Helix Midnight Mattress Review

The Helix Midnight is a hybrid mattress that features plush memory foam over pocketed coils for a one-two punch of pressure relief and support. It also happens to be the most popular bed in the Helix line… but is it the one for you?

To find out, check out my full review of the Helix Midnight mattress below. I’m going to review both the standard and luxe Helix Midnight models. I’ll go over these beds’ construction, suss out their feels, and test them out for important feel factors like firmness, pressure relief, and motion transfer. Then, you’ll know with absolute certainty whether or not the Helix Midnight or Helix Midnight Luxe is right for your slumber needs.

Is the Helix Midnight a Good Mattress for You?

The Helix Midnight is one of Helix’s six hybrid bed-in-a-box mattresses. It comes in a standard version and a luxe version. The luxe version has additional features like a pillow top and zoned support. The main difference between Helix’s six mattresses is their firmness level — the Midnight ranks right in the middle and is a true medium-firm mattress. But is it right for your specific sleep needs? Depending on your body weight, preferred sleeping position, and whether or not you sleep with a partner or pet, the Helix Midnight may or may not work for you. Take a look at some of my recommendations below.

Who I recommend the Helix Midnight mattress for

  • I think the Midnight is a great choice for couples. It has low motion transfer, which means you’re unlikely to be disturbed by your partner’s movements, and it has great edge support, so you can use the whole mattress.
  • Combination sleepers are likely to be happy with this bouncy mattress. They won’t feel “stuck” in bed and switching positions should feel easy.
  • I like this bed for both back sleepers and side sleepers. It has a medium-firm feel that both of these sleepers should be happy with.

Who I don’t recommend the Helix Midnight mattress for 

  • I wouldn’t recommend this mattress to heavier sleepers (those over 250 lbs.). I don’t think these individuals will get the support they need from the Midnight. Luckily, Helix has a mattress specifically designed for larger body types, the Helix Plus mattress
  • I think stomach sleepers will find this mattress too soft for their needs. I’d steer them to the firmer Helix Dawn or one of our best mattresses for stomach sleepers.

How Firm is the Helix Midnight Mattress?

Now that we know what’s inside the mattress, let’s discuss how it actually feels when you’re using it.

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. Just FYI, I’m around 5’10” and 190 lbs.

The Helix Midnight has a medium firm feel that many people will enjoy

After lying on the mattress for a while, I gave the Helix Midnight a 6 out of 10 rating on the mattress firmness scale (with 1 being the softest and 10 being the firmest), making it medium-firm. I would recommend it for side or back sleepers, because it’s supportive without putting pressure on your joints. The model also has a nice bouncy feel, thanks to its hybrid construction. That means it’s easy to roll around on, so you shouldn’t have trouble changing positions at night.

The Midnight Luxe has an extra pillow top layer and zoned support. It feels a touch firmer than the standard Midnight, and I gave it a 6.5 out of 10 rating on the firmness scale. This means it’s a true medium-firm mattress. I’d especially recommend it to those who suffer from back pain, since zoned support helps promote a healthy, straight spinal alignment.

Helix Midnight Mattress Performance

After assessing how a mattress feels, I like to run a couple of specific tests on the models I review, so I can offer a bit more information about how they perform and what kind of sleeper they suit best. Read on below to see how the Midnight stacks up.

Testing the Helix Midnight Mattress in Different Sleeping Positions

As I mentioned above, a mattress will feel different to you depending on your preferred sleeping position and body type. Take a look below to see how this bed performs for different sleepers.

Is the Helix Midnight a Good Mattress for Light Sleepers (Under 130 lbs)?

  • Light Back Sleepers – These sleepers should be happy on the Midnight or Midnight Luxe, which will offer some nice contouring at the lower back.
  • Light Side Sleepers – Lighter side sleepers should stick with the standard Midnight mattress, which is a bit softer than the Midnight Luxe and should offer enough cushioning around their pressure points.
  • Light Stomach Sleepers – Light stomach sleepers could be happy on the Midnight Luxe if they only spend part of the night on their stomachs. But in general, I’d recommend these sleepers opt for a firmer mattress.

Is the Helix Midnight a Good Mattress for Average Weight Sleepers (130 – 250 lbs)?

  • Average Weight Back Sleepers – These folks should be happy on either Midnight model. Both will offer a nice balance of pressure relief and support. If you struggle with back pain, I’d recommend opting for the Midnight Luxe, which offers a bit more lumbar support than the standard model.
  • Average Weight Side Sleepers – The standard Midnight is a nice choice for side sleepers. It won’t put too much pressure on your shoulders, hips, or other sensitive joints. The Midnight Luxe could also be a good fit for these sleepers.
  • Average Weight Stomach Sleepers – I wouldn’t recommend either bed for strict stomach sleepers, who will need a firmer mattress to offer proper spinal support.

Is the Helix Midnight a Good Mattress for Heavy Sleepers (over 250 lbs)?

  • Heavy Back Sleepers – Heavy back sleepers could like the Midnight Luxe. It’s zoned support structure offers a lot of lift around the hips, which should support these folks well.
  • Heavy Side Sleepers – Similarly, the Midnight Luxe could work for heavy side sleepers. It should offer them some nice pressure relief, while helping them maintain a healthy spinal alignment.
  • Heavy Stomach Sleepers – Neither Midnight mattress will be supportive enough for heavy stomach sleepers. One of our best mattresses for stomach sleepers could be a better fit.

Helix Midnight Mattress Pain Relief Performance

Pain relief is an important factor to consider when choosing a bed. It’s also closely tied to pressure relief, which is a measure of how well a bed cushions sensitive pressure points throughout the body.

To see how a mattress relieves pressure, I use a pressure map, which is basically a special mat you roll on top of a mattress and lie down on to see how much pressure is exerted on different parts of the body. It produces a color-coded chart showing pressure areas on a gradient ranging from low pressure (blue) to high pressure (red). Take a look at the standard Helix Midnight’s pressure map results below.

I was impressed with the Helix Midnight’s pressure relief in multiple positions.

Back Pain – Based on these results, the Midnight does a great job relieving pressure at the lower back! But, I’d opt for the Midnight Luxe if you struggle with back pain, because it does a better job of combining support with pressure relief in this area.

Shoulder Pain Looking at the map above, it looks like the standard Midnight could be a great option for sleepers who deal with shoulder pain. It should offer enough cushion to prevent stiffness in that area.

Hip Pain – Similarly, sleepers with hip pain could benefit from the medium-soft feel of the Helix Midnight mattress. It should do a nice job cushioning the sensitive hip joints, especially for side sleepers.

Helix Midnight Mattress Performance for Couples

The best mattress for couples normally combines responsiveness, motion isolation, cooling features, and edge support. Read on below to learn about each of those terms, and to see how the Helix Midnight performs in those categories.

Motion Transfer

Motion transfer is a measure of how much motion a mattress absorbs. It tells you how disturbed you’ll feel by someone tossing and turning on the opposite side of your bed, which is why couples often find it important.

To test motion transfer, I placed a seismometer on one side of the mattress, then dropped a 10 lb. steel ball from three different heights on the other side. The seismometer measured the levels of disturbance.

Motion transfer test results for the Helix Midnight

You can see the standard Midnight’s results above. The standard Midnight does a great job isolating motion, which means you shouldn’t feel overly disturbed by a restless partner on this bed. The Midnight Luxe didn’t isolate motion as well, but still did an okay job.

Sex

The best mattress for sex is normally responsive and easy to move around on. Since the Midnight Luxe is a little firmer than the standard Midnight, it’s a better option for sex. But, both beds should be fairly easy to move around on during sex.

Cooling

Since two bodies create more body heat than one, cooling properties are great features for couples mattresses. The Midnight and Midnight Luxe both sleep cool thanks to their breathable hybrid constructions. But the Midnight Luxe’s Tencel cover means it sleeps a little cooler than the standard model.

Edge Support

Another consideration when you’re buying a mattress to share is edge support. Can you spread out on your mattress and still feel supported, or do you and your partner need to cram together in the center of the bed? The Helix Midnight models both offer great edge support. I felt secure at the edge of both beds.

What is the Helix Midnight Made Of?

So, what’s actually inside this bed? The Helix Midnight mattress is one of my picks for the best hybrid mattresses, meaning it contains both memory foam and pocketed coils (some other models just have one or the other!). Let’s dive in to learn a little bit more about each specific layer.

Standard Helix

Cover – The cover is made from a light, stretchy material that helps promote airflow to keep you cool at night. It’s super soft to the touch and comes in a nice heather grey color.

Comfort Layer – Next up is a top layer of memory plus foam. This blended foam should help relieve pressure at the joints and offer a nice contouring feel when you’re lying on the mattress. Memory foam can sometimes make you feel like you are “stuck” in the bed, but since the memory foam layer isn’t too thick in this model, I don’t anticipate many people having that problem.

Transition Layer – A second layer of high-grade polyfoam foam separates the memory foam from the pocketed coils below. This foam layer provides a cushioning feel and more ergonomic support for your body, and adds some support underneath the memory foam layer.

Support Layer – The support layer consists of individually wrapped coils. These help to support your body, and offer a bouncy feeling to the bed so you don’t feel “stuck” in the mattress or struggle to roll over, get in and out of bed, or move positions.

Base Layer – Finally, the base of the mattress is made with a final layer of DuraDense foam for maximum support, ensuring the mattress doesn’t sag.

Helix Midnight Luxe

Cover – The Luxe’s breathable cover is made of Tencel, a natural fiber made from Eucalyptus. It has a soft and luxurious feel and helps with temperature regulation.

Pillow Top – Next up is a pillow top layer quilted with gel foam to provide some initial pressure relief and cushioning.

Comfort Layer – The Helix Luxe has a two-layer comfort layer. First up is a layer of memory plus foam, just like in the standard Helix. Then there’s a layer of gel visco foam, which adds some extra contouring and pressure relief.

Transition Layer – This layer is made from high-grade polyfoam, just like in the standard version. It provides ergonomic support and prevents the sleeper from sinking all the way down to the coils.

Support Layer – Next up is a layer of 1,000+ individually wrapped coils. These coils have zoned support, which means they’re softer at the shoulders for added pressure relief, and firmer at the hips to help promote a neutral spinal alignment. Zoned support is great for sleepers with back pain, as it helps keep the spine nice and straight (the key to preventing/soothing back pain).

Base Layer – Lastly is a layer of DuraDense foam, just like in the standard model. This foam adds a bit of support and durability to the mattress.

Helix Midnight Mattress Unboxing and Off-Gassing

Like all bed-in-a-box mattresses, both Helix Midnight mattresses will undergo a 24-72 hour off-gassing and decompression period after they’re opened. Personally, I found these beds to have a stronger-than-average off-gassing odor. But, as long as you leave your new bed in a ventilated room, this smell is nothing to worry about and should dissipate after one or two days. I’ll also note that if you choose to buy the Helix Midnight Luxe, you might want to have a friend help you unbox it, as it is a fairly heavy mattress.

My Final Thoughts about the Helix Midnight Mattress

Now that we’ve gone through what the Helix Midnight is made of, how it feels, and how it performs in my tests, we get to the ultimate question: Is it a good selection for you? Here are some pros and cons you should consider if you’re thinking about purchasing it.

My favorite things about the Helix Midnight mattress

I love that the Helix Midnight offers great edge support — you can use the whole bed! It also has great motion isolation, which makes it a nice option for couples. I also really like this bed for combination sleepers. 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.

My Helix Midnight mattress complaints

I don’t think this mattress is firm enough for stomach sleepers. These sleepers should opt for one of Helix’s firmer models or another firm bed. I would also say that this bed is not the best pick if you have a heavier body weight. Instead, look at some of the firmer models from the Helix Luxe line or the Helix Plus —the Plus mattress is designed specifically for plus-sized individuals!
