Helix Mattress Review: Overview

Helix Sleep has an interesting concept compared to a lot of online beds. Rather than offer just one mattress model, they make over 10, but we actually think they do a good job of keeping it simple for the consumer.

The above video was produced with the help of our parent company, RIZKNOWS LLC. For even more information on Helix, though, check out the rest of the review below.

Helix Sleep Company Policies

Like most of the mattresses that we’ve reviewed, the Helix mattress ships for free in a box that’s about 4 feet tall. All you have to do is drag the box into your house and remove all of the packaging.

The whole process takes about 5 minutes from start to finish, and is actually sort of fun. We’ve reviewed dozens of mattresses sold online and the whole unboxing process never gets old to us.

Unboxing the Helix mattress

Once you’ve removed the plastic wrapping and set the Helix mattress on its foundation, you should allow the bed about 24 hours to fully decompress. For the record, you have to do this with nearly all bed-in-a-box mattresses, since they’ve usually been roll up in plastic for several days.

Helix has a 100-night trial period where you can test out the mattress in the comfort of your own home, pretty much risk-free. If at any point during the trial period you decide that the Helix mattress is not for you, call Helix up and get a full refund. Really, there is no catch. It’s as simple as that.

Just to be clear though, it’s not just Helix that holds this policy. Plenty of the other mattresses that people are buying online come with risk-free trial periods. Both Casper and Purple have the exact same policy.

You are basically renting a mattress for 3+ months without making a firm commitment. If you do decide to return the bed, Helix even sends someone to your house to pick it up (free of charge) so that there are no return fees whatsoever.

In the event that you keep your Helix mattress, it comes with a 10-year warranty to protect against manufacturing defects, among other things.

Helix Mattress Price & Coupon Code

The Helix mattress is moderately priced compared other bed-in-a-box mattresses, especially when you consider Helix gives you more options. Here’s a pricing breakdown:

SizePrice (MSRP)
Twin XL$700
King / Cal King$1,245

As you can see, prices aren’t crazy, but Helix is not a super cheap budget mattress or an imported mattress that you buy on Amazon.

Helix does, however, tend to offer promotions during major holidays—they basically play the coupon game just like any other mattress company. You can check HelixSleep.com for current discount and promotions. We also have an evergreen coupon linked here on the page that should work for you year-round.

Helix Sleep Quiz & Mattress Models

One of the more unique things about Helix is that they run consumers through a Sleep Quiz on their website that matches them with a suitable mattress. The quiz takes about a minute to complete, but it allows Helix to provide a more accurate recommendation to you. Here’s a look at the quiz.

Helix Sleep Quiz

Helix actually makes nine mattress models, but the difference between them is subtle. They have six core models that only differ in two areas: (1) firmness and (2) support. The other three models are special—we will get to these in a second.

The Midnight model, for example, is a medium on the softness/firmness scale and is designed for medium and petite individuals in terms of support. The Dusk model is essentially the same mattress only it has more support (the firmness is about the same).

As for the other three special models, Helix makes Nightfall, which is specially designed for big and tall individuals. This mattress is 12″ thick and extra supportive.

They also make Dual Balanced and Dual Extra, which are split mattresses with a softer side and a firmer side. The only real difference between the two is related to support.

What is the Helix Mattress Made Of?

This will depend on which exact model you select, but for six of the nine models, the construction is fairly similar. The six core models are all 10″ thick with 6″ pocketed coils and 4″ of foam.

The Helix Midnight mattress (medium firmness / medium support).

Helix varies the density and firmness rating of the foams in order to achieve more/less support and more/less firmness. The four different foams used within Helix mattresses are memory foam, polyurethane foam, Helix Dynamic Foam, and DuraDense Foam (aka Support Foam).

Not all of the beds have all of the foams—some just have three of the four—but it really won’t matter much for the consumer. The foams are just levers that Helix can pull in order to offer nine different models (and hopefully have a mattress for everyone).

The Helix Nightfall mattress (medium-firm firmness / extra support).

The image above shows the Nightfall mattress, which is extra supportive and also is thicker and more expensive than the other Helix beds. It’s 12″ thick with 8″ coils and four different types of foam. The bed itself is about a medium or medium-firm on the firmness scale, but is very responsive.

Overall Feel

This will differ somewhat between the nine mattress models, but for the most part, the Helix mattresses have more of a soft foam or neutral feel. There’s no overwhelming memory foam feeling, even though several of the beds incorporate memory foam.

The beds do not feel like your traditional innerspring mattress with a pillow top.

Owen approved!

If you’re looking for more of a softer foam bed, but you want the support, responsiveness, and durability provided by coils, that’s pretty much a summary of all nine Helix mattress models. Of course, the exact support and firmness of the bed will vary from model to model, but the overall feel is soft, neutral, and accommodating.

Cover and Cleaning

Helix mattresses all have two covers. There’s a bottom cover that, from what we can tell, doesn’t do much (if anything) for you, practically speaking.

Then you have a top cover that’s removable and machine washable. It’s also soft to the touch and has ridges, which are really nice. Just so you know, most bed-in-a-box mattresses do not have washable covers. Off the top of my head, the Eve mattress and Novosbed are the only other two that I can think of right now.

Helix recommends that you wash the cover in cold water with normal detergent. As for drying, they say you should tumble dry on low heat or leave out to air dry.

Removable, washable cover

Helix also sells a cover with a phase-change material woven in. I won’t bore you with how the technology works, but the end result is a cover that’s somewhat cool to the touch and helps to ensure you don’t warm up excessively at night. It won’t make Helix the best cooling mattress ever, but it will be better than nothing for a lot of hot sleepers. The cover is cool, but not ice cold like that of the Brooklyn Bedding Aurora.

Helix Ultra Cool Cover

Generally, we’re not a huge fan of companies up-selling consumers, but in this instance, offering an optional cooling cover makes sense. While some people sleep excessively hot, others sleep cold. And by selling a separate cover, Helix has an option for hot sleepers without alienating cold sleepers. You can see the Ultra Cool Cover on Helix’s website.

Is Helix Good for Back and Stomach Sleepers?

Short answer: yes. Back and stomach sleepers generally prefer firmer mattresses. They help to keep proper spinal alignment and ensure that you don’t wake up with an achy lower back.

Because softness/firmness is subjective based on your weight, the best mattress for back sleepers and the best mattress for stomach sleepers will be different person to person.

For medium and petite size back/stomach sleepers, we recommend that you check out the Midnight, Dusk, Twilight, and Dawn models. Midnight and Dusk are about a medium on the firmness scale and Twilight and Dawn are noticeably firmer.

For heavier individuals, you should stick to the Nightfall mattress. Even though the other six Helix mattresses have coils, Nightfall is specially designed just for heavier folks.

What About Side and Combo Sleepers?

Yes for here as well. If you want maximum pressure relief, check out the Sunset model, which is the softest and most pressure relieving mattress that Helix makes. Moonlight adds a little more support, but is also a softer mattress.

If you’re a strict side sleepers, you’re primarily looking for pressure relief, but you still need a supportive mattress. And the heavier you are, the more support you need.

For combination sleepers, Helix makes it easy to switch sleeping positions at night. The combination of coils, responsive poly foam, and Helix Dynamic Foam means you do not get that dreadful stuck-in-the-mud feeling. Here’s a look at just how responsive the beds are:

Responsive, but still pressure relieving.

Responsiveness will depend on the exact construction of the mattress. If the top layer is memory foam, the bed will be a little slower to respond, but there’s still no stuck feeling. The bed just happens to be pressure relieving and will have a slight memory foam feel.

Can Heavy People Sleep on a Helix Mattress?

Petite and medium size individuals have it easy—nearly every mattress will work for them since they don’t put all that much stress on the bed.

Heavier folks usually have a tougher time finding an appropriate mattress because that mattress must check a lot of boxes. Not only does it need to fit their preferred sleeping position, but also it has to provide extra support for the long term.

Here’s a look at Helix’s video about the Nightfall mattress.

Luckily, Helix is well aware of this dichotomy and created the Nightfall mattress solely for heavier folks. As mentioned above, it’s 12″ thick in total, uses 8″ pocketed coils, and has four layers of foam. While you can’t customize the Nightfall mattress at all, it is very accommodating and comfortable as is, not to mention extra supportive.

Is Helix Sleep Recommended for Couples?

Yes! Helix is one the best mattresses for couples because they give you so many options. As we’ve mentioned, you have six core models to select from, one big & tall model, and two split models, making nine different models total.

For most couples, the six core models should be more than enough to choose from, but if your partner and you sleep completely different, you can opt for the Dual Balanced model or Dual Extra model. These are about $200 more than the core models, but they come with split firmness levels. On one side you have a softer feel and on the other is a firmer feel.

This is great if one partner is a strict side sleeper and the other is a strict back or stomach sleeper. There are very few companies that offer this split option. About the closest that you can get is a split king where there’s actually separate beds; we think the Helix solution is better.

Couples should also pay attention to motion isolation and edge support with a new mattress.

Motion isolation refers to how well the bed deadens motion. A bed that’s efficient at motion isolation will be helpful if your partner is active in their sleep or tends to get up for a midnight snack.

Surprisingly good at isolating motion

Despite having coils, Helix is actually quite good at limiting motion transfer, as you can see in the clip above.

Edge support is also key for couples. This refers to how strong the edges of mattress are. Edge support is more important for couples sleeping on a smaller mattress such as a queen or a full.

helix mattress review edge support
JD has really been on edge lately.

Edge support will be better with the firmer two models and worse with the softer two models. In general, softer coil mattresses just tend to have worse edge support than their firmer counterparts.

The edge support on Midnight and Dusk isn’t great, but it’s not terrible. The bottom line is that edge support is not a reason to get a Helix mattress. If you’re truly worried about it, go for a king size.

Helix Mattress Review: Verdict

There’s a heck of a lot to like with Helix, and it’s hard to poke holes in their business model. It makes a lot of sense to run consumers through a questionnaire to match them up with the appropriate mattress. And the mattresses themselves are well-made, durable, and very comfortable.
