Helix Mattress Ratings

The ratings – based on 100+ consumer reviews gathered using an unbiased, accurate methodology – show how the Helix mattress rates in comparison to the average mattress.

Owner satisfaction B The Helix mattress has 81% owner satisfaction. More.
Durability / longevity C Durability / longevity is not well established but is estimated to be about fair on average (6-year average lifespan). More.
Affordable B Helix is priced $600-$1440 depending on size and whether single or dual comfort. More.
Support B- Reports for inadequate support are almost always limited to softer configurations.
Minimizes pressure points B- Helix's performance on this issue can vary due to customized configurations. Helix tends to be more conforming and pressure relieving than an innerspring bed but less so than a memory foam bed.
Less back pain B- Potential for pain relief appears to be neither a weakness nor a clear strength. (See mattresses and pain relief for general analysis.)
Effective custom- ization B- The Helix mattress is customizable based mostly on body type and sleep position. Consumers seeking a highly soft or highly firm mattress may be disappointed. And topper needs possibly suggest questionable customization effectiveness.
Easy to move on B- The mattress tends to provide low to moderate resistance in regard to changing positions and getting up off the bed.
Motion isolation B The mattress reduces but does not eliminate movement made by one person from transferring across the bed to another person.
Edge support C- Support for sleeping or sitting near the mattress edge is no better than fair – as is true for foam-based beds in general.
No initial off gassing B+ Less than 5% of owners (1 in 20) report a significant and enduring unpleasant initial off gassing odor. More.
No sleeping hot C+ Bothersome heat retention is reported by about 6% of owners (1 in 17). More.
No middle problem C- A configuration with a very different customization for each side may have a less-than-consistent middle area in terms of comfort when lying / spooning on it.
Sex friendly B- Helix has limited bounce but not enough for some. A Helix with dual comfort may have somewhat of a middle problem – see above entry – that may interfere with sex. (See mattresses & sex for general analysis.)
No noise A- Like other foam-based mattresses, Helix is mostly to entirely silent.
No topper needed C About 8% of Helix mattress owners (1 in 13) need to add a topper to the mattress to improve comfort. More.
Heavy person friendly C+ Firmer iterations of the mattress especially appear to be suited for people over 230 pounds.
Light person friendly B- People under 120 pounds may not exert enough pressure on the mattress, especially firmer iterations, to achieve optimal comfort.
Suitable for all sleep positions B If the mattress is customized / configured properly, then an above average level of suitability is possible for all sleeping positions.
Fast break in B- Helix mattresses appear to have a somewhat shorter than average break-in length. More.
Easy / convenient to maintain D+ Helix is one sided and no flip. Head-to-foot rotation may be needed on occasion to prevent and minimize sagging / wear. Rotation for Helix mattresses with different firmness for each side will require each person to sleep on the opposite side they had been sleeping on.
Easy to lift, handle, move B- Weight is about 50-105 pounds depending on size which is about 15% lighter than the average mattress. There are no handles.

Helix Company Ratings

The ratings below – based on consumer experiences and the evaluation of Sleep Like The Dead – show how Helix Sleep compares to the average mattress manufacturer.

Warranty C Helix provides a 10 year non-prorated warranty – very similar to competing mattresses. (See mattress warranties: what to know.)
Return policy A Helix provides a 100-day, no-fee, 100%-money-back trial period. No preparation for return shipment is necessary, and a courier (if available in your area) removes the mattress from your home to be recycled or donated. There is no minimum amount of time the mattress must be kept before being eligible for return.
Customer service B+ Helix customer service is regarded by consumers to be above average but not necessarily flawless.
Marketing accuracy B+ Helix tends to be factual with limited hyperbole and, as a result, performs better on this issue than many of its competitors. The range, accuracy and effectiveness of their mattress customization, however, is perhaps somewhat exaggerated. And 10%+ of owners would likely disagree with the claim that sagging won't occur for a "very long time."
Access to customer reviews D+ Unlike most of its competitors, customer reviews are not sortable or filterable at the Helix website. This makes it difficult to access neutral or negative reviews.
Integrity of customer reviews C Customer ratings in total on Helix's website are about 13% higher than customer ratings in total at independent sources.
Specs disclosed C By disclosing mattress specifications, a company allows consumers to know what they are paying for and helps them to comparison shop. Layer thickness & density as well as mattress weight are often available upon request but do not appear to be on the Helix website.
Time in business C- Helix began selling in August 2015. Buying from a less established company often comes with higher risk because the company has not had the time to smooth the kinks that come with offering a new product and operating a new business.
BBB rating NR Helix Sleep does not have a Better Business Bureau rating which is unusual for a company in business since 2015.
SLTD rating of company C+ SLTD (Sleep Like The Dead) company rating for Helix is determined by averaging the above company ratings.

Key Comparisons

In the charts below, "all beds" refers to all mattresses on the market, and "all foam beds" refers to Helix's main and closest competitors – those mattresses that consist mostly or entirely of foam.

Learn how owner satisfaction is determined.


Helix is significantly less expensive than the average mattress. But it is somewhat pricier than mattresses with basically similar specifications (namely those that are mostly foam with about 10 inches total thickness) likely due to its unique customization.

Durability / longevity

Long-term owner experience data for Helix is mostly unavailable given its two years on the market. Mattresses with mostly similar specifications tend to perform about fair (6-year lifespan) on average. The company improved his base layer density in early 2017 which may provide better durability / longevity than the original iteration.

Topper Usage

About 8% of Helix mattress owners need to add a topper to the mattress (beyond break-in) to adjust firmness. This rate is no better than average which may indicate that the range, accuracy and effectiveness of Helix's mattress customization is questionable.

Heat Retention

About 6% of owners report excessive heat retention at least some of the time. (General analysis: mattresses and sleeping hot.)

Initial Off Gassing Odor

SLTD (Sleep Like The Dead) Company Rating

Helix performs equal to all mattress companies overall but somewhat worse than its main competitors overall based on warranty coverage, customer service, return policy, access to customer reviews, integrity of customer reviews, time in business, marketing accuracy, specifications disclosure, and BBB ratings.

Helix Firmness Analysis

The customization range of the mattress appears to be limited to about medium-soft to medium-firm. In other words, as the chart indicates below, satisfaction is significantly lower for Helix owners seeking a clearly soft or clearly firm firmness level.

* Partial estimate.

After break-in, about 9% of owners find the Helix mattress too firm and about 7% find it too soft. About an additional 14% find the firmness to be acceptable but not ideal.

Helix Mattress Specifications Analysis

The following discusses the construction of the Helix mattress, its thickness and its weight.

Top Layer

The top layers consist of four inches total of foam – 1.8 to 3.0 lb/ft density depending on the customized configuration.

Middle Layer

The middle layer consists of two inches of pocketed microcoils. These are used to improve air flow and provide some bounce. The use of these coils in a foam-based mattress is not especially common.

Base Layer

The base layer consists of four inches of 1.8 lb/ft density foam. This 1.8 lb/ft density is slightly lower than the base layer(s) densities of both foam-based mattresses on average and Helix's main competition on average.

The density of the base layer(s) matters because overall mattress durability / longevity as well as support strength tend to increase as base layer density increases.

Total Thickness

The Helix mattress is ten inches in total thickness. This is about 1.5 inches thinner than the thickness of the average mattress but similar to that of main competitors. A thinner mattress is lower and therefore may be somewhat more difficult to get on and off for people of greater-than-average size or height.

Helix weighs about 55 to 108 pounds depending on size which is about 15% lighter than the average mattress. A lighter mattress may have the disadvantage of not staying firmly in place on its base, but it often has the advantage of being relatively easy to move, lift and handle.
