I received a free Helix mattress for review. The Helix mattress is a completely new take on the mattress in a box concept. Instead of going with a one mattress fits all approach, they focus on customization. So much so that you fill out a questionnaire regarding body type and sleep preferences before you place an order. This hyper customization can be done for each side of the bed if you order a queen or king size mattress so that you and your partner get the optimal feel for your needs.

Helix was started out of similar frustrations with the mattress industry. Instead of creating another mattress in a box, this company sought to address the competing needs of partners who sleep on the same mattress.

Here’s an overview of the Helix mattress



Ordering a Helix mattress is a fun and engaged process. You actually fill out a questionnaire before you place your order. Helix teamed up with some PhD researchers who are experts in bio mechanics to develop ideal mattress specifications for particular body types and sleep preferences that are reflected in the questionnaire. Here’s a snapshot of the beginning of the questionnaire:

helix questions

Further into the questionnaire each person will answer questions about sleeping hot, firmness preferences, etc.  Finally, if the mattress is for 2 people, you will have the option of a transition between each mattress where the foam more gradually transitions to the other preference. Or, a split which means each side of the mattress is pushed together. I chose the transition and found that with the initial opening there was a slight dip where the mattress transitioned but that wet away after a few days.

Helix now offers financing so you can enjoy your mattress now and pay it off over time through Affirm. You can pay off the mattress in 3, 6 or 12 payments.


The Helix Sleep system is made of 3 different layers. Foam, Latex and micro coils which are small springs.


  • 2″ of Dunlop latex
  • ILD Range: 15-32


  • 1.5″ of pocketed coil spring units
  • ILD: 18


  • Poly foam (2″ comfort layer, 4″ base layer)
  • 20-26 ILD / 1.8 pcf (comfort layer), 26-33 / 1.8 pcf (base layer)

These 3 ingredients are then customized based on your inputs in the initial questionnaire


Below is a picture I took when I visited the Helix headquarters in New York City that shows the 3 layers:

I found the Helix mattress to be a little firmer than expected. Although to be fair, I did ask for a firmer mattress it’s just that their level of firmness will be firmer than other companies so know that going in.

Below is a video of me motion testing the right side of the bed.

As you can see there isn’t a whole lot of sink to the mattress. Again I chose the firmer version and you will see more sink the softer you go.


This mattress does a great job with motion transfer and also temperature regulation. Looking at the photo below you’ll notice that the right side looks a bit different in terms of pattern color. In the survey I asked for my side to be cooler than my wife’s side. You can see that there is some sort of cooling gel layer that was added to my side to accommodate this need.

Here’s a quick video of the micro coils


If you are looking for a mattress to accommodate sleepers with very different sleep preferences, this is the ticket. The owners of Helix Sleep are committed to delivering a personalized sleep experience that is backed by science not sales copy. That alone should be reason enough to give them a try. Their generous trial period will give you time to see if they got it right!

                    I think this mattress was designed with proper spinal support as a high priority so in my experience this mattress is firmer than many of the others I tested. However, in the questionnaire you can list your preference for firmness. Just know that if you select a medium level firmness it will be firmer than other mattresses.

                  What is the return policy if the mattress is not a good fit?

                  • admin September 3, 2015 - 12:57 pm Reply

                    There’s a 100 day trial period. From their website: Try our mattress for 100 days and if you don’t love it, we’ll take it back, and refund you in full. We suggest you trial the mattress for at least a month so your body can adjust to a sleep system made specifically for you.”

                  Wow, this looks awesome! I like how they personalize each mattress to each customer – always wondered why the other online brands only had one option for everyone. Quick question: what if I share the bed with my boyfriend?

                    If you get a king or queen size, they can customize each side for each individual sleeper. It is a really nice concept.

                  How would you compare your two sides of the mattress? I know you requested one side be cooler than the other but did you also have both sides have different softness and support as well? I talked to Helix and they explained that they will adjust the order of the top layers (latex, microcoils, and polyfoam) depending on how the customer customizes their mattress. They told me for customers that request the coolest mattress they always put the latex layer on the top which I am guessing is the case for your side and your wifes side must have the polyfoam layer on top. Do you find the two sides feel vastly different due to this change?

                    No, it’s a very subtle difference.

                    There’s not way that I’m aware of that you can change the firmness settings after purchase. So you would be stuck with that firmness setting.

                    The only showroom right now is in NYC so your best bet is to purchase one and try it out at home for 3 months then return if you don’t like it. These companies are very confident in their product and strongly believe that you will end up liking the mattress after you try it.

                  How is the mattress holding up after a while sleeping on it?

                  • admin February 10, 2016 - 5:29 pm Reply

                    I sold this mattress to a neighbor and from what I hear it’s holding up well!

                  Does this mattress smell/have off gasing?

                  • Ben March 20, 2016 - 4:16 pm Reply

                    It does but it’s very faint. I slept on my Helix the night I opened it. If you are especially sensitive to smells, you can let it sit opened in another room for a few days before using.

                  I have a double pillow top mattress that has pillow top on both sides so I can flip it over from time to time and it is about 12 inches thick so I guess this mattress only being 6 or 7 inches thick I’ll have to buy all new sheets,, and can you flip this mattress

                  “Finally, if the mattress is for 2 people, you will have the option of a transition between each mattress where the foam more gradually transitions to the other preference.

I chose the transition and found that with the initial opening there was a slight dip where the mattress transitioned but that wet away after a few days.”

                  Actually, this is incorrect. You can choose to have the entire mattress be the same, but with the needs of the partners combined; or the mattress can be split, with each partner’s sides tailored to their individual needs, then fused together in the middle so there isn’t an obvious split. If the mattress is made entirely the same, they try to accommodate the more important needs of each partner – so if one partner is significantly heavier, the entire mattress will offer more support, for example.

                  We tried a Helix, and found it was really just too firm. I selected the softest available for my side, and it was unfortunately far from what I would call soft. My husband selected medium firm, and there was little difference between sides. Also, we both felt like we were sleeping on an air mattress with too much air. It actually seemed to push up against us, without feeling at all like we were sinking into a comfortable mattress. I didn’t notice any off gassing at all, and the mattress did expand very quickly. The motion transfer was pretty noticeable, but we previously had a memory foam mattress. I thought it was as bad as a typical innerspring mattress. I did a ton of research before ordering, and had really high hopes for this mattress, so I was really disappointed. We wound up with a Luxi.

                  We’ve initiated a return, but their customer service people seem to take their time on that piece. 🙁

                  How does the bed hold up in the long run say after a year? Two years?

                    I can’t speak to the longevity since I only had it for a little while.

                  Can i change it’s firmness and temperature after purchase ? and how can i do that ?

                  • Ben July 12, 2016 - 3:06 pm Reply

                    Yes, you can, you just unzip the cover and switch out the layers. It’s very easy to do.

                  Just curious to know: how on earth would you ship the mattress back? It expands after it comes in a box, but I’m sure most of us don’t have the equipment needed to flatten it enough to fit it in a box again. Do they make you pay for return shipping?

                  • Ben December 28, 2016 - 9:22 am Reply

                    Return shipping is free and they coordinate the return on their end so you just need to contact them and they will guide you through the return process.
