Helix Midnight Mattress Review

Materials: Foam and coils

Firmness: 6/10

Warranty: 10-year limited warranty

Trial Period: 100-night sleep trial

Price Range: $600–$1,349

The Mattress Nerd’s Take:  When Helix says they have “mattresses designed for every body,” they literally do mean every “body.” The mattress company sells a wide range of beds—more than a half dozen versions—from soft to firm, designed for every sleep position (side, back and stomach). They even have the Helix Plus mattress for the big and tall. So why are we reviewing the Midnight? Simply put, it’s the brand’s most popular, hybrid bed, with a medium firmness level that appeals to most all folks, especially side sleepers. It’s not too soft and not too firm, and it could be right for you. Keep reading to find out why.

Who is the Helix Midnight Mattress Best For?

Body Type: BACK SLEEPERS STOMACH SLEEPERS SIDE SLEEPERS
Lightweight (< 130 lbs):  4 3 5
Average weight (130 – 230 lbs): 4 3 5
Heavyweight (> 230 lbs):  3 2 4

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Back Sleepers

The Midnight offers a great balance of comfort and support for back sleepers. Neither our lightweight tester (< 130 lbs.) nor our average-weight tester (130–230 lbs.) felt any pressure while lying on their backs. This bed should also work just fine for heavyweight back sleepers, but ultimately Helix has a bed designed especially for them—the Helix Plus.

Stomach Sleepers

Unfortunately, for stomach sleepers, we found that the Helix Midnight didn’t quite pass the test. Our mattress testers of all weights felt as if their hips were dipping too far down into the mattress, meaning their spines were bowing out of alignment, which can cause pain. So, strict stomach sleepers of all weights might want to try the firmer Helix models: for instance, the Twilight or the Dawn.

Side Sleepers

The Helix Midnight was actually designed for side sleepers of all weights. One reviewer writes: “I have always slept on my side and woken up with shoulder or hip pain through the night, but not with the Helix.” The middle layer of the bed supports your body contours, allowing the shoulders and the hips to cushion into the bed. This contouring also promotes lateral spinal alignment, and when your spine is supported correctly, you have less back pain and achiness in the morning. Note that Helix also offers softer models, the Sunset and the Moonlight, which might be more comfortable for some side sleepers who require more pressure-point relief.

Combination Sleepers

You’ll see in the construction section below that the Helix Midnight has a layer of Memory Plus Foam right on top. This material slows the bed down when it comes to responsiveness, meaning it may be hard for combination sleepers to change positions throughout the night. Thus, if you enjoy sleeping more “on top” of your mattress so you can easily roll around, you may want to choose a different bed with less of a classic memory foam feel.

How Does the Helix Midnight Mattress Feel? 

Responsiveness, Bounce and Ease of Movement 

The Helix Midnight has more of a classic, slow-to-respond feel, so much so that one reviewer reported the foam top to be “reminiscent of a Tempur-Pedic mattress.” So it’s not going to be as easy to maneuver around on (an important note for those with mobility issues). However, according to our Nerd testers, once you get in your favorite sleep position, the bed is “very cozy.” 

How Firm Is This Mattress?

At MattressNerd, we rank mattresses from 1 to 10 on the firmness scale, with 10 being the firmest. And we scored the Helix Midnight as a 6 out of 10. I heard one of our lightweight testers say, “This bed is the perfect medium feel.” Keep in mind that people of different weights will register firmness levels differently: Lightweight folks (130 lbs. or less) feel mattresses to be softer, as these lightweights hover on the softer top layers. And heavyweight folks (230 lbs. or more) tend to quickly push through the soft layers to feel the firm base layer at the bottom.

Does It Sleep Hot? 

The Helix Midnight possesses two qualities to help keep you cool at night. First, it features a soft, breathable cover, and next, it’s a hybrid bed. This means that the individual coils at the base promote airflow and breathability throughout the mattress. However, the Memory Plus Foam up top is not gel-infused, which means it may not sleep as cool as hot sleepers would like. So, to max out cooling qualities in a hybrid bed, look for one with both gel-infused foam and individually wrapped coils.

Is the Helix Midnight Mattress Good For Couples? 

Motion isolation is the mattress’s ability to reduce and limit the spread of movement from one side of the bed to the other. This is important if you have both a sleep partner and midnight snack cravings. When you get up for your snack, you don’t want to disturb your slumbering partner on the other side of the bed. We tested the Helix Midnight in our lab and found very little vibration moving across the surface of the mattress. This is due to the top layer of Memory Plus Foam, which greatly cuts down on motion transfer.

How’s the Edge Support? 

I felt especially secure sitting and lying along the edges of the Helix Midnight. Edge support is important if you enjoy doing things on the edge of your bed like reading, applying lotion or tying your shoes. You don’t want to feel as if you’re collapsing to the bed frame or like you’re about to slide into the floor. You’ll see in the construction section below that this mattress features a layer of individually wrapped coils that provide extra reinforcement around the perimeter of the bed, which means excellent overall edge support.

Construction: What’s Under the Surface?

The Helix Midnight consists of high-grade materials, from its soft breathable cover on top, to its support layer of individually wrapped coils, down to its durable base foam. All of these materials add up to a thick, 12” tall bed featuring excellent edge support, great pressure relief and support where you need it the most.

Layer #1: Soft Touch Design cover: This cover feels soft to the touch and has a light stretch. The best part: It’s optimized for airflow to help keep you cool at night.

Layer #2: Memory Plus Foam: Beneath the cover, you have about a 2” comfort layer of Helix’s proprietary Memory Plus Foam, which has a medium feel. This top layer is designed to relieve pressure on the joints, such as the shoulders and the hips.

Layer #3: Responsive Polyfoam: This 2” transition layer provides ergonomic support and cushioning. It also transitions from the memory foam on top to the coils beneath. With any mattress, you don’t want to sit down or lie down and feel the coils underneath. So this extra layering of foam on top prevents the bed from “bottoming out,” or allowing the sleeper to feel the dense coils.

Layer #4: Individually Wrapped Coils: This layer of hundreds of individually wrapped coils cradles your body and provides added support. It also has a reinforced perimeter for added edge support, which is great for couples who like to spread out and lie along the edges of the bed. Individually wrapping each coil also helps cut down on motion transfer, so you won’t disturb your partner if you’re a restless sleeper.

Layer #5: DuraDense Foam: The bottom layer of the bed provides base support and durability for the entire mattress. At Mattress Nerd, we find that hybrid mattresses, which combine both foam and coils, last longer than all-foam beds. We’d say this mattress should last seven to 10 years at least.

How Do the Policies Measure Up? 

Shipping & Unboxing

Handmade in the USA, the Helix Midnight ships for free anywhere in the U.S. It comes compressed in a box to your front door. The Queen size weighs between 90 and 100 pounds, so you may need to enlist the help of a friend to unbox it. Then once it’s opened, you unroll the mattress on its frame, and using scissors carefully unwrap the plastic. It took our Nerd team less than two minutes to unbox the Helix Midnight, which is a pretty average time. We also find that it can take bed-in-a-box mattresses up to 24 hours to fully inflate. You should know that some beds-in-box emit an “off-gassing” smell upon opening, but we found that to be at a minimum with the Helix Midnight.

Warranty

The Helix Midnight comes with a 10-year limited warranty. This warranty only extends to the original purchaser of the mattress, so you should keep a copy of your receipt as proof of purchase. The warranty applies to defects such as indentations of 1” or greater that are not associated with an indentation. But the warranty does not apply to preferences such as firmness level or temperature regulation ( i.e. “it sleeps too hot”). Note that you must return your mattress to Helix at your cost and provide the company with proof of the original date of purchase. You are also responsible for all shipping and transportation costs associated with replacing or repairing it. If the mattress is proven to have a manufacturing defect, Helix will reimburse you for shipping costs up to $100.

Trial Period & Returns

The Helix Midnight comes with a 100-night sleep trial that begins on the day it’s delivered. If you’re unhappy with your purchase for any reason, you can return it for a full refund within the 100-night trial period. However, mattresses require a 30-day break-in period before you can return it. Typically, the body takes about a month to adjust to a new bed. To return the mattress, you do not have to get it back in the box. Simply contact Helix, and they will have a donation partner pick up the mattress for you.

Comparing the Helix Mattress

Helix Midnight vs. DreamCloud Mattress

The construction of the Helix Midnight and the DreamCloud mattresses are quite similar: Both are foam over coils, only the Midnight is 12” thick and the DreamCloud is more plush at 15” thick. Both are also a medium firm feel.

Where their differences lie is in the feel: The Helix Midnight has a balanced foam feel, and the DreamCloud feels more like a traditional innerspring mattress with added bounce. So the former is best for side sleepers, and the latter is great for combination sleepers who change positions throughout the night. Regardless, both are high-quality mattresses that should last seven to 10 years.

DreamCloud Mattress

This hybrid mattress mixes memory foam and individually pocketed innerspring coils to deliver pressure-relieving support, especially for back and stomach sleepers. At a generous 15 inches tall with a quilted foam and cashmere cover, the DreamCloud exudes a plush, luxury hotel feel.

Helix Midnight vs. Nectar Mattress

The Helix Midnight is very different from the Nectar, as they have much different materials. The hybrid Helix incorporates coils at the base and foam on top, whereas the Nectar is a foam mattress. Thus, the Helix has a more responsive, balanced foam effect, and the Nectar features a more classic, slow-moving memory foam feel.

Thanks to its sturdy yet breathable innerspring coils, the Helix would be best for those who require more support and who sleep hot. Hybrid mattresses also tend to last longer than all-foam beds. The Nectar should appeal to those who prefer a classic, memory foam feel of being cradled by the mattress, as well as heavier side sleepers who need plenty of pressure relief. Still, both mattresses have the same firmness level, 6/10, which is a medium-firm level, and they are comparable in price.

Nectar

The Nectar is an affordable quality mattress with an excellent trial period. It suits all types of sleepers, couples and people who love sleeping on memory foam.

Helix Midnight vs. Purple Mattress

The best indication of how a mattress feels is its construction, and the materials in the Helix Midnight and the Purple are completely different. While the Midnight is a hybrid bed with foam over coils, the Purple features its own hyper-elastic polymer grid with a unique feel (one tester remarked it’s like lying on a bed of squishy jelly beans).

Still, the mattresses have a similar firmness level (medium firm) and while both are quite durable, the Purple’s proprietary materials may last longer. We’d recommend the Helix for lightweight to average-weight side sleepers who prefer a more classic mattress, and the Purple for heavier side sleepers, hot sleepers, and those who embrace new, innovative materials.

Purple Mattress

The Purple mattress is perfect for value-seekers who prefer a temperature-neutral mattress with a floating feel, thanks to its special 2" Purple Grid and dual-layered comfort foam.

Helix Midnight Mattress FAQs

How long will it take for your mattress to arrive?

Helix mattresses are all made-to-order—actually, handmade—in the USA. They are typically produced within one to two weeks’ time, plus shipping.

Is the packaging recyclable?

Yes, all of the packaging materials are recyclable, including the box. In fact, Helix challenges you to exercise your creativity and show off your upcycling skills. Customers have transformed their packaging into rocket ships, bedside tables, pet mansions and more. The company requests that you take pictures of your piece de resistance and tag them in your photos. (@helixsleep #napcity)

Are the materials in the Helix mattress harmful to people or the environment?

No, your Helix mattress is made of materials that are 100 percent produced in the USA and hand-assembled in their domestic factory. All materials are OEKO-TEX Standard 100 certified free from harmful chemicals. According to the OEKO-TEX website, “if a textile article carries the Standard 100 label, you can be certain that every component of this article, i.e. every thread, button and other accessories, has been tested for harmful substances and that the article therefore is harmless for human health.”

What’s the Bottom Line?

The Helix Midnight mattress proves to be an excellent bed for lightweight to average-weight back and side sleepers. But we find that strict stomach sleepers might require a higher firmness level—such as the Twilight and the Dawn models—and heavyweight sleepers should try the Helix Plus. (In fact, there are more than a half dozen Helix mattresses to choose from.) While the Helix Midnight is not as responsive and might not appeal to combination sleepers, hot sleepers will enjoy the breathable cover and the airflow, thanks to the individually wrapped coils. And couples will appreciate the excellent edge support and motion isolation.

However, all of these benefits come with a higher price tag that might not be as appealing for budget shoppers. Memory foam purists might also not enjoy the coils included in the hybrid construction. For 2” more of foam layers, a zoned lumbar support system and a premium pillow top, check out the upscale version, the Helix Midnight Luxe.
