Helix Sleep Mattress Review

If you like the idea of a bespoke mattress, this is the closest you’re going to get to that experience without hiring a craftsman to make you one. WIth Helix, the sheer number of options will feel good to you.

Nerd Score: 4.7/5


Helix doesn’t just say they can offer you what feels like a customized mattress.

With nine options in the Helix Sleep line, they back it up.

Mattresses for each sleep position. Mattresses that cover the spectrum of firmness from plush to medium to firm. Mattresses that you can make cooler with a different fabric cover. Mattresses you can make softer with a topper. Mattresses that can be built with two different firmness levels for your honey and you. Mattresses for larger figures. Hybrid mattresses to match a range of tastes and physical needs.

They even built an app on their website that will pick the right mattress for you. Take the quiz. Press a button. Get a recommendation.

The origin story of Helix sounds familiar. Friends bonding over their mutual frustration with finding a good mattress and chasing a decent night’s rest. Friends understanding that the mattress marketplace had changed. Friends designing one mattress and then eight others to reach the most people, regardless of preference or sleep characteristics, they could.

You have to appreciate the effort that went into developing such a comprehensive line of mattresses. If you’re picky and particular, Helix seems confident it has a mattress to fulfill your needs.


Here are some features of the Helix mattress:

  • Nine different options; there’s something in this line for everyone.
  • Different foam types allow Helix to offer so many different types of mattresses.
  • Eco-friendly foam layers are CertiPUR-US®.
  • Color-match system can determine which mattress is best for you.
  • Two dual options for couples—plush on one side, firm on the other.
  • Can upgrade outer cover of the mattress to Ultra-Cool knit cover if need more cooling.
  • Made in the USA.
  • Delivery in the U.S. & Canada.
  • 100-night trial period.
  • 10-year limited warranty.



All Helix mattresses are hybrids made with foam and inner coils. You need more detail. Strap in. Here we go:

Made with Helix Memory Plus Foam (side sleepers, good spine alignment)

  • Helix Sunset
  • Helix Midnight
  • Helix Twilight

Made with Helix Dynamic Foam (extra support for back & stomach sleepers)

  • Helix Moonlight
  • Helix Dusk
  • Helix Dawn

Helix Specialty Mattresses

  • Helix Nightfall—For sleepers with larger figures
  • Helix Dual-Balanced—Made with memory plus foam for balanced support
  • Helix Dual-Extra—Made with Helix Dynamic Foam to provide extra support      


Helix uses foams with natural cooling properties. Because coils always encourage airflow and there are coils in all of their mattresses, Helix mattresses do a solid job keeping you from overheating.

Also, Helix has a special cover that you can buy if you need more cooling. It’s called an Ultra-Cool cover and it’s made out of a knit fabric.


  • Helix Sunset – plush
  • Helix Midnight* – medium
  • Helix Twilight – firm
  • Helix Moonlight – plush
  • Helix Dusk – medium
  • Helix Dawn – firm
  • Helix Nightfall—medium
  • Helix Dual-Balanced—plush on one side, firm on the other
  • Helix Dual-Extra—plush on one side, firm on the other

Edge support

The mix of strong foams and sturdy coils in all Helix mattresses also do the heavy lifting needed to ensure sleepers feel solid around the edges of the bed. You can sleep on the edge comfortably and feel supported without undue pressure on your body curves and the beds will support you if you sit on the edge to get ready in the mornings.

Motion transfer

Helix mattresses, for the most part, keep motion transfer to a minimum. This is important if you sleep with someone. You can feel your partner move around, but the moving likely won’t wake you out of a deep sleep.


Each of the nine new mattress models, except for the three specialty mattresses, feature the same basic construction. The second layer, the comfort layer, is where you get the differentiation of firmness and support to fit so many different preferences.

Depending on the model, this comfort layer will be made with either Helix Memory Plus Foam or Helix Dynamic Foam.

The mattresses made with Memory Plus foam (Helix Sunset, Helix Midnight, Helix Twilight) have proper support and pressure relief for side sleepers without being too stiff.

The models made with Dynamic foam (Helix Moonlight, Helix Dusk, Helix Dawn) provide extra support, a good quality for back and stomach sleepers.

Here is what the mattresses look like inside:

The first layer is the cover made with two layers, which can be zipped over to clean. The stretchable top layer is soft to the touch, while the lower layer promotes airflow and breathability.

For the Sunset, Midnight and Twilight, the second layer, the comfort layer, is 2 inches of Memory Foam. Memory Plus foam is a special foam blend by Helix. It provides pressure relief in areas such as the hips and shoulders.

For the Moonlight, Dusk and Dawn, the second layer, the comfort layer, is 2 inches of Dynamic Foam. Helix designed this foam to give firm support that effectively reacts to and contours to your body.

The third layer, the transition layer, is made of 1 inch of high-grade polyfoam. This provides ergonomic support and cushion.

The fourth layer shapes the body with 6 inches of 660 individually wrapped pocket coils to cradle your body and keep motion transfer to a minimum. Beyond that, the outer coils reinforce the outside of the mattress for better edge support.

The fifth layer is the base layer of 1 inch of DuraDense foam. It’s a dense foam meant to support the entire unit and enhance its durability.

For the specialty mattresses, a couple of layers differ within each to accommodate specific needs.

The Helix Nightfall is a taller, 12-inch mattress with an extra layer of dense foam to accommodate additional weight and higher density materials that are better suited for plus-size and Big & Tall customers.

It’s medium firm and uses the Dynamic Foam so that it is responsive to those curves, limiting pressure so you still get restorative sleep. It also has XL coils to accommodate bigger figures and prevent anyone who carries extra weight from sinking too deep into the mattress.

The Helix Dual Balanced gives couples the best of both worlds—one side plush and one side firm. The mattress is actually split inside using different density support foams depending on firmness needed. This mattress differs in layers two and three. The second layer is the Memory Plus Foam. The third layer is a mix of the Helix Dynamic Foam and additional polyfoam.

The Helix Dual Extra also strives for couple harmony with a plush feel to one side and a firm feel on the other. The Dual Extra uses Helix Dynamic Foam and increases the density of the top and middle layers for additional support.


Here is a breakdown of the Helix mattress:


  • Twin: 39″ x 75″
  • Twin XL: 39” x 80”
  • Full: 54” x 75”
  • Queen: 60” x 80”
  • King: 76” x 80”
  • Cal King: 72” x 84”


90-100 pounds (queen)


10 inches for all mattresses except the Helix Nightfall, which is 12 inches thick



Helix lets you try their mattresses for 100 nights. That’s fairly standard in the industry.  You do need to sleep in it for 30 days before you can initiate a return.

The idea behind sleeping in it for 30 days is that it takes that long to break it in, that long to get used to what it feels like and that long to find out what positive or negative impact it might have on your quality of sleep.

If firmness is an issue, and you find the mattress too firm or soft after at least 30 days,  Helix will send you a complimentary topper for the rest of the 100-night trial to see if that improves the situation. It doesn’t void the trial. You can send everything back if the adjustment still doesn’t work for you.

If you need to return it, call Helix to arrange the return and a full refund. The company will try to donate the mattress to a local charity.


Helix offers a 10-year limited warranty. It covers indentations greater than 1 inch that doesn’t result from using the wrong type of foundation. You have to have the right foundation for the warranty to apply.

It covers any flaw that would cause the foam to split or crack. The warranty doesn’t cover normal wear and tear. The warranty only covers new mattresses, nothing pre-owned or reconditioned, being used by the original owner.

You pay to return the mattress to Helix. If Helix finds a defect, it will reimburse the shipping costs up to $100. Helix promises, in turn, to repair or replace the mattress and get it back to you within 90 days.

Delivery & Setup

The Helix mattresses come compressed and rolled up in an appropriately sized box, i.e. 16” x 16” x 48” for a queen size. Helix delivers in 3-7 business days after receiving your order. They ship throughout the United States.

Once your Helix arrives, you put it on your foundation. Then you remove it from the plastic cover. Give it 45 minutes to expand to its full size and you’re ready to go.

Customer service

Helix offers nine versions of its hybrid mattress. Trying to wade through all of that information would be difficult had Helix not put together a “find the best mattress for you” app on its website. It’s called the Helix Color-MATCH system.

Be grateful. I put myself through the 30-second exercise, filling in blanks asking for basic information and clicking boxes to indicate my firmness and sleep position preferences and to say whether or not I woke up sore or in pain.  

Enter, send, voila! I had a recommendation.

If you want some personal attention or to see the mattresses in person, there is a showroom in New York City. Or take the convenient route and call or email the company for help.


$$ to low $$$ for all models (See scale below).

$$$$$2,000 – $4,000

Helix sells different types of foundations and bases, including an adjustable base if you’re into that sort of thing.

Helix recommends you put your mattress on a firm, flat surface, including the floor or a bunkie board on top of a box spring. If it must have slats, make sure they’re no more than 5 inches apart.

The Helix mattress company swung for the fences when it opened its online doors to the public in several years ago.

They wanted to make a mattress for everyone. Instead of trying to literally make one mattress, they designed nine hybrid models to appeal to a wide range of needs and desires. You can’t question their commitment to the cause.

They manage most of that because Helix went out and designed two different types of foam layers that sit in that key comfort zone. One is firmer than the others and works better for back and stomach sleepers, The other is slightly more plush and is a good fit for side sleepers.

The bottom line: Helix gives you choices and a quick, easy way to narrow them down. The mattresses do a good job across the board with support, pressure relief, regulating your temperature and durability.

If you like the idea of a bespoke mattress, this is the closest you’re going to get to that experience without hiring a craftsman to make you one. WIth Helix, the sheer number of options will feel good to you.
