Helix Midnight Mattress Overview

For those of you who are new to the online mattress space, Helix Sleep is one of the most popular bed-in-a-box companies on Earth, competing with the likes of Casper, Leesa and Purple Mattress. However, compared to most online brands, Helix takes a slightly different approach. Instead of offering a good-better-best lineup, Helix offers over ten different models in order to specifically accommodate a wide range of people, budgets and sleeping preferences. 

This review takes a detailed look at the Midnight mattress, which is the company’s most popular model. The model is especially comfortable for combo sleepers who find themselves moving around from their sides, backs, and stomachs all night. It’s firm enough to provide support for back sleepers yet soft enough to give side sleepers pressure relief. We’ll get into more specifics as you keep reading this Helix Midnight Mattress review. Here are our jump-to links so you can easily navigate to any section of this review.

Now that you have a little background about the Helix Midnight let’s dig into the nitty-gritty details you should know about the bed. Here’s a quick overview of the subjects that we’ll be covering. Click the links to jump to the appropriate section in this Helix mattress review:

Helix Midnight Mattress Construction & Design

Like the other standard Helix models, the Midnight mattress is 12” thick. The bed is comprised of four different layers. Below is a quick summary of each layer, starting from the bottom.

Construction of Helix Midnight
  • DuraDense Foam – Supportive, dense foam which serves as the base of the bed.
  • Individually-Wrapped Coils – Form the true support framework for the mattress.
  • High-Grade Polyfoam – Medium firmness transition layer.
  • Memory Plus Foam – A proprietary foam created by Helix that serves as the comfort layer for the Midnight mattress.

Now you may be wondering what differentiates all the different Helix models. After all, the company offers six different standard mattresses, six different Luxe mattresses and one Plus mattress specifically geared towards heavy people.

Well, the answer lies in the transition and comfort layers of the standard beds. Depending on which model you select, these layers will change slightly to better match-up with your sleep style. In this case, the Midnight mattress uses a medium IFD transition foam and Memory Plus Foam comfort layer in order to appeal to a wide variety of sleepers. The Midnight mattress is supposed to be the company’s “safe pick.” In other words, it’s not too soft or too firm, making it universally appealing.

Lastly, we should mention that the foams used within the Midnight mattress are CertiPUR-US and OEKO-TEX Standard 100 certified. Without getting too scientific, this essentially means the bed is safe to sleep on. Also, just in case you were wondering, the Midnight mattress is made in the USA.

Helix Mattress Cover

Wrapping the Helix Midnight mattress is the company’s Soft-Touch cover. It’s designed to be stretchy and breathable. The cover is not removable, which means you’ll have to rely on spot cleaning if it somehow gets dirty. If you’re worried about stains, spills or other grime, you may want to consider purchasing the Helix Mattress Protector.

How Does the Helix Midnight Mattress Feel?


The Helix Midnight mattress has what we consider to be a neutral-foam feel. This means the feel of the comfort layer sort of lands in-between memory foam and latex foam. It’s soft and comfortable like memory foam, but it’s also more responsive, resembling latex foam to a certain degree. All in all, our team finds the Midnight mattress to be quite comfortable. We don’t envision many sleepers throwing a fuss regarding comfort or feel.

As far as firmness goes, the Midnight mattress lands somewhere near the middle of the scale. As we stated earlier, this bed is designed to tow the line between plush comfort and firm support. We give it a medium rating (or 5 out of 10).

Pressure Relief

The Helix Midnight is soft and pressure relieving, yet it also provides a good level of support. For those who are primarily side sleepers, though, we would recommend one of Helix’s other mattresses for more pressure relief, like the Helix Sunset. This one is a little softer to provide even more pressure relief.


In our opinion, the Helix Midnight mattress sleeps temperature neutral. This goes for all Helix mattresses, and to be quite frank, most online beds in general. There are only a handful of beds we’ve tested that we consider to be actual cooling mattresses.

To be clear, by temperature neutral, we just mean the bed doesn’t actively cool you down as you sleep, but we also don’t think it will be the primary reason why you sleep warm either. It’s important to note that sleeping temperature is affected by a wide range of factors. Your mattress isn’t the only element you should consider. We’re talking about other considerations such as your home climate, the material of your sheets, what type of comforter you use, etc.

Is Helix Midnight A Good Mattress For Couples?

Yes, the Helix Midnight is an excellent mattress for couples. Not only does the bed find a nice balance between comfort and support, which will hopefully help couples with different sleeping preferences compromise, but the bed also performs well in the areas of motion isolation and edge support.

Motion Isolation

The Helix Midnight mattress isolates motion extremely well. Although the bed does utilize coils, which gives it a little bounce, our team found the mattress does a good job of limiting cross-bed motion. As such, if you happen to share your bed with an active sleeper, you should be able to get a restful night of sleep despite the commotion on the other side of the bed.

Edge Support

The Helix Midnight mattress also provides excellent edge support. In fact, all standard Helix models include a reinforced perimeter of coils to ensure sleepers remain supported near the edges. This means you and your partner will be able to spread out and utilize the entire surface area of the mattress.

Sleeper Type Analysis For The Midnight Mattress

To begin this section, we should mention the obvious – that every sleeper is different. There’s no one size fits all mattress. The same bed can feel drastically different to various people, depending on their body type, weight and primary sleeping position. It’s important to keep this in mind while shopping for a new mattress. Just because a particular brand markets their bed as “extra plush” or “luxury firm” doesn’t mean it will be the right fit for your particular situation. In the following sections, we’ll discuss how the Midnight mattress accommodates different sleeper types and body sizes through the lens of an average size sleeper (~150-225 pounds).

  • Side Sleepers
    Good For

    When it comes to side sleeping, the Helix Midnight mattress is a good but not great option. Allow us to explain – primary side sleepers typically prefer softer beds that are extremely gentle around their hips and shoulders. If you fall into this category, you’ll likely prefer the Helix Sunset mattress. This is the softest model the company offers.

    However, as we mentioned earlier, not every side sleeper is the same. If you’re the type of side sleeper who prefers a slightly firmer yet still comfy mattress, then the Helix Midnight is likely a solid fit. The bed has a balanced/supportive feel, but it still has a little give in its comfort layer in order to accommodate the pressure points of side sleepers.


  • Back and Stomach Sleepers

    It’s the same story for back and stomach sleepers as it is for side sleepers (i.e., good but not great option). Similar to side sleepers but on the opposite end of the spectrum, back and stomach sleepers typically prefer firm beds that provide ample support under their lumbar region.

    In this case, we’d recommend the Helix Dusk or Dawn models if you’re the type of back or stomach sleeper that does indeed prefer firmer beds. However, if you happen to prefer slightly softer yet still supportive mattresses, then the Helix Midnight is a fine option.

  • Combo Sleepers
    Good For

    When it comes to combination sleepers who rotate between their side, back and stomach, we think the Midnight is the ideal model the company offers. It’s positioned perfectly between plush/comfort and firm/support. After all, this is likely why the Midnight is the company’s most popular mattress. To put it simply, the bed comfortably accommodates all sleeping positions.

    In addition, our team found it easy to move around on the bed. The coils in the mattress, along with the responsive comfort layer, make it effortless to switch between positions. This means you won’t get that stuck-in-the-mud feel as you do with some memory foam beds.


Body Type Analysis

  • Heavy Individuals

    The Helix Midnight mattress will work for heavy people (~225+ pounds). The coils in the mattress, along with the other layers, provide solid support. With that said, the Midnight is not the ideal option the company offers for larger body types. They also offer six different Luxe models, which are slightly thicker than the standard models. Last but certainly not least, the company offers the Helix Plus mattress, which is specifically designed and constructed for heavy people. If you weigh over 250 pounds, we’d urge you to strongly consider this model over the Midnight.

    In addition, please keep in mind that beds typically feel softer to heavier individuals. As such, a person who weighs over 250 pounds will likely feel the Midnight mattress lands closer to a medium-soft (or 3.5 out of 10). This is due to the fact that larger folks apply more pressure on the mattress and thus sink-down further into the comfort layers. Given this information, the Midnight mattress is likely not a good option for heavier back and stomach sleepers.


  • Petite To Average Individuals

    The Helix Midnight mattress will certainly work for small to average-size sleepers. However, there is a small caveat (pun intended). Similar to heavy people, but in the opposite way, beds typically feel firmer to lightweight individuals. As such, we wouldn’t recommend the Helix Midnight to petite side sleepers. Instead, if you fall into this bucket, we’d recommend the Helix Sunset model.

Helix Midnight Pricing

The Helix Midnight mattress is priced very affordably. In fact, it’s cheaper than a lot of all-foam beds on the market. Given its hybrid design, we think the Helix Midnight, along with the other standard Helix models, is an excellent value. Here is a look at the MSRP by size.

Twin $749
Twin XL $849
Full $999
Queen $1,099
King / Cal King $1,399

Helix, like most other bed-in-a-box brands, is very aggressive when it comes to sales and discounts. In most cases, you can expect to receive $100-$200 off your purchase. That means a queen size come checkout will likely drop below the $900 mark. Be sure to check the green discount box on your screen for current pricing and promotions.

Helix Midnight Mattress Review Verdict

There’s a reason why the Helix Midnight is the company’s most popular mattress. It manages to toe the line between comfort and support, allowing it to accommodate a wide range of sleepers and body sizes. If you’re the type of person who doesn’t want a particularly firm or soft bed and tends to shift between positions throughout the night, you’ll be hard-pressed to find a better mattress. It’s also tough to argue with the price tag. At under $1,000 for a quality hybrid mattress, you really can’t go wrong. All in all, the Helix Midnight gets two thumbs up from our team.
