in learning more about a mattress constructed with all organic materials, read on for my full review!

Company

Naturepedic believes that organic materials are key to creating a healthy sleep environment. Along with Naturepedic’s regular mattress offerings, they offer a line of baby and children’s mattresses, as well as other sleep products such as sheets and pillows. All of Naturepedic’s products are made from organic materials, for which the certifications can be found on their website.

Construction

The major focus of the construction is the use of organic materials throughout the mattress. The use of organic cotton in the cover as well as the latex comfort layer work together to create an organic mattress for a comfortable sleep environment.

I should note that the EOS Classic comes in a few different firmness options and during this review I take a look at the construction of the Cushion Firm, which is the second softest version. There is the ability to choose split firmness levels, for either side of the mattress, for queen sized mattresses and above.

Setup of the Naturepedic is a bit more involved than other bed in a box mattresses, if you would like to see my experience setting up of the EOS Classic you can check out my unboxing post here!

Cover – The cover is made of 100% organic cotton and is pretty soft. I found the material to be breathable, helping with the temperature regulation and cooling of the mattress. I should note that the cover of the EOS Classic is quilted with a layer of soft foam, which provides some initial comfort and pressure relief.

Comfort Layer – Just beneath the cover of the Naturepedic EOS Classic is a 3 inch thick layer of organic latex foam. This layer provides pressure relief and comfort to the sleeper. Latex as a material is known for having a quick response to pressure, giving the mattress some bounce.

Latex foam is also known for its cooling qualities and will help to defend against sleeping too hot. The comfort layer is also aerated to allow increased airflow to improve breathability of the mattress for temperature regulation.

Support Layer – Below the comfort layer is the support center of the mattress, which is made up of 8 inch tall pocket coils. Pocketed coils are individually wrapped, which helps to isolate motion as well as provide some contour to the body. A tall coil layer such as this also creates air space in the mattress, which allows for increased airflow for cooling.

Differences in Construction: As I mentioned before, this review takes a look at Cushion Firm version, but the EOS Classic does come in a few different firmness options. Naturepedic offers Plush, Cushion Firm, Firm and Extra Firm firmness levels, and these can be mixed for separate firmness levels on either side of the mattress for queen size and above. There is also the option to create EOS Classic mattresses that do not use latex in Plush, Cushion Firm and Firm levels.

Firmness

When first pressing into the mattress the initial feeling is of the soft quilted cover, which allows you to sink in a bit for pressure relief. Below that I began to interact with the latex comfort layer and spring support. Both the comfort and support layers have a quick response to pressure, which give the EOS Classic some bounce so you won’t feel stuck in the mattress.

Pressing into the EOS Classic

People often feel the firmness of a mattress differently because of different body types and weight distributions. Rather than giving just my opinion on the overall firmness level of the Naturepedic EOS Classic, I enlisted three other people to give their opinion as well. This should give you a better sense of the firmness range you can expect.

Showing the firmness ratings from four testers

The average firmness results from the testers comes in at 7/10, with a range of 6.5 – 7.5 out of 10. These ratings are pretty close to each other, meaning there was general agreement from all testers on the overall feel of the EOS Classic. 6.5/10 is generally thought of as medium firmness, so all the testers found the mattress to be pretty close to the middle in terms of overall firmness.

I personally rated the firmness at a 7.5/10 on the scale. I found that the support coils of the mattress and the responsive latex combined to keep me from sinking too far into the Naturepedic EOS Classic. While I felt comfortable lying on this firmness level, you may want to select a more plush level if you sleep on your side.

Pressure Map

Instead of just describing the feel of the EOS Classic I wanted to give a visual representation of where someone may feel pressure points while lying it. To do this I placed a pressure map on top of the mattress and lied on my back, side, and stomach. On the image below pressure will be represented from blue (low pressure) to red (high pressure).

When I first lied down on my back there was low pressure across my entire body. My weight is evenly distributed and, like the pressure map shows, I didn’t feel any formation of specific pressure points. I found that while I did sink into the quilted cover a little bit, the EOS Classic provided strong support and kept my back in line in this position. Also, the latex comfort layer responded quickly to pressure, so I didn’t feel stuck as I changed positions on the mattress.

Once I rolled onto my side the pressure map shows increased pressure, which is expected due to higher weight concentration of a lower surface area. Side sleepers will want to be careful with pressure at the shoulders and hips, which can often be problem areas on firmer mattresses. I’m about 5’10” and 190 lbs and found this mattress to be a little bit firmer than medium, so if you are a bit heavier or strictly sleep on your side you may want to look into one of the plusher levels of the EOS Classic.

My weight is again evenly distributed once I’m on my stomach and the map shows low pressure across my body again. Strict stomach sleepers often prefer firmer mattresses as they keep their hips from sinking in and putting their backs in a bad position. I found that the EOS Classic had strong support and kept my spine aligned well.

Motion Transfer

If you are sharing your bed with a partner, you will want to know what it will feel like when the other person gets into and out of bed or tosses and turns during the night. This next test is helpful in showing the intensity of motion that is detectable from one side of the EOS Classic to the other.

For this test I dropped a 10 lb steel ball from heights of 4 inches, 8 inches, and 12 inches and measured the disturbance on the other side of the mattress. This should be pretty intuitive: the bigger the lines, the bigger the disturbance.

The 4 inch drop simulates someone changing position on the other side of the mattress and I was a bit surprised by the amount of motion transferred on the EOS Classic. Given the individually wrapped coils and split construction of the support and comfort layers I thought there would be less motion felt across the mattress. The 8 and 12 inch drops also showed large disturbances and I believe these results can be attributed to the bounce of the mattress.

Sinkage Test

Many people will want to know whether they will feel as if they’re sitting on top of or sinking into a mattress. In order to get a better idea of how someone might sink into the EOS Classic, I used four balls of varying sizes and densities (a 6 lb medicine ball, a 10 lb steel ball, a 50 lb medicine ball, and a 100 lb medicine ball) and placed them on the mattress to measure how much they compress the surface.

These different sizes, weights, and densities help to imitate different body parts or different sized people to show how far into a mattress you may sink.

  • 6 lb medicine ball: 1.5 inches of sinkage.
  • 10 lb steel ball: 2 inches of sinkage.
  • 50 lb medicine ball: 4.5 inches of sinkage.
  • 100 lb medicine ball: 6 inches of sinkage.

Edge Support

If you’re going to share your bed with a partner and and need to use the entire surface area of the mattress then edge support is something you are going to want to take a look at. Bed in a box mattresses can struggle to live up to the edge support of traditional innerspring mattresses, so I wanted to have a look at how I would feel near the side of the EOS Classic.

Naturepedic Mattress Edge Support Laying

Lying on my back near the side of the EOS Classic I felt well supported, with little difference in the support from the center of the mattress to the side. You can see in the image above that I didn’t sink into the mattress much in this position and could get close to the side without affecting the shape of the edge.

I was also able to roll around and change positions without feeling like I would collapse the side of the mattress. When hanging off the side of the mattress I did compress through the quilted cover and latex comfort layer a bit, but still felt secure on the side of the bed.

While sitting on the side of the bed, think putting your shoes on in the morning or getting into bed at night, I found the support system did a good job of helping the EOS Classic keep its shape. This may not be the most important position when deciding on a mattress, but does a good job showing what an increased weight concentration can do to the edge. Overall I would say the EOS Classic performed very well on the edge support portion of the review.

Now that we’ve taken a deep dive into the Naturepedic EOS Classic it’s time to discuss who I think it would be a good fit for.

  • Organic Mattress: Naturepedic specializes in making sleep products out of all organic materials. Everything in the mattress, including the cover and latex foam comfort layer, is made of organic materials.
  • Strong Support and Bounce: Latex is known for having a quick response to pressure, so you won’t feel stuck in the mattress. The coil support system below also provides some springiness to the mattress and I felt did a good job keeping my back in line.
  • Sleep Cool: The comfort layer is made of latex, which does a good job of dissipating body heat, and is also aerated to improve breathability of the mattress. Along with that, the tall coil support layer creates space in the mattress for increased airflow and cooling.
  • Split Firmness Levels: As I mentioned the EOS Classic allows you to choose different firmnesses for queen size mattresses and above. If you and your partner have different sleep preferences or positions this mattress could be a good option for you.
