This bed has great motion isolation, so you shouldn’t feel your partner tossing and turning at night.
Pros of the Helix Midnight
Back sleepers should get some cushioning in the lumbar region, and the coils will help keep their spines neutrally aligned.
Side sleepers should experience nice pressure relief and contouring at their shoulders and hips. For extra pressure relief, we recommend the Helix Midnight Luxe, the standard Helix Midnight’s luxury version.
The Helix Midnight has low motion transfer, which means partners aren’t likely to feel each other moving around at night.
The Midnight is a responsive mattress, so it’s ideal for combination sleepers.
Cons of the Helix Midnight
Not supportive enough for people over 250 pounds. For them, we recommend one of the best mattresses for heavy people.

The Helix Midnight is amongst Helix’s line of six standard mattresses. It’s known for its more balanced feel, allowing it to accommodate a wide range of sleepers. We also recommend it for couples, as it scored well on our motion isolation, responsiveness, edge support, and cooling tests. For a plusher and more cooling version of this mattress, see the Helix Midnight Luxe. Learn more in our video review.

What our tester says:

“I would recommend this mattress for side or back sleepers because it’s supportive, without putting pressure on your joints.” – Nichole Mondshein, lead reviewer and staff writer

What is the Helix Midnight Made Of?

The Helix Midnight is 12 inches tall with four layers. Let’s dive in to learn a little bit more about each specific layer.

Cover
The Helix Midnight Breathe Knit cover is soft, light, and stretchy to promote airflow and help keep you cool. You can also choose a GlacioTex Cooling cover for an additional cost if you sleep extra hot.
Comfort Layer
The comfort layer contains two layers of foam. The first layer is made from blended Memory Plus Foam that cradles sensitive pressure points, so sleepers should find some pain relief here. The second later of Helix Response foam has a medium feel that offers additional body contouring and support.
Transition Layer
Made from high-grade poly foam, this transitional Helix Response Foam adds a bit more supportive cushioning and ergonomic comfort.
Support Layer
The support layer is made from individually wrapped coils that add support and some bounce to facilitate movement on the bed.
Base Layer
A final layer of DuraDense foam completes the mattress for optimized support and works to prevent the mattress from sagging.

Helix Midnight Mattress Firmness 

Before we get into this, a quick reminder — mattress firmness is not an objective measure. Your weight, sleep position, and personal preferences will inform how hard or soft you find any given model. That said, we try to give you a balanced firmness score by having several colleagues try out the Helix Midnight. They give their rating and we averaged the scores together.

Helix Midnight Firmness 6.5

After lying on the mattress for a while and tallying everyone else’s scores, the Helix Midnight scored a 6.5 out of 10 rating on our mattress firmness scale (with 1 being the softest and 10 being the firmest), making it a medium-firm bed. In fact, 6.5 is the industry standard for medium firmness. We would recommend this mattress for all three sleeping positions (back sleeping, side sleeping, and stomach sleeping) because it’s supportive, without putting pressure on your joints. This model also has a nice, bouncy feel, thanks to its hybrid construction. That means it’s easy to roll around on, so combination sleepers shouldn’t have trouble changing positions during the night.

Our favorite things about the Helix Midnight Mattress

Great Edge support

When you’re buying a mattress to share, an important consideration is edge support. Can you spread out on your mattress and still feel supported? The Midnight will make you feel secure using the whole bed.

Great for Couples

The Midnight has great motion isolation, which means you’re unlikely to be disturbed by your partner’s movements. The mattress is bouncy, making it easy for you to roll over or switch positions at night without worrying that you’ll get “stuck” in the bed.

Pressure Relief Performance

We tested this mattress using a pressure map.Based on the results, the Midnight does a great job relieving pressure at the lower back, cushioning sensitive hip joints, and preventing shoulder stiffness.

Customer Feedback

“I love my new bed! This mattress is so comfortable. The first few nights I used it, I immediately noticed that I slept much better (and longer!).”

-Rebecca H.
Verified Buyer

“I have had my mattress for about a month now and have to say it is way more comfortable than the $4000 mattress I had before. I sleep more sound and actually feel great in the morning.”

-Joy K.
Verified Buyer

“This mattress is equal to or better than any other I have slept on. I’m convinced traditional mattress distribution and pricing are a racket. Helix is a superior value proposition and a quality product.”

-Michael M.
Verified Buyer

Frequently Asked Questions

Who is the Helix not Recommended for?

The Helix is not recommended for people with a heavier body weight. Heavier people should look at the firmer models from the Helix Luxe line or the Helix Plus.

Does the Helix Midnight have an off-gassing period?

The Helix Midnight will ship to your door compressed in a box. You will need to wait after unboxing the Helix for gasses to be released as the foam decompresses. However, all smell should dissipate in 24-72 hours.

How does the trial period work?

If you’re unsatisfied with your new mattress, you can return it after the 30-day “break in” period and before the end of the 100-night trial period for a full refund.
