If you’re after a high-quality hybrid mattress that combines pressure relief and support while giving a medium-firm feel, the Helix Midnight mattress might be the right choice. The layers of this bed are stacked to provide a versatile sleep space that should fit many people.
Helix was founded in California in 2015. The company produces a range of mattresses and designs that deliver excellent comfort and quality.
I tested this bed to determine who might benefit from the Helix Midnight the most. In this article, I’ll go further into my findings, explaining what I found when it comes to comfort, pressure relief, support, motion isolation, and more.

Helix Midnight Mattress Performance Ratings
Watch My Helix Midnight Video Review
Who I Recommend the Helix Midnight For:
- Fans of a best-of-both-worlds hybrid design – The Helix Midnight mattress has a classic hybrid design, featuring a coil unit underneath two foam layers. This design allows for a balance of pressure relief and support that I think works for most sleeping positions.
- People with back pain – This mattress has a medium-firm feel and durable coils that should provide sufficient support to the lower back, helping to ease the pain in this area. I think the balance of comfort and support works extremely well for back sleepers.
- Average-weight people – I think that sleepers weighing 130 to 230 pounds should find the Helix Midnight to be comfortable, especially when sleeping on their backs. Those who sleep on their stomach might, however, prefer a firmer bed.
Who I Don’t Recommend the Helix Midnight For:
- Combination sleepers – If you often switch positions at night, you might prefer another Helix model. I found that the Midnight traps you a bit in its top layer, making it a bit tricky to switch positions. I didn’t feel stuck, but I definitely noticed that the bed is slightly lacking when it comes to ease of movement.
- Heavy stomach sleepers – Stomach sleepers weighing above 230 pounds need ample support to prevent the hips from sinking in too deeply. For this reason, I think many stomach sleepers in this group might find the Helix Midnight mattress to be too soft, which could pose issues for their lower backs.
Customer Reviews of the Helix Midnight Mattress
The Helix Midnight rates 4.5 stars out of 5 on Helix’s website. The main negative is that reviewers tend to find it too soft for their liking and feel as though they’re sinking. But overall, users say they’re getting a great night’s sleep and some pain relief.
Testing the Helix Midnight Mattress
Sleep Advisor’s Testing Methodology
Testing the Helix Midnight mattress allowed me to evaluate how it feels in different sleeping positions. This way, I could tell whether or not this mattress would fit a certain group of people based on their weight and preferred sleeping position.
If you look at my video review, you can see me testing the Helix Midnight for motion isolation, edge support, bounce, and cooling. By checking for these preference-based features, I can help you figure out if the Helix Midnight is a good option for couples, hot sleepers, combination sleepers, and people with mobility issues.

Firmness & Feel
Firmness Scale: 6/10
Please remember that firmness is a subjective characteristic and your body type will dictate how you experience a bed. A heavier person whose weight can more easily push through softer comfort and support layers might experience a bed as softer than a lightweight person. The way you are shaped could also play a role here. Consider your weight, shape, and size when evaluating firmness scores.
Mattress firmness is about how hard or soft a mattress feels. Firmness ratings are based on a scale of 1-10, with 1 being the softest and 10 the hardest. I think this Helix mattress is a 6 out of 10, being that it offers a true medium feel that’s not too firm or too soft. There’s a sense of overall support across the entire bed, which should make it a good option for many sleepers.
How Does The Helix Midnight Mattress Feel?
I’m lightweight, so the Midnight felt firmer in some positions, but if you’re anywhere over 130 pounds, I’m sure you experience a true medium feel.
When you first lie on it, you can feel the contouring memory foam layer under the cooling cover. The foam has a medium feel, so you should feel hugged and cradled while the coils do a good job of keeping you from sinking too far.
The cover feels cool and stretchy, which indicates it can take a lot before it shows signs of wear and tear.
Sleeping Positions and Body Types
Helix claims their beds can support up to 1,000 pounds, which is 500 pounds per side. However, one thing to keep in mind is that the Helix Midnight will feel differently depending on how much you weigh.
Side Sleepers
- Lightweight Sleepers – I think the Helix Midnight might feel too firm for people weighing less than 130 pounds who prefer sleeping on their side.
- Average-Weight Sleepers – Side sleepers weighing 130 to 230 pounds should find a good balance of pressure relief and support. My colleague, Emma, who weighs 140 pounds, said she found this position comfortable. However, she added, “If I was sleeping on my side all night, I’d probably prefer a softer bed.”
- Heavyweight Sleepers – Heavy sleepers usually experience this mattress as softer, which makes it a good option for those who like sleeping on their sides.
Back Sleepers
- Lightweight Sleepers – Most lightweight back sleepers should like the support the Helix Midnight provides. The foams keep you aligned and allow just enough sinkage for pressure relief, while the coils keep you supported.
- Average-Weight Sleepers – Average-weight back sleepers should experience some more sinkage for pressure relief without taking away from the support level. I think the foams feel softer in this position but not too soft to make any part of your body sink more than the other.
- Heavyweight Sleepers – Heavyweight back sleepers should sink deeper in the first foam layer, which I think should help relieve pressure build-up. However, this might take away from the support level for those weighing over 230 pounds.
Stomach Sleepers
- Lightweight Sleepers – Stomach sleepers weighing under 130 pounds should feel on top of the mattress, which is excellent when it comes to keeping the spine aligned. My hips didn’t sink at all, so I think the Helix Midnight should feel comfortable for this group.
- Average-Weight Sleepers – Average-weight stomach sleepers might sink deeper into the first layer, but they’re unlikely to bottom out to the coil unit. On her stomach, Emma said she felt decently comfortable but would still prefer a firmer bed.
- Heavyweight Sleepers – Heavy people who like sleeping on their stomachs might prefer a firmer mattress. They would sink too deeply into memory foam, which throws the entire body out of alignment.
Pressure Relief
5/5
The Helix Midnight mattress has two foam layers above the coil unit. The comfort layer is made from memory foam, which is one of the best materials for pressure relief.
We used a pressure map to show weight distribution, which showed us that the Midnight mattress does a good job in this department. This helps keep the pressure off your hips and shoulders if you’re a side sleeper. I give it a big thumbs up here, as pressure relief is among the most important aspects of a good night’s sleep.
Is the Helix Midnight Good for Pain Relief?
The Helix Midnight provides excellent support with enough contouring for pressure relief. Sleepers are unlikely to sink too deeply into the mattress, which should mean good spine alignment throughout the night. The coils support the upper layers and your body, holding all parts equally so that there’s no excess sinkage that could cause back, hip, or shoulder pain.
Back Pain
People with back pain need a mattress that can keep the spine in alignment. I found that the Helix Midnight does this well. The medium feel should allow the spine to remain straight by preventing the hips and shoulders from sinking too far in. That being said, if you’re a heavier sleeper, you should take into account your sleep position when considering this mattress. For example, I think heavier stomach sleepers could wind up exacerbating their back pain on this mattress.

Hip Pain
Hip pain can grow worse if your bed is too soft or too firm. After testing the Helix Midnight, I confirm it provides a good balance of the kind of pressure relief and support needed to alleviate hip pain — though the extent of this relief depends on your weight and body type.

Shoulder Pain
People with shoulder pain should sleep on their back to take the pressure off this area. I think the Helix Midnight is a good mattress for back sleepers, especially those weighing 130 to 230 pounds. Plus, the memory foam should help ease discomfort.
Explore the Best Mattresses for Shoulder Pain.
Support
5/5
The Helix Midnight is a good option for those seeking optimal support, as it’s a hybrid with a true medium feel. After years of testing mattresses, I found that firmer beds are often better for support than those on the softer side. In addition, the Midnight is a hybrid mattress with sturdy coils that help keep the body aligned in different sleeping positions.
Another Helix Midnight quality that stands out is the base layer under the coil unit. I think this gives the bed additional base support and structure, ensuring the upper layers can perform properly.
Motion Isolation
5/5
Motion isolation is important for those who share their bed with a partner, child, or pet. Anyone moving in your bed can disturb your sleep, so having a mattress with good motion isolation can help prevent this.
The Helix Midnight is a hybrid, so it doesn’t have the same motion isolation you’d expect from an all-foam mattress. However, I tested it in several ways, including with a seismograph, and all the tests showed very little movement across the surface of the bed.
Temperature Regulation / Cooling
3/5
Cooling is crucial if you live in a warm climate, but it’s also important for those who naturally sleep hot regardless of the outside temperature. Hybrid mattresses are cooler than memory foam because of the coils that allow more airflow to keep the construction cool.
The Helix Midnight has a cover that promotes cooling, while the coils below will foster that extra airflow. Additionally, you can opt for the optional GlacioTex cooling cover for a slightly higher price. Other than that, there’s not much in terms of cooling, as most of it comes from the airflow in the coils.
Bounce
3.5/5
Although the Helix Midnight has coils, it does lack a bit when it comes to bounce. I didn’t feel stuck in this bed, and I don’t think you’ll feel stuck either. However, movement isn’t a breeze because of the thick foam layer that makes it difficult to switch positions. The ease of movement was somewhere in between for me, but it might be even trickier if you have any mobility issues.
Edge Support
2/5
I must say, I was really disappointed by the Midnight’s edge support, considering the perimeter is reinforced. Sitting on the edge of the bed causes deep sinkage into the comfort layer, and reinforced coils in this area don’t do much to keep you up. When lying in this area, I felt like I was going to slide off the bed at any point.
I wouldn’t recommend the Midnight for seniors and people with mobility issues. The lack of edge support could make it difficult for them to get in and out of bed. If you are a senior, take a look at our list of best mattresses for elderly.
Performance for Couples
3/5
I think the Helix Midnight is a viable mattress for couples, as it has good motion isolation and responsiveness. In addition, the mattress can handle up to 1,000 pounds, which is good if you and your partner are both plus-size sleepers. The bounce, which comes from the coil unit, should be good for sexually active couples.
On the other hand, it doesn’t have the best edge support, so you might want to look elsewhere if you and your partner like to spread out across the entire mattress.

Helix Midnight Mattress: Preference-Based Features
Two Cover Options
This bed comes with a Breathe Knit Cover included. I found this cover to be gentle on the skin and comfortable but not really effective at cooling, which is something to keep in mind if you’re a hot sleeper. For hot sleepers, the company offers an additional cover option called the GlacioTex™ pillow top.
Made in the USA
Helix mattresses are manufactured in the company’s factory in Arizona. Explore more mattresses made in the USA here.
Adjustable Base Compatible
This mattress works with different bed foundations and frames, including adjustable bases for those who want to customize their sleeping experience a bit more.
Luxe Upgrade Available
I think this is a budget option from Helix, offering excellent value for money. However, if you have a higher budget and want a mattress with more bells and whistles, I suggest you look at the Luxe version of the Helix Midnight mattress.
Construction: What’s Inside the Helix Midnight?
The Helix Midnight is 11.5 inches tall and has four layers, including a Soft Touch cover and a bottom cover. The surface is breathable and soft to the touch, which adds to the overall comfort. In addition, you can opt for the GlacioTex™ cover if you’re a hot sleeper, as it’s a cooler option for those who sweat a lot.
The cover is stretchy, and the stitching is durable, so you shouldn’t notice any wear and tear for years. The following are the layers you can find under the cover.
- The comfort layer is made from Memory Plus Foam, which is a unique Helix design. The material is a high-density memory foam blend made to contour the body and provide a comfortable cushion for pressure relief.
- The transition layer is made from high-grade poly foam. This material offers pressure relief and ergonomic support while providing a transition layer between the memory foam and coil unit.
- The 8-inch coil unit is located below the poly foam layer. The coils are made from steel and are individually wrapped to help minimize motion transfer across the mattress. This bed has enhanced edge support lengthwise, which means the thicker-gauge coils are only added to the left and right side of the bed.
- The base layer is made from DuraDense Foam and sits at the bottom of the Helix Midnight mattress. This foam is made to provide a supportive base and durability.
Unboxing & Off-Gassing
The Helix Midnight mattress comes rolled in a box, which makes it easy to move from your door to the bedroom. Once you have it near the bed frame, open the box and place the rolled mattress on the frame. Remove the plastic, and the bed will unroll.
As is usually the case with bed-in-a-box mattresses, it takes a while for the bed to decompress and reach its full size. The Helix Midnight should reach its full size in about 45 minutes.
When it comes to off-gassing, I noticed a slight odor when we first removed the packaging. The smell should dissipate in a week, but you can speed up the process by airing the mattress in a well-ventilated room and without any bedding.
Certifications
- Eco-Friendly Certifications – The foams in this bed are CertiPUR-US® certified. CertiPUR-US® is a third-party program that ensures the foams meet rigorous health and safety standards. This means they don’t contain harmful substances like ozone depleters, PBDEs, heavy metals, formaldehyde, and phthalates. They should also have low volatile organic compound (VOC) emissions. This bed is also GREENGUARD Gold certified for low chemical emissions.
Coupons, Trials, Warranties, and Shipping
- Shipping – Shipping is free within the United States. Helix ships mattresses to Canada for an additional fee.
- White-Glove Delivery – Helix offers an Old Mattress Removal service, but this is currently suspended due to COVID-19 safety concerns. However, this service is still available in California.
- Trial – Helix offers a 100-night trial for customers to test how the Midnight mattress performs and fits their needs.
- Warranty – This mattress comes with a 10-year warranty.
- Return Policy – Returns are free within the 100-night trial. One thing to keep in mind is that only two mattresses can be returned per household or customer.

Frequently Asked Questions
What kind of mattress is the Helix Midnight?
The Helix Midnight is a hybrid mattress that features a combination of 8-inch coils, memory foam, and poly foam in its construction. I think this hybrid construction gives a balance of support and pressure relief, along with qualities like motion isolation and responsiveness.
Where can I buy a Helix Midnight mattress?
You can buy a Helix Midnight mattress online directly from Helix. They’ll box up the mattress and send it to your address so that you don’t have to handle transporting it to your home.
Where can I try out a Helix Midnight mattress?
There are two ways to try out a Helix Midnight mattress before you make it a permanent fixture in your bedroom: you can test it at home for a 100-night trial, or you can lie down on it inside one of Helix’s partner showrooms.
The 100-night trial begins after you’ve ordered your Helix Midnight. You then have 100 nights to snooze on the mattress and decide if it’s a good match for your sleep needs. If not, you can return the mattress to Helix for a full refund—they’ll even coordinate the mattress pickup for you.
As mentioned, the other option is to visit one of the brand’s partner showrooms, where certain mattress models are displayed and free to test out. Not every Helix model is available at these showrooms, but the Midnight is often featured. However, because a quick lie-down (or even a quick nap) isn’t as thorough of an experiment as actually sleeping on a mattress for multiple nights, I recommend taking advantage of the 100-night trial.
Is the Helix Midnight hot?
I didn’t notice the Helix Midnight runs hot, but I also didn’t notice any standout cooling. The mattress has a breathable cover, and there’s an option to choose the GlacioTex™ cooling cover to further enhance the cool-to-the-touch feel. In addition, the upper layers are unlikely to overheat thanks to the coils that allow air to circulate.
Is the Helix Midnight too firm?
The Helix Midnight is rated 6 out of 10 on our firmness scale, which means it has a true medium feel. I think this firmness level should fit many sleepers, as it allows some sinkage to prevent pressure buildup without taking away from support.

My Verdict
Testing the Helix Midnight mattress was all fun and games, given the balanced and comfortable feel. I think this mattress is a great option for many people thanks to its excellent features, such as a breathable cover, durable coils, two foam layers, and an optional cooling cover.
The medium feel makes it a good match for people with back pain, as well as average-weight sleepers in general and some lightweight and heavy folks.
In addition, the Midnight has an affordable price, a long trial, and a 10-year warranty. All of Midnight’s memory foam layers are certified as free of chemicals and toxins, so the mattress is a safe option for consumers. Overall, the Helix Midnight earned a 4 out of 5.
