Our Verdict

Offering a combination of memory foam and coils, we think that if you’re serious about getting a good night's sleep, you won’t do better than a Helix mattress.


  • Ideal for customers who don’t know which firmness is for them
  • Great for hot sleepers
  • Excellent value for money


  • Sleepers who want a traditional memory foam feel
  • Users who don’t enjoy responsive mattresses thanks to the coils
  • It can take over 10 days to deliver

We’ve updated our original Helix mattress review, and we like what we found. Helix bases its whole ethos on making sure you find the best mattress online for you, specifically. To help you decide on the right mattress, users are invited to take a sleep quiz, which details their sleep preferences as well as height, weight and preferred firmness. 

The Helix is made up of a combination of memory foam and pocketed micro coils and is delivered in a standard ten-inch depth. The mattress consists of several layers which are interchangeable based on how you answer the questionnaire. 

So it’s a highly bespoke service, but one that doesn’t cost an excessive amount, and is the best cooling mattress for people who want more custom levels of firmness.

Helix Mattress review: Prices and value

Considering how customizable Helix mattresses are, the prices offer extremely good value. In fact, the RRP of the Helix is actually lower than other major mattress-in-a-box brands on the market. Helix also has regular money off and free gift promotions throughout the year so you’re always able to find a bargain. 

The RRP of the Helix mattress ranges from $600 for a twin to $1149 for a Cal King. Pricing is as follows: Twin: $600 | Twin XL: $700 | Full:$ 850 | Queen: $999 | King: $1249 | Cal King: $1249

  • Suitable for all sleep positions
  • Good support zone
  • Good for heavier sleepers

Helix has something for everyone, including comforters, sheets, protectors and pillows for sleeping. Because the Helix is a blend of foam and coils it has the perfect balance of comfort and support meaning you get the contour you expect from a memory foam mattress with the support to relieve pressure points from the coils. 

Helix also takes into account that heavier sleepers need extra support and have a model that includes thicker support coils so it supports a larger weight with the same comfort and support levels. 

The coils also mean that you won’t sleep hot on the Helix because there is adequate room for airflow plus if you are a hot sleeper you can purchase an additional Ultra-Cool Cover. It’s not quite as effective for hot sleepers as the Purple Mattress, but still very good.

Helix Mattress review: Features

  • Fully customizable 
  • Motion isolating
  • Can be used on any foundation

Helix puts the power of designing your ideal mattress in your hands. They come in the traditional sizes twin, twin XL, full, queen, king, and California king with a standard 10” depth. 

The Helix also caters to the larger sleeper thanks to an additional level of support on the Helix PLUS (each mattress has a different name) which can easily accommodate weight over 200lbs. 

The combination of pocketed micro coils and foam means that you get very limited movement when you move around on the Helix. There is however a lack of edge support meaning if you like to sleep close to the edge, you may feel as though you’re not fully supported in the bed.

To boost your in-bed comfort and support even further, consider using one of the best bed toppers on top of your mattress.

The Helix mattress range is split into firmness bands, and the website gives you a good idea of what firmness is right for you, dependent on the way you tend to sleep, and the way your body behaves at night.

Helix is a mattress in a box product, so delivery is easy. It's also free, which is good for saving on costs. However, boxed mattresses need a period of time - usually two weeks - to settle after being unboxed, so take this into account when you buy.

We were impressed with the range of features and help sections on the Helix site. It can be a little overwhelming, and is occasionally geared towards sales, but most of the information is well worth looking at before you buy.

Helix Mattress: User reviews

Helix doesn’t have a lot of reviews on its website but those who have rated it online have given it high stars thanks to its excellent value and high comfort levels. Users also highlight the good customer service that Helix offers especially for those customers who were unsure about buying a mattress online. 

Should you buy the Helix mattress?

The Helix mattress is priced between $600-$1249 which we think is an exceptional value for the benefit of having a fully customized mattress. Helix is a great mattress to purchase if you’ve never strayed into the world of online mattresses before - or even if you’re new to memory foam. 

Because it’s fully customizable it doesn’t matter if you prefer to sleep on your side, back stomach or even if you prefer to starfish across the entire bed - this mattress will work for you. 

We do recommend that you’re completely honest when filling in the quiz - even if you don’t enjoy sharing the details of your bathroom scales because without honesty you could end up with a mattress that isn’t uniquely yours, and this is where you can potentially run into problems.
