Meet the Helix mattress! Helix Sleep is a new mattress start-up company and one of the first online companies to offer a 100% customizable sleep experience. Helix Sleep is moving away from the one-size fits all option and instead allows sleepers to fill out a short list of questions designed to identify their ideal mattress.

But does an individually personalized mattress design actually make a difference? Sleepopolis decided to put them to the test! Continue below for my full review of the Helix mattress.

Layers

The Helix mattress is a 10″ all foam mattress built from 5 layers of latex, polyfoam, and microcoils. Each Helix mattress is customized based on the specific needs of the sleeper(s). The order of the layers, along with their firmness and density, vary depending on the personalization needs of the mattress. The following diagram and information is based on the custom mattress design that I tested for this review.

  • Top layer (comfort + cooling) – this is a 2″ layer of Dunlop latex. Dunlop latex is known for its durability, bounce, cooling, and responsiveness. This is a synthetic Dunlop latex. The Dunlop comes in varying firmness levels (ILD 15-32) depending on the needs of the sleeper. ILD (Indentation Load Deflection) is a measure of firmness. For more info on ILD check out the mattress glossary.
  • 2nd layer (pressure relief) – this is a 1.5″ layer of microcoils. Microcoils are miniature coils that provide softness, pressure relief, and a nice bounce. These help give the Helix mattress a little bit closer to the innerspring feel. The ILD of the microcoil layer is always 18.
  • 3rd layer (support) – this is 2″ polyfoam transitional support layer. It helps the comfort layers and base layer work together, while also providing support and deep compression support. It has an ILD of 20-26.
  • Bottom layer (foundational) – this is a 4.5″ layer of high density support foam (typically split into two separate foam layers). It simply acts as a strong foundational support base for the above comfort layers. The ILD densities range from 26-33.
Helix mattress layers (top to bottom): 2" of latex foam, 1.5" microcoils, 2" polyfoam, 4.5" support foam

The Helix mattress cover is built from 100% polyester. The top white piece of fabric is soft to the touch and the blue side panels have a sturdier feel that will help to protect the mattress. The cover has a modern aesthetic, with a subtle checkerboard pattern on the top piece of fabric. Additionally, it’s quite thin and has no padding. This allows air to flow more easily, improving cooling, while also allowing sleepers to engage directly with the foams and microcoils.

Firmness, Comfort, & Support

Normally in this section I would discuss the Helix mattress’ firmness, comfort, support, cooling, bounce, and other feel factors. However, since the Helix mattress is 100% customized that’s going to make this section a little bit harder.

Every Helix mattress is made to order based on the sleeper’s specific requirements, needs, and desires. Before you place your order for a Helix mattress you need to complete their short mattress quiz. This quiz has questions on your desired firmness, support, cooling, positions you sleep in, medical conditions, and other questions that help Helix align your needs to the ideal mattress setup.

Since my weight, height, body type, and sleeping preferences are likely very different than yours, it just didn’t make sense to really discuss the feel of my specific mattress. So in place let’s walk through the mattress quiz selection process and I’ll show you how these questions determine the feel of each Helix.

The Helix mattress quiz covers: mattress size, number of sleepers, gender, height, weight, body type, sleeping positions, cooling needs, firmness preference, medical issues, and any sleep related pain.

After you’ve completed the quiz you’ll see your results. Your results are based on 4 major pillars: point elasticity, support, feel, and temperature regulation.

  • Point Elasticity – How does compressing a single point on the mattress impact other surrounding areas on the mattress? This is important as it dictates how the mattress contours and conforms to the shape of your body.
  • Support – How much support do you need for your spine to remain in alignment? Your sleeping position, height, and weight determine the level of support you’ll need for optimal alignment, without creating pressure points.
  • Feel – aka firmness, how soft or hard is the mattress? This is determined by your preferred firmness level (your weight also plays into this, as it will change the density of the materials required to deliver that firmness level).
  • Temperature Regulation – how cool does the mattress sleep? Some people sleep extremely hot and will need a different construction to accommodate those needs, others just need something that doesn’t warm up.

Below are the results for the mattress that I tested. In general, my wife and I are fairly average in most of these areas. We don’t like an excessive hug in a mattress, we prefer a medium (5-6 out of 10) firmness, and we don’t sleep tremendously warm (though we do need a fair amount of cooling). Point elasticity, feel, and temperature regulation were in the median ranges. Support was a bit on the lighter side, most likely due to our respective weights. I have a lower BMI of 18.5 and my wife is about average height and weight. As a result, we need support that has a little more give in it, otherwise it can create pressure points and become uncomfortable.

At the end of the day, I would say my wife and I got about what we expected. Our customized mattress was a 5.5-6 out of 10 on the firmness scale, slept fairly cool, had average support, above average bounce, and a balanced contour / hug. We selected the “medium” firmness level for our mattress. In retrospect I wish we had gone with medium firm. As a stomach sleeper I found it to be a little more sinkage than I typically prefer and need to maintain good spinal alignment. However, my wife found the sinkage to be on point as her preferred position is sleeping on her side.

Blended & Split Mattress Types

Helix offers both a “blended” and a “split” mattress. A blended mattress simply means that Helix takes into consideration the needs of both sleepers (assuming you sleep with a partner) and creates a mattress you you’ll both love. It isn’t an average of your needs, but instead looks and at the higher priority needs of each sleeper to make construction specifications.

When I ordered my Helix I assumed the split design was the same as other split mattresses, in that you’d get two separate mattresses…not so. If you select split design two separate mattresses will be designed and customized to the specific needs of each partner. These two mattress halves will be affixed and cured in the final stages of construction, forming one seamless mattress with a completely different feel on each side. Note that this extra curing process does add 2-3 days onto the manufacturing time for your mattress. Additionally, it’s only available on Queen, King, and California King sizes.

Sinkage Tests

Every mattress reviewed on Sleepopolis goes through a short series of sinkage tests. I created these tests to help give my readers an idea of the sinkage, hug, and feel they can expect from each mattress. A special note on the Helix sinkage tests. Since Helix is a customized mattress the sinkage tests will vary depending on the customization specifications of each mattress. I would estimate that my customizations would be about average (my Helix is fairly moderate in terms of firmness and support). If you select a softer mattress the sinkage will be more dramatic and if you select a harder mattress the sinkage will be less significant. Bear in mind, I am 140 pounds.

  • Lying in the middle – In a normal lying position on my back, with my weight evenly distributed, I saw 1-1.5″ of sinkage.
  • Sitting on the edge (conservative) – In a conservative sitting position, where I was sitting a bit further back on the mattress, but still had my feet on the floor, I saw 2.5-3″ of sinkage.
  • Sitting on the edge (aggressive) – In a more aggressive sitting position, where I was sitting directly on the edge of the mattress I saw 5″ of sinkage.
  • Standing in the middle – Standing in the middle of the mattress with all of my weight focused on a single point I saw 4.5-5″ of sinkage.

Should you buy the Helix mattress?

The Helix mattress is a well built mattress that offers some of the best customization you can find in any mattress on- or offline, but especially at this price point. They use quality Dunlop latex, microcoils, and polyfoam to deliver good support and great comfort. Lastly, the option to have a split mattress is another key differentiator. The technology isn’t unique, but you won’t find the split mattress feature many other places at this price point.

I would recommend the Helix mattress to sleepers who:

  • Want a customized mattress – the biggest and most important selling point, customization. At $900 for a Queen the Helix is incredibly affordable for the level of customization offered. I’ve seen other customizable foam mattresses and they typically range from $4,000-$10,000.
  • You aren’t 100% sure what you need – if you just don’t know what type of mattress you really need the Helix mattress customization quiz can easily walk you through the process. The questions are simple and intuitive.  You don’t have to try to think your way through marketing speak to understand if it’s the right mattress for you. The quiz walks you through your needs and preferences resulting in a mattress that’s design for you.
  • You sleep with a partner and you have very different needs – Helix’s split mattress allows you to get two completely different customized mattress halves in the Queen, King, or California King size. The split mattresses are affixed together with glue and other bonding agents. The end result is two customized mattresses that look cohesive for a seamless aesthetic.
  • You want foam + cooling – Helix Sleep makes a point to deliver your ideal level of cooling. Their personalized design and material selection help to prevent heat retention and improve air flow in every customized mattress.
