Firmness & Feel

Helix Sleep offers over six different mattress models to cater to every type of sleeper’s needs.

Construction & Design

The construction of Helix mattresses will vary depending on whether you get the classic or luxe version of a mattress. Each standard mattress, whether it’s the Midnight, Dusk or any other, can upgrade to the luxe mattress, which offers two additional inches and two additional layers. The difference between the Luxe and standard versions are the two extra layers that the luxe version has: the pillow top topper and the targeted lumbar support. 

However, all Helix mattresses come with the same base of construction which include these five Helix mattress layers:

Layers Description
Cooling cover Choose between either the TENCEL cover or the GlacioTex Cooling Cover. Each cover will help cool the mattress with breathable technology and is cool to the touch.

Is Helix Midnight a good mattress?

Based on Helix Mattress reviews, the Helix Midnight mattress is known for its excellent pressure relief, cooling, and motion isolation. Here are some of the best features that customers have highlighted:

Helix Mattress Back Pain

The Helix Midnight mattress was designed to give you excellent support, helping to combat upper and lower back pain. It's especially helpful for side sleepers because it is specifically designed to support your shoulders and hips which is why many reviewers have stated it being the best Helix mattress for back pain. 

If you’re looking for even more targeted relief for back pain, consider upgrading to the Helix Midnight Luxe which includes “zoned lumbar support coils''. This zoning technology provides a softer feel under your shoulders and firmer feel under your hips which will help support your body and align your spine.

cooling mattress icon

Helix Mattress Cooling

Helix cooling mattress is one of the coolest on the hybrid market, that’s especially impressive considering its use of foam in the construction. That’s in thanks to its pocketed coil system which allows airflow to move throughout the center of the mattress. 

If you’re looking for even more cooling, you also have the option of two hypoallergenic cooling covers: a breathable, moisture-wicking TENCEL™ cover or you can upgrade to the GlacioTex™ Cooling Cover which is made from a high thermal conductive material that dissipates heat quickly.

Helix Mattress Motion Isolation

According to Helix reviews, couples who are often woken up by their partner's tossing and turning have praised the Helix Midnight's motion isolation, saying that they noticed a significant decrease in movement felt. 

Typically you would find that all-foam mattresses perform the best in this category but in the Helix Midnight the pocketed coil system works well in isolating motion. Which means if you share your bed with a partner who moves around a lot during the night, you are less likely to be disturbed by their movements which is why the Helix Midnight ranks highly in best mattresses for couples.

Helix Mattress Edge Support

The Helix Midnight performs very well for edge support. The reinforced edge support comes from the 1,000 individually wrapped coils in the center of the mattress. The standard model is reinforced around two sides of the bed, while the Luxe model has reinforced edges around all four sides - both do a great job of making the bed feel sturdy and larger than it is. Couples who share a bed will find they can spread out, and if you’re a sleeper who sleeps near the edge you won’t have the fear of tumbling over.

Helix Mattress Sex

The best mattresses for sex have a few key factors. They’re responsive and the right amount of bouncy, they have solid edge support for optimal movement and lastly they’re cooling. For all those reasons, the Helix Midnight is a great choice for sex. The pocketed coils are responsive and provide the mattress with a bouncy feel.

Helix Mattress Off Gassing

Helix Sleep ships their mattresses in a box which means when unpacked your Helix mattress will begin to expand and release an odor called “off-gassing”. This is typical for mattresses that are constructed with foam. The odor will typically dissipate within 24-48 hours. 


Helix Sleep Quiz

Helix mattresses can be customized to suit different sleep preferences. Sleepers can choose based on sleep positions, firmness, weight and more. Helix Sleep makes this even easier by providing the Helix Sleep quiz which can help you determine the best mattress for your specific needs. According to Helix reviews, people find this feature impressive and accurate.

Sleeping Positions

Helix Sleep pays special attention to where to place the support in the mattress depending on what kind of side sleeper you are. That’s what makes Helix unique is its different mattress options that you can choose based on firmness which allows you to tailor your mattress to your unique needs. 

side sleeper icon
Helix Mattress Side Sleeper

Side sleepers need support near their pressure points. To accommodate this sleeping position, the Midnight mattress has middle layers that contour your body. These layers will help eliminate pain and relieve pressure on the shoulders and hips. They require specific support that the Sunset, Midnight, and Twilight mattresses all cater to. Side sleepers above 130 lbs will find the medium firm feel the perfect balance of catering to those pressure points, while Helix side sleepers who weigh less than 130 lbs might enjoy a softer Helix mattress.

back sleeper icon
Helix Mattress Back Sleeper

The Helix Midnight mattress can be a good choice for back sleepers. In Helix mattress reviews, back sleepers note that it provides enough support and pressure relief to help align the spine. If you are suffering from back pain, you might consider upgrading to the Luxe model which has lumbar zone technology specifically targeting pressure relief in your back. 

The Helix Midnight’s medium firm feel is a solid choice for back sleepers who need more support on their hips and shoulders. Back sleepers of most sizes will find this is a great choice however if you weigh more than 230 lbs, consider the Plus version which specifically caters to Helix plus-sized sleepers. 

stomach sleeper icon
Helix Mattress Stomach Sleeper

If you are a stomach sleeper, it can depend on your weight if the Helix Midnight is a good choice for you. Helix stomach sleepers typically should opt for one of the firmer mattresses like Helix Dusk or Dawn so that there is less "sinkage" into the mattress. However some Helix Midnight reviews state that the medium-firm feeling is more firm than soft and so it will be a good choice for you after all. If you weigh more than 230 lbs, opt for a firmer mattress since stomach sleepers need to be supported in the hip area to remove strain from the lower back and keep the spine aligned.
