Cover
The layers of the Helix Midnight Luxe are wrapped in a thick and quilted cover. The mattress we tested included a cover made with a Tencel blend. Optional is a cover with higher-density fibers that give it a coolness to the touch.
Comfort & Feel
There are three aspects that make up our assessment of comfort and feel. We call these "preference-based characteristics" because no rating here is better or worse – rather, the attributes that are most desirable to you will be determined solely by your personal preferences. We apply the same classification standards to each mattress so you can more easily compare apples to apples.
Softness ( what’s this )
Keep in mind that what mattress companies call “firm” or “soft” is a purely a preference. All mattresses should be supportive and promote healthy spinal alignment. Whether a mattress is fluffy and squishy (what mattress companies call soft or plush), or less so (what companies call firm), is purely down to your personal needs and preferences.
We found the Helix Midnight to be a Medium Soft on our scale; in fact it was very close to a Soft on our ratings scale.

| Softness Level (1=Least Soft, 9=Most Soft) |
6 | Medium Soft |
Cushioning Depth ( what’s this )
This refers to how deeply you sink into the mattress or feel cradled or hugged, versus a feeling of floating on top of the bed.
While the Helix Midnight Luxe has memory foam, the foam isn't very squishy, and springs back into shape quickly. However, those foams are pretty soft, and you sink more into the mattress than average. However, it's not a very conforming mattress; that is, it doesn't closely hug your every curve. So even while it's a soft mattress, you don't feel swallowed up by foam.
| Cushioning Depth (1=Shallowest, 9=Deepest) |
6 | Slightly deeper than average |
Responsiveness ( what’s this )
Responsiveness refers to how quickly a mattress recovers its shape after being compressed. When you press your hand into the mattress, for instance, then remove it, does it take several seconds for the mattress to return to flat, or does it recover immediately?
While the Helix Midnight Luxe does contain memory foam, there isn't much of that melting into the bed feeling that memory foam is known for.
We also tested the bed for bounce. Unsurprisingly, since most of this bed is made of steel springs, we did find some bounce. The foam on top of the springs dampens quite a bit of the expected bounciness.

5 | Average |

Back Support & Pressure Relief
The two things that you should always be sure to get from your mattress are spinal alignment (commonly thought of as "back support") and pressure relief. Unfortunately, no mattress will deliver these two things equally well for all sleepers. In particular, spinal alignment and pressure relief capabilities will vary across sleepers with different weights, body shapes, and sleep positions. To help you determine how this mattress will perform for you, we break down our spinal alignment and pressure relief assessments by sleeper type.
In our evaluations, we thought the Helix Midnight Luxe would especially suit combination sleepers that are average weight of lighter. Heavier people might instead want to look at Helix's firmer mattresses, including the Helix Plus.
Spinal Alignment
The key to good back support is maintaining proper spinal alignment while you sleep. This means that the mattress should hold your spine in roughly the same position it's in when you're standing. The ability of a given mattress to do this will generally depend on your weight, sleep position, and body shape.
Here is how we break down the spinal alignment of the Helix Midnight mattress:
| Weight | Range | Back Sleepers | Side Sleepers | Stomach Sleepers |
| Lighter | <150 lb | 9 | 9 | 8 |
| Average | 150 to 200 lb | 9 | 9 | 7 |
| Above Average | 200 to 250 lb | 8 | 8 | 6 |
| Heavier | >250 lb | 7 | 7 | 5 |
Back Sleepers:
Our tester felt that sleepers of about his weight (200 lbs.) or lighter would be well suited for the Helix Midnight Luxe. Because the mattress is so soft, we thought it less suitable for heavier back sleepers, whose hips might sink through the top foams and end up resting mainly on the coil unit. Rather, heavier back sleepers might check out one of Helix's firmer mattresses.
Side Sleepers:
Along the same lines, we thought average-to-lighter side sleepers would experience good spinal alignment on the Helix Midnight Luxe, but heavier people might sink too much in the hip area, through the spine out of alignment.
Stomach Sleepers:
Very light stomach sleepers should be okay on the Helix Midnight, but it's too soft for other stomach sleepers. Once your hips sink too much, you over-arch your back and that's a recipe for back pain. Rather, stomach sleepers might have a look at Helix's firmer mattresses.
Pressure Relief
When a mattress pushes back against your body with too much force in a concentrated area, the result can be pain, soreness, loss of circulation, excessive tossing, and other problems. In general, such "pressure points" are of greatest concern for side sleepers, since that's the position in which your body's weight is distributed over the smallest surface area. To find the right mattress for your needs, keep in mind that the pressure-relieving capabilities of any given mattress will vary depending on the sleeper. Factors like your weight and body shape (e.g., broader shoulders and/or hips) will determine how far you sink into the mattress, and the pressure relief offered by that mattress will vary widely at different depths.
Here's how we sized up the pressure relief of the Helix Midnight Luxe mattress:
| Weight | Range | Typical Curves | Extra Curvy |
| Lighter | <150 lb | 9 | 9 |
| Average | 150 to 200 lb | 9 | 8 |
| Above Average | 200 to 250 lb | 8 | 7 |
| Heavier | >250 lb | 7 | 6 |
As with spinal alignment, we thought pressure relief would be best for those of average or lighter weight. Heavier people might just sink though the foam layers and find themselves resting on the coil unit, which won't provide much (if any) pressure relief.
Other Features
Beyond the preference-based characteristics of comfort and feel, and the body matching for spinal alignment and pressure relief, a mattress will have a number of other attributes that can make it a better or worse choice for you. We call these "priority-based characteristics" because they are areas in which a mattress can be better or worse, but that will have differing amounts of importance to each sleeper. So, determining how much importance to give to these features will be entirely a matter of your own personal priorities. As always, we apply the same ratings standards to each mattress so you can more easily compare apples to apples.
Motion Isolation ( what’s this )
If you are easily disturbed by a partner's movements in bed, or perhaps you and your partner go to bed and get up at different times, then motion isolation may be a priority for you. Innerspring mattresses in general are not the best choice, but the springs are pocketed in the Helix Midnight Luxel (as they are in many modern mattresses), so the movement of each spring is isolated.
We test for motion isolation by positioning a bowling pin upright on one side of the bed, then dropping a bowling ball on the other side and observing what happens with the pin. Next, our tester drops his whole weight on the bed. In both tests, our pin wobbled, but never fell.

Temperature ( what’s this )
For most people, we do not think the Helix Midnight Luxe mattress will feel hot, not so much because it has specific cooling features, but because it's physical characteristics have advantages.
Spring and coil mattresses in general will naturally provide greater air flow than foam, allowing for lots of air flow. The Midnight has edge-to-edge coils, so there's no edge foam that could potentially inhibit airflow.
While you do sink into the mattress a little more than average, it's not a super conforming mattress, and that allows for more airflow.
If overheating in bed is an issue for you, we think the Helix Midnight Luxe would be a very good choice.

Edge Support ( what’s this )
Edge support is important if you like to sit on the side of the bed, or if you tend to sleep along the edge. We found the Helix Midnight to feel very stable. Note, however, that the edge support coils run only on the long sides, not at the head or foot of the bed.
Our tester especially felt stable while laying right on the edge. Overall, we think the Helix Midnight Luxe is a very good choice for those who find themselves laying right on the edge.

8 /10 | Very good |
Ease of Repositioning ( what’s this )
If you tend to move and change positions a lot over the course of a night, ease of repositioning will be a priority for you. The Helix Midnight Luxe mattress posed no hindrance to movement. Our tester had no trouble at all moving around or rolling into another position, despite the soft materials at the top.

Green Features ( what’s this )
For mattress shoppers concerned with the use of natural materials, sustainable manufacturing practices or the like, we offer our subjective evaluation of any efforts taken by the company to make the mattress more green, healthy, or safe.
Helix makes no claims that this mattress is natural, but at least the foams utilized are certified to the CertiPUR-US standard, which verifies that a material has low VOC off-gassing as well as a lack of chemicals and other substances regulated by the CPSC. Obtaining this certification is pretty much standard for mainstream mattress brands today.
On the plus side, steel coils are not known for issues with off-gassing, and at least theoretically, they are recyclable, which could reduce landfill waste when you eventually dispose of the bed.
The cover has furthermore been certified to the OEKO-Tex standard, which means that all materials used have been tested for more than 100 harmful substances including formaldehyde, lead, and petrochemicals and is deemed safe. That's an extra certification class that's far less common, and is a reassuring bonus.

Adjustable Base Compatibility ( what’s this )
We tested the Helix mattress on our standard adjustable base, looking for whether using such a base could damage the mattress or create any issues like bunching or bulges.
The Helix Midnight Luxe mattress is made to be used on an adjustable base, and in our test, the mattress conformed well to the base in its fully articulated position. When our tester got out of the bed, the midsection did lift up a bit, but we expect that over time, the mattress would break in and relax.
We did notice that the quilt bunches up quite a bit when the head and foot are fully raised. However, it's a soft fabric, and we did not find it annoying.

Price, Value & Longevity
How Much Does a Helix Midnight Luxe Mattress Cost?
Prices shown are list prices. Remember that GoodBed keeps our site current with the best available discounts on online mattresses, many of which are exclusive discounts for our readers.
Note that Helix offers former and current members of the military a 15% discount (cannot be combined with other discounts). Students, teachers and first responders also get a 15% discount.
What Are You Getting?
The Helix Midnight Luxe is a 13.5" tall hybrid mattress with pocket springs and about 4 inches of premium comfort memory foam.
How Long Will the Helix Midnight Last?
We typically use foam density as an indicator of longevity; and we look for what we think could be a weak link in terms of materials and construction. In the case of the Helix Midnight, the top two memory foam layers are 2.5-lb. density foams. We would prefer to see a higher 4-lb or 5-lb. density. Still, the Midnight Luxe comes with a solid warranty that alleviates misgivings.
Overall Value
The Midnight Luxe is a fairly standard type of construction: memory foam on top of a pocket spring support unit. It's a tall mattress with a pillowtop, and we were very impressed with the quality of stitching and construction. But in terms of price, it has a lot of competition among online mattress brands. But the Midnight Luxe is right in the mix with those competing models in terms of price, so we do think it's a good value. Furthermore, Helix has some very good holiday sales, and we've seen discounts as high as $300 off.
