Best For
- Back or stomach sleepers
- Fast response time
- Great pressure relief
- A medium firmness feel
Considerations
- Has high levels of motion transfer
- Less than ideal edge support when sitting
Our Verdict
The Helix Dusk is a hybrid mattress that uses an 8″ layer of pocketed coils and two layers of foam to provide support and comfort, primarily designed for back and stomach sleepers. The Dusk provides good pressure relief with a medium-firm feel.
It has good sinkage and contour with a fast response time, but also comes with higher levels of motion transfer, which is less than ideal for those who sleep with sensitive partners.

How is Helix Dusk Different?
The Helix Dusk has overall performance that is below the average level, but also a price tag that is below average as well—for a savings of 19% compared to the average hybrid mattress.
Advantages
Beyond price alone, other advantages of the Helix Dusk include better cooling performance,
Neutral Factors
This mattress has 5% deeper sinkage than average as well as 6% more bounce than average. Both of these factors are still within an acceptable range and would be more considered to be neutral (preferential) factors than anything else.
Disadvantages
The biggest disadvantage of the Helix Dusk is higher levels of motion transfer (35% more than average) as well as poorer edge support, with 27% deeper sinkage when seated directly on the edge.

Cooling Test
On the Helix Dusk, our objective data showed a pretty good score regarding cooling performance.
This mattress had a maximum surface temperature of 90.7 degrees, which is among the lower side of the mattresses we’ve tested. The average maximum temperature across all the mattresses we’ve tested to date is 91.7 degrees.
Baseline Temp.
85.1° F
Max. Temp.
90.7° F
Ending Temp.
85.0° F
Max. Temp.
Ending Temp.
- Baseline Temperature – the temperature of the mattress before anyone lies on it
- Maximum Temperature (0 minute) – the temperature of the mattress after lying on it for 15 minutes
- Ending Temperature (5 minute) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes
Compared to other Helix mattresses it’s also among one of the coolest surface temperatures.
Heat Dissipation Over Time
Heat dissipation was pretty good, though it did take 3 minutes before the mattress returned to near baseline temperatures.
Speaking subjectively, I found the mattress to offer good cooling overall. During our tests, I did not sense any excessive build-up of heat.
Like all Helix mattresses, the hybrid really carries the heavy load. It’s able to create lots of airflow and when combined with the top layer of latex-like foam, it works well together to keep sleepers cool.
Sinkage Test
The Helix Dusk had 2.28″ of sinkage in our tests, just slightly deeper than the 2.17″ average.
Sinkage Depth
2.24″
Sinkage Feel
Moderate
There’s plenty of sinkage available to create a nice level of edge support, but it’s certainly not excessive, nor will it lead to a “stuck” feel for most sleepers.
As you can see in the photo, when tested with a weighted medicine ball, there was 2.28″ of sinkage into the surface of the mattress. According to Helix, the mattress is designed for stomach and back sleepers. However, based on the sinkage depth, I think it’s a perfectly acceptable choice for many side sleepers also.
The Dusk’s 2.28″ of sinkage is just slightly higher than the average sinkage across all mattresses we’ve tested to date, which is 2.20″.
Motion Transfer Test
The level of motion transfer is documented in the video below.
Motion transfer on the Dusk was very high. In fact, it’s one of the highest motion transfer levels we’ve seen in any mattress tested to date.
These higher levels are likely due to the fact that the mattress has a little more dense support, a design choice making it better for stomach and back sleepers.
Max. Acceleration
8.27 m/s²
Min. Acceleration
-5.86 m/s²
Accel. Range
14.13 m/s²
This added support just creates a little more pushback on motion generated, hence transferring more motion across the surface of the mattress.
While this may be bad for couples concerned about excessive motion transfer, it certainly has its benefits too for sleepers who primarily sleep on their back or stomach and want that added support.
You can see these results played out in the motion transfer graph above as well. There are high levels of motion transfer initially and that motion tends to travel a good amount of time (and distance) before fully being absorbed into the mattress materials.
There is a high level of energy detected for 0.7 seconds, and then it begins to more rapidly dissipate.
Response Test
The Dusk may have some drawbacks in terms of motion transfer, but they scored a very fast response time.
Mostly Recovered
0.3 sec.
Complete Recovery
0.6 sec.
The level of responsiveness is documented in the video below.
Upon dropping the ball in our test, the mattress was mostly recovered around 0.3 seconds. The latex-like top layer and coils work together to great effect to achieve this speedy response.
The fast response time means you will never feel “stuck” in the materials and ease of movement is high.
Bounce Test
There is a high level of bounce at 10.24” of total bounce range. This is similar to what we’ve seen from most hybrids in general, but also from Helix larger family of mattresses.
Max. Depth
6.12″
Max. Rebound
4.12″
Total Bounce
10.24″
The level of bounce is documented in the video below.
The hybrid design is able to deliver more bounce, which offers a more traditional feel, while also being preferable for amorous activities.
Max. Sinkage Depth
Max. Bounce Height
The bounce range of 10.24″ is a good bit above the average 9.65″ bounce range that we’ve seen across all other mattresses we’ve tested to date.
Edge Support Test
Edge support was a bit of a mixed bag. While sitting, we experienced compression at 5.25”.
That’s definitely among the deepest compression we’ve tested (we’ve only seen a handful of mattresses exceed that number).
Max. Sinkage
5.25″
Lying Support
Excellent
The level of edge support while seated is documented in the images below.
Sitting, 140 lbs.
Sitting, 200 lbs.
While edge support for sitting is near the maximum for what we like to see, lying on the mattress was a different story.
The level of edge support while lying is documented in the images below.
Lying on Edge, 140 lbs.
Lying on Edge, 200 lbs.
Lying edge support is simply fantastic. Honestly, I was a bit surprised at how deep the compression was while sitting given how well I felt supported while lying on the mattress.
In any case, overall I feel that the Helix Dusk offers excellent edge support. While sitting directly on the edge or if you use the edge of your mattress for the dance without pants, you may find it doesn’t quite have what you’d prefer, however, for sleeping it’s more than sufficient.
Sex Test
The best mattresses for sex have high bounce, good edge support, quiet materials, and good pressure relief and cooling.
These 5 factors make up the NapLab sex performance score.
Sex Factor | Factor Weight | Score | Rating |
---|---|---|---|
Bounce | 60% | 10 | High |
Edge Support | 20% | 8.9 | Good |
Noise | 10% | 9 | Moderate |
Pressure Relief | 5% | 9.5 | Excellent |
Cooling | 5% | 9.5 | Excellent |
For the Helix Dusk, these individual factors generated a sex score of 9.6.
Overall, this is a very good score for any mattress. Hybrids tend to score exceptionally well in this category because of their sufficient bounce, edge support, and cooling.
The Helix Dusk was no exception. Those three areas were big factors in the successful score. The quality design also contributed to great pressure relief.
Noise takes a bit of a hit because of the coils used in the core of this mattress.
Lastly, let’s talk about edge support. While it’s true, hybrids generally do have good edge support because of the coils, the Dusk struggled a bit with sitting on the edge.
But if you’re more concerned with support when lying on the edge, the Dusk was a real winner and I did not notice any issues whatsoever.
Pressure Relief Test
The Helix Dusk has great pressure relief. No major complaints. It provides sufficient support and where sinkage is allowed, I did not feel like it caused painful pressure points or tension.
Comfort Layer
3.0″
Support Layer
9.0″
There is a 3” layer of comfort foam and 8” of pocketed coils that provide both transitional pressure relief and support. I felt both supported and comfortable in all sleeping positions.
Off-Gassing Test
Off-gassing of the Helix Dusk mattress was pretty typical for a partial foam mattress. Because of the coils, it was less than most 100% foam mattresses, but more than you’d see with a coil-based mattress.
Initial Smell Strength
Moderate
Off-Gassing Period
2 days
Out of the box, there was a moderate amount of smell from the originally compressed mattress. In a well-ventilated space (and without bedding), it took about 2 days for the mattress to fully off-gas.
Again, this is pretty typical for a hybrid mattress and once the process was complete, I did not notice any overwhelming smells.
Company
The company score takes a look at factors that may influence your experience with the mattress.
Factors include length of the trial period, warranty, shipping / return costs, and country of origin.
Company Factor | Factor Weight | Score | Data |
---|---|---|---|
Trial Period | 25% | 9 | 100 nights |
Warranty | 25% | 10 | 10 years |
Shipping | 25% | 10 | $0 |
Returns | 25% | 10 | $0 |
Country of Origin | 0% | USA |
Helix Sleep, as a company was first launched in 2015 and is pretty well known for fair and favorable consumer policies.
They offer a 100-night trial period, with a 30-night break-in period (not unusual terms).
This “Break-In Period” is a 30-day window to allow for your body to get used to the mattress. In this window, you cannot be issued a refund or return the mattress. The 30-day window is the estimated time it takes for your body to get used to any new mattress.
If after the 30 nights you still don’t think Helix is right for you, you have some options.
- Option 1: Return the mattress and get a refund.
- Option 2: Return the mattress and purchase a different Helix mattress.
- Option 3: Request a free mattress topper from Helix. This is a good option if you want the mattress just a touch firmer or softer. If you receive the topper and the feel still isn’t right, you can still return the mattress (and keep the topper).
How firm is Helix Dusk?
The Helix Dusk has a medium firmness. I would consider it to be around a 6 out of 10 on the firmness scale.
Compared to some other Helix models, this puts it about at the same firmness as the Helix Midnight.
For something significantly softer, check out the Helix Moonlight or Sunset. For something significantly firmer, check out the Helix Twilight or Dawn.
You can see a full breakdown of each mattress type, its firmness, and who it may be best for below.
Mattress Type | Firmness | Best For |
---|---|---|
Helix Sunset | Soft | Side sleeper |
Helix Moonlight | Soft | Back or stomach sleeper |
Helix Midnight | Medium | Side sleeper |
Helix Dusk | Medium | Back or stomach sleeper |
Helix Twilight | Firm | Side sleeper |
Helix Dawn | Firm | Back or stomach sleeper |
Support & Sleeping Positions
Depending on your body weight and personal sleep position preferences, you may find that certain firmnesses are better suited for you than others.
We try to take the guesswork out by providing the table below. Use this chart as a guide to help decide if the Dusk is a good fit for you.
Helix Dusk
Sleeper Weight | Stomach Sleepers | Side Sleepers | Back Sleepers |
---|---|---|---|
Under 150 lbs. | Yes | Yes | Yes |
150-250 lbs. | Yes | Yes | Yes |
250-300 lbs. | Yes | Yes | Yes |
Over 300 pounds? For heavier sleepers, Helix offers the Helix Plus which is designed to support plus-sized or Big & Tall sleepers. This mattress is 13″ thick compared to the 12″ thickness of the standard Helix mattresses.
Design
The Helix Dusk is a hybrid mattress that uses layers of foam and pocketed coils to provide support and comfort.
Type
Hybrid
Thickness
12″
Firmness
6
It is specifically designed to offer better support for stomach and back sleepers, while still hitting a 6 out of 10 firmness.
In my view, it does exactly that. The support is solid, even on the edges, but it still provides a strong level of comfort.
All that said, for many side sleepers I still feel that the Dusk is a perfectly fine mattress.
Materials
There are four main layers in the Helix Dusk mattress. The breakdown is as follows:
- 1.5″ poly foam
- 1.5″ memory foam
- 8.0″ pocketed coils
- 1.0″ support foam
The Cover
The cover of the mattress is a thin, breathable material, with good stretch and airflow. It sits taught against the surface of the mattress and easily adapts to body contours as you move.
The Comfort Layer
The comfort layer is made up of two thinner layers of foam. On the top is a 1.5″ layer of poly foam for responsiveness and cooling. Directly below the memory foam is a secondary layer of 1.5″ memory foam.
This layer of memory foam is designed for contouring, hug, sinkage, and pressure relief.
Memory foam tends to retain heat a bit more so by placing this foam between the poly foam and the pocketed coils, much of those drawbacks are reduced.
The Support Layer
The support layer is the thickest part of the mattress, containing hundreds of pocketed coils and support foam.
As a sleeper moves or rolls on the mattress pressure is distributed across the mattress and divided among the coils for even weight distribution.
This would usually also mean that there are lower levels of motion transfer, but we didn’t really notice that with the Dusk. Since the upper foam layers are a bit springier, they actually allow for higher levels of motion transfer.
Below the coils, there is also a 1.0″ layer of high-density support foam.
Product Evolution
When Helix Sleep first launched mattresses back in 2015 they were poised on the concept of a completely custom mattress. To purchase a mattress, you would fill out answers to their Helix Sleep Quiz and based on those answers, an ideal mattress would be recommended to you.
They even offered the option to customize each side of the mattress to meet the needs of different sleepers.
Today, Helix offers 13 different mattresses with varying levels of firmness, feel, and materials.
All current Helix mattresses are hybrid blends of foam and coils. You can still take a Sleep Quiz (like in the early days), but the results of the quiz will point you to one of their pre-existing mattress models.

The WinkBed is another hybrid mattress that uses foam and coils for comfort and support. Unlike the Helix, the WinkBed has a pillow-top cover, which provides a more traditional feel.
Coil-on-Coil
Saatva
Luxury Coil-on-Coil
The Saatva mattress uses two layers of coils, instead of just one, for more bounce while also offering less motion transfer. It has a plush, pillow-top cover.
Organic Hybrid
Birch by Helix
Perforated Latex + Coils
For a slightly firmer feel and more organic materials, check out the Birch by Helix. Birch comes in around a 7 out of 10 on the firmness scale. Instead of using poly and memory foam, Birch uses a 2″ layer of perforated organic latex for cooling and comfort atop the 8″ coil base.

The purchase of any Helix mattress comes with a 100-night trial period and free shipping to your door. If you decide that the mattress isn’t right for you, they offer free returns, but you’ll need to wait through the end of the 30-night break-in period.
Compressed mattresses tend to adjust in feel as they fully expand and begin to relax. This alone can take some time. In addition, your body will take time to adjust. We recommend giving a new mattress a few weeks for your body to truly adjust before deciding if you love or hate a new mattress.
If you want more than the standard 10-year warranty, check out the Luxe versions of each mattress. The Luxe offers a 15-year limited warranty.
No. Right now, the only way to try a Helix mattress is to buy it (unless you happen to have a friend with a Helix!)
If you find that you don’t love the Helix after the 30-night break-in period, you have some options. You can (1) return the mattress. Or (2) you can request a firm or soft mattress topper from Helix at no additional cost. This is a nice option if you like 90% of the mattress, but the feel is not 100% right.
