I have reviewed hundreds of mattresses, sheets, pillows, duvet inserts, comforters, sleep gadgets, and adjustable beds. My reviews are based on my personal experience and the feedback I get from customers.

The EOS Mattress from Naturepedic is a 12-inch organic mattress that can be fully customized. That means you can choose to go with springs and latex or if you have a latex allergy, go the all spring route. Naturepedic will substitute the top latex layer with micro-coils that provide great cushioning and support underneath the thick mattress cover.

The EOS is a bit more expensive than many of the online competitors but it is a quality mattress inside and out. There aren’t that many organic spring mattresses out there that are this customizable. This is the only natural mattress I have reviewed where you can substitute the latex layer for a spring layer to avoid allergy issues.

After you order your mattress it should arrive in about 7-10 days. It comes in multiple boxes as seen below.

You get assembly instruction which shows you how to set up the mattress.

Each box is labeled so you know which one to open first.

Below is a video overview of the mattress after it has been assembled.

The EOS mattress doesn’t have a free trial like most online brands but they do have a 90-day comfort guarantee where if you don’t like the feel of your mattress, they can switch out some of the components. Here are the details of the comfort guarantee from their website.

90 Day Comfort Exchange Policy – Swap any 3″ comfort layer within 90 days of your purchase and only pay for shipping. Just fill out a simple form at and order your new layers.

My Naturepedic EOS Findings

Right from the beginning, this product screams quality. The boxes are clean and well labeled and the contents are packaged neat and secure.

Here’s the mattress cover out of the box. This is a thick cover that not only keeps everything together, it provides a nice padded surface for sleeping. There was also no smell to this. Sometimes an all organic cover can smell like a sheep due to the wool batting but this one didn’t smell at all.

Even the zipper is very high quality. This is important because the mattress is designed to hold all the materials tightly together which means that you sometimes need to pull hard on the zipper. Having a quality zipper makes the job easier and less likely that you will break it.

For my review I had a soft and firm configuration on a queen size mattress. This allowed me to test both ends of the firmness spectrum. I also opted for a latex layer instead of the microcoils so I can’t really speak to how the microcoils will feel.

Below is a video of me dropping a bolwing ball on the soft side of the mattress.

And here is the same bowling ball on the firm side of the mattress.  I found the soft side had a bit more bounce.

Here’s another view for comparison that shows how much the ball sinks on each side. Below is the firm side.

And here is the soft side.

As you can see there is a significant difference between the soft and firm versions. Of course you can go with a medium firm as well.

Despite being a spring and latex/coil mattress, it handles motion transfer very well. That’s because not only the latex and microcoil systems are separate pieces, the base pocket coil system is two separate units as well. As you can see in the picture below.

My Naturepedic EOS Recommendation

Naturepedic is a leading natural mattress manufacturer. They have all kinds of certifications that are a testament to the quality of their product. Their products are made by Amish craftsmen in their factory in Ohio. So, from the beginning, you are getting a quality product that should last a long while.

I found the soft configuration of the EOS to be a great feel for my preferences. It’s great for side sleepers. Stomach and back sleepers will want to go for the medium and firm configurations.
