How is Helix Twilight Luxe Different?

The Helix Twilight Luxe is a 13.5″ hybrid mattress with an overall performance level that is higher than average and a price tag that is also better than average—30% better than the average hybrid mattress.

Advantages

The Twilight Luxe has better cooling performance than average, 30% less motion transfer, and better edge support. This mattress only has 3.0″ of sinkage when seated at the edge, 25% less sinkage than the average mattress.

Pressure relief is better as well, with a thicker comfort layer and an overall thickness that is also thicker than average (13.5″ on the Twilight Luxe compared to a 12.1″ average thickness across all mattresses).

Neutral Factors

The Twilight Luxe has moderate sinkage and low levels of bounce. Sex performance is also considered a bit of a neutral factor since it’s right at the average level.

Disadvantages

The two biggest disadvantages of the Twilight Luxe are a slower material response time and a higher price tag. The average hybrid mattress is less than $1500 ($1450.80 to be exact), but the Twilight Luxe is $448 more than the average cost.

Granted, it also provides a better overall performance, but if you’re on a tight budget, this could certainly be a factor to consider.

The Helix Twilight Luxe has excellent cooling. During our tests, I did not feel any significant level of heat retention around my body.

The mattress did a nice job at keeping the surface reasonably cool and avoiding any major buildup of heat. The Twilight Luxe uses the same proven hybrid design we see on all Helix Luxe mattresses.

The mattress is equipped with high-performance, high-quality foams in the comfort layer. Those foams breathe well and are positioned in such a way as to mitigate heat.

• 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

In addition, we have a pocketed coil unit that’s helping to bring more air into the mattress. In terms of feel, this mattress creates more of a floating feel, which means less sinkage, less hug, and less material wrapping around the body, all of which help resist heat retention.

Lastly, this mattress is available with an optional cooling cover. We didn’t have the cooling cover on our Twilight Luxe, but I have tested it on other Helix models and it does make a major difference.

If you’re a super hot sleeper, it’s definitely worth the upgrade. In our objective temperature tests, we measured a max surface level temperature of 89.6° F.

This is 0.2° less than the average of 89.8° F, based on all of our tests to date. After getting off the mattress, the temperature declined by 5.9° from minutes 0 to 1, which is 1.3° cooler than the average 0 to 1 minute decline of 4.6°.

Heat Dissipation Over Time

When we consider the combination of objective data, my subjective experiences, and an analysis of the materials, I’m confident in my view that cooling is excellent.

The Helix Twilight Luxe has moderate sinkage. During our tests, we measured a pressure point sinkage depth of 2.03″. This is 0.14″ less sinkage than the average sinkage depth of 2.17″, based on all of our tests to date.

The level of sinkage is documented in the image below.

The mattress creates more of a floating feel when lying on the back or stomach. While lying on my side, the mattress has a more balanced feel. Even so, the sinkage depth is still quite restrained, just 0.03” above the threshold that we would call “minimal” sinkage.

While on my side, I can definitely feel more of the memory foam layer within the core of the mattress. That layer is contouring more of the precise shape of the body.

Even so, the other poly foam layers and coil unit balance out the overall feel, so it doesn’t feel overly dramatic or deep in the contour.

Lastly, the firmer feel further restrains the body contouring hug, especially for back sleepers, stomach sleepers, and lighter-weight bodies.

The Helix Twilight Luxe has a very low level of motion transfer. During our tests, we measured a total acceleration range of 6.11 m/s². This is 30% less motion transfer than the average of 8.69 m/s².

The 4.0 PCF memory foam just below the euro top cover is the most significant material factor helping to reduce motion transfer.

Denser memory foams are able to absorb and disperse energy, which keeps motion lower. That memory foam is also keeping bounce to a below-average level, which further helps mitigate motion transfer.

The level of motion transfer is also documented in the video below.

In our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.14 seconds.

Motion takes a big step down thereafter, and by 0.86 seconds, we’ve returned to near-zero levels of energy.

Given the notably lower-than-average motion intensity, I was a bit surprised at the motion duration. Even so, it’s nothing I’m especially alarmed by.

Overall, I’m pleased with this level of motion and expect it will be more than low enough for most sleepers.

The Helix Twilight Luxe is a mixed bag for material responsiveness, with a fast mostly recovered response time and a moderate fully recovered response time.

In our mostly recovered test, we measured a recovery speed of 0.5 seconds, which is 0.07 seconds slower than the average of 0.43 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 1.2 seconds, which is 0.21 seconds slower than the average of 0.99 seconds.

The level of responsiveness is documented in the video below.

Like other models within the Helix Luxe lineup, the denser memory foam within the core of the mattress is slowing down the total material responsiveness time. Most other materials, foams, and the spring unit all rebound back to shape effectively instantly.

However, that 4.0 PCF memory foam takes a moment or two to recover to its original shape. As a result, the fully recovered responsiveness time is a bit slower than average.

All that said, these responsiveness speeds aren’t bad by any stretch. The firm feel and minimal to moderate sinkage depth help to mitigate any major ease of movement issues that might otherwise have been created by the slower responding memory foam. Overall, I found ease of movement to be a non-issue.

The Helix Twilight Luxe has a low level of bounce. During our tests, we measured a total bounce height of 7.99″. This is 1.22″ less bounce than the average of 9.21″, based on all of our tests to date.

As with motion transfer, the real star of the show here is the super-dense 4.0 PCF memory foam. This memory foam layer absorbs and disperses a ton of energy.

As a result, there is simply less energy that’s capable of being returned as a bounce.

The level of bounce is also documented in the video below.

When you combine that memory foam with a thicker-than-average comfort layer, you have the right material conditions to create a lower-than-average total bounce.

Ideally, I want to see bounce closer to 10”. Suffice it to say, we’re well south of that mark. The lower bounce does negatively impact sex performance.

However, ease of movement is sufficient, and the lower bounce also makes motion transfer lower. So there are pros and cons to consider with the lower-than-average bounce.

The Helix Twilight Luxe has outstanding sitting edge support and outstanding lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 3.00″. This is 1.01″ less sitting sinkage than the average of 4.01″, based on all of our tests to date.

The level of edge support while seated is documented in the images below.

While lying directly on the edge of the mattress, I felt that the support was outstanding in all sleeping positions. The Twilight Luxe uses reinforced coils that run along the entire perimeter of the mattress.

The level of edge support while lying is documented in the images below.

In addition, we have a firm feel, minimal to moderate sinkage, and high-performance materials from top to bottom. This combination of design and material choices creates all the right conditions to deliver outstanding edge support for both sitting and lying.

The Helix Twilight Luxe has good sex performance. On the positive side, noise is minimal, and both pressure relief and cooling are excellent. In addition, edge support earned an outstanding score due to just 3.00” of sitting edge sinkage.

That more robust edge extends the total surface area that’s functionally usable for amorous activities. Lastly, let’s talk about bounce. Bounce is, unfortunately, a major weak spot on the mattress.

We have just 7.99” of total bounce height. It’s well below average and makes the amorous activities more strenuous, difficult, and tiring, at least compared to mattresses with more bounce.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	7.5	Moderate
Edge Support	20%	10	Outstanding
Noise	5%	10	Minimal
Pressure Relief	5%	9.0	Excellent
Cooling	5%	9.0	Excellent

At just under 8″ of bounce, it’s not bad by any stretch, but when it comes to sex, more bounce is almost always better. Nevertheless, despite the lower bounce, the total sex performance is still good, even if it’s not great.

The Helix Twilight Luxe has an excellent level of pressure relief. During our tests, I felt no significant pressure points on my body.

The mattress is equipped with 4.75″ of comfort material, which is 0.55″ more comfort material than the average comfort layer thickness of 4.20″, based on all of our tests to date.

The Twilight Luxe uses 1.5 to 1.8 PCF foams in the euro top cover and a 4.0 PCF memory foam in the core. The memory foam in the core is doing much of the heavy lifting when it comes to pressure relief.

You can really feel that specific layer creating the hug and contour around the body. The memory foam works together with the cover foams and 2.0″ poly foam (1.5 PCF) just above the pocketed coil unit to create ample comfort.

In our pressure mapping tests, we measured a max PSI of 0.81 on my side. The pressure on the side was notably higher than on my back or stomach, which makes sense given that this mattress is designed more for back and stomach sleepers due to the firm feel.

Even so, a 0.81 PSI isn’t high by any stretch (a 2.0 PSI is the high benchmark we want to avoid).

Pressure Map – Side Sleepers

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.14	0.81

Pressure Map – Back Sleepers

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.90	0.54

Pressure Map – Stomach Sleepers

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.09	0.43

When I consider the material thickness, material quality, and my subjective experience on the mattress, I’m confident most sleepers will find the pressure relief to be excellent.

The Helix Twilight Luxe had a strong smell upon the initial unboxing. The mattress smelled for 6 days. This is 0.5 days shorter than the average smell duration of 6.5 days.

Helix has an excellent company score with consumer-friendly terms and conditions. The mattress includes a 100-night trial period and a lifetime warranty. Shipping and returns are both free.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	8.0	100 nights
Warranty	10%	10	Lifetime
Shipping	5%	10	$0
Returns	20%	10	$0
Trust	50%	10	Outstanding
Country of Origin	0%		USA

Comparing 98+ brands tested to date, the average trial period is 176 nights, 76 nights more than Helix offers. Helix also offers a lifetime warranty, an advantage only offered by 39% of all mattresses we test.

Helix has been around since 2015 and based on my experiences with them and feedback from my readers over the years, they are a brand that I have a high degree of trust with.

All Helix mattresses are made in the US.

The Helix Twilight Luxe comes in a single firmness, 8 out of 10, with a firm feel.

This firmness is generally best suited for back or stomach sleepers or heavier sleepers who are looking for more pushback.

Support on the Helix Twilight Luxe is excellent. During our tests, I felt well supported in all sleeping positions. The mattress is equipped with an 8.75″ support layer.

This is 0.83″ thicker than the average support layer thickness of 7.92″, based on all of our tests to date. In order for a mattress to create good support, it needs to provide both support and comfort for the body. The Twilight Luxe does both.

The mattress is equipped with a thicker-than-average comfort layer and a thicker-than-average support layer. Materials within the comfort and support layer are high-performance and high-quality.

Check out the table below to see the sleeper weights and sleeping positions that would be best suited for this mattress.

Sleeper Weight	Stomach Sleeper	Side Sleeper	Back Sleeper
Under 150 lbs.	Yes	No	Yes
150-250 lbs.	Yes	No	Yes
250-300 lbs.	Yes	Maybe	Yes

The pocketed coil unit uses a zoned unit, which creates more support in the middle of the mattress, helping resist middle mattress sagging and better support heavier parts of the body.

All that said, this mattress isn’t for everyone. It has a firm feel, 8 out of 10, where 10 is the most firm. This firmness range is ideal for stomach and back sleepers and less so for side sleepers.

To feel well supported by the Twilight Luxe, you’ll really need to prefer the firm feel.

Based on all of my tests to date, an analysis of the materials, and my subjective experiences, I’m confident that most sleepers will find support on the Helix Twilight Luxe to be excellent.

Design

The Helix Twilight Luxe is a 13.5″ hybrid mattress that comes in a single firmness option—Firm.

Materials

The Helix Twilight Luxe is 13.5″ thick and contains poly foam and a pocketed coil base, wrapped by a quilted cover. From top to bottom, here is a full list of the materials used in this mattress:

• 1.75” quilted cover
• 1.00” memory foam
• 2.00” poly foam
• 8.00” pocketed coil unit
• 0.75” support foam

The table below shows a more detailed look at the exact specifications of the materials used in the Twilight Luxe, according to the manufacturer.

Thickness	Layer Type	Density
1.0″	Pillow Top	1.5 PCF
0.75″	Gel Memory Foam	1.8 PCF
1.0″	Memory Foam	4.0 PCF
2.0″	Poly Foam	1.5 PCF
8.0″	Pocketed Coils (Zoned)	N/A
0.75″	Support Foam	1.5 PCF

The Cover

The Helix Twilight Luxe has a standard Tencel cover with a quilted design. In total, it is 1.75″ thick and contains 1.0” of gel memory foam quilted in the cover.

Sleepers also have the option to upgrade to the GlacioTex cooling cover. The cooling cover contains cooling fibers that help regulate body temperature when you’re lying on the mattress. Regardless of mattress size, upgrading to the cooling cover costs $199.

The Twilight Luxe mattress we tested did not have the GlacioTex cooling cover or the graphite cooling ribbons (aka: CoolForce), designed to pull heat away from the body. These ribbons are only available if you also upgrade to the GlacioTex cooling cover, which we discussed above.

The addition of the cooling cover and cooling ribbons would add an extra $299 to the total mattress cost.

For reference, similar Luxe mattresses (like the Helix Midnight Luxe), which did have the GlacioTex cooling cover, earned a cooling performance score of 10/10 compared to the 9/10 score on the Moonlight Luxe.

The Comfort Layer

The comfort layer is 4.75″ thick, if we include the quilted cover, which is thicker than the average comfort layer. Directly below the quilted cover, we see a 1.0″ memory foam (gray foam) followed by a 2.0″ poly foam (white foam).

The poly foam acts more as a transitional support foam than strictly for comfort.

Helix also offers an optional support layer that you can add, the ErgoAlign support layer. This layer is designed to support spinal alignment, especially along the midsection.

This layer sits directly below the cover and is designed as a supportive foam that helps to reinforce support along the mid-section, thereby allowing less sinkage in the middle of the mattress.

I will say, this layer is quite firm and will not be right for all sleepers. We’ve already heard from some of our readers / viewers who purchased this optional foam upgrade that it made their mattress way too firm, creating an uncomfortable support dynamic.

However, if you really struggle with discomfort caused by too much sinkage in the middle of your mattress then adding this layer can help.

This optional layer costs an additional $199 and is available in the Core and Luxe mattresses. On the mattresses within the Elite collection, this layer comes standard.

The Support Layer

The support layer is 8.75″ thick and made of coils and foam. Directly below the foam of the comfort layer, we see an 8.0″ layer of pocketed coils.

Each of these coils is designed to move independently of each other, with targeted zones that place stronger coils in areas where there is stronger pressure (ie: midsection).

Below the coils is a thin support foam at the very base of the mattress. This mattress is intended to be 0.75″ thick (according to Helix), but we found this layer to be very squished. Our measurement varied from a touch less than 0.50″ to barely 0.75”.

Product Evolution

Helix, as a brand, launched in 2015 with a handful of mattresses that sleepers selected based on the results of an on-site quiz. In 2020, the brand shifted from custom mattresses into a series of collections, starting with the Core collection and the Luxe collection. In 2023, the Elite collection was added as well, providing a total of 3 tiered collections.

In 2024, Helix added the option of ErgoAlign support foam, and in 2025, Helix added the optional graphite cooling ribbons. These two features can help customize and improve any mattress, regardless of what collection it falls under.

For example, you can add the cooling ribbons and ErgoAlign foam to the Helix Moonlight (core collection), the Luxe version, or the Elite version.

In addition, in 2025, Helix redesigned its entire lineup. Here are the major changes from the redesign:

• Aesthetic changes on the covers
• Improved cooling cover (optional on Core and Luxe models, comes standard with all Elite models)
• Slightly different layer stack for foams
• Different / new / updated foams, most notably a new 3.5-4.0 PCF foam that’s included on all Luxe models
