Who Is the Helix Midnight Best For?

The Helix Midnight is Helix Sleep’s most popular mattress. It combines foam and coil layers to provide a medium-firm feel that caters to the needs of various sleepers. Helix Sleep reviews particularly note the Midnight’s excellent pressure relief for side sleepers because of its plush top layer. 

It is also suitable for back and stomach sleepers who prefer a firmer surface to keep their spines aligned properly. The Midnight has excellent motion isolation and edge support, which makes it a fantastic option for couples. 

Ideal for: 

  • Side and back sleepers 

  • Couples or people who sleep with pets

  • Couples with different sleeping preferences

  • People seeking a luxury bed

  • Sleepers who sleep near the edge of the bed

Firmness & Feel

Helix Sleep offers over six different mattress models to suit every type of sleeper. The Helix Midnight is their most popular model thanks to its medium-firmness feel, which is popular with couples with different firmness preferences. 

Most reviewers of Helix Midnight claim that it offers both support and comfort and provides pressure point relief. That’s because it is designed to contour to the body’s shape to support spinal alignment while providing cushioning for the sleepers’ shoulders and hips. 

Each Helix mattress model can be upgraded to the Luxe version, which offers more support, six layers, and an increased height profile of 13.5”. Unlike the Classic version, the Luxe has a quilted pillow topper for added comfort and a zone specifically made to help with lumbar support.
The Helix Midnight Luxe firmness does not change when upgrading to the Luxe version, as it still falls around the medium-firm range.

Construction & Design

The construction of Helix mattresses depends on whether you get the Classic or Luxe version. Standard (or Classic) mattresses, whether the Midnight, Dusk or any other option, can be upgraded to the Luxe version, which offers two additional inches and two additional layers. 

The difference between the Luxe and Standard versions is the two extra layers of the Luxe version: the pillow top topper and the targeted lumbar support. 

That said, all Helix mattresses come with the same base of construction, which includes these five Helix mattress layers:

Layers Description
Cooling cover Choose between either the TENCEL cover or the GlacioTex Cooling Cover. Each cover cools the mattress with its breathable technology and is cool to the touch. 
Comfort layers These two layers are made of plush memory foam and high-grade polyfoam with a medium-firm feel to provide cushioning and support.
Transition layer This layer of high-grade polyfoam provides ergonomic support and cushioning. 
Body shape layer This layer has up to 1,000 individually wrapped coils that cradle your body while limiting motion transfer. The coils are reinforced to provide optimal edge support. 
DuraDense Foam The bottom foam layer provides base support to the entire mattress.

Is Helix Midnight a Good Mattress?

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

person on mattress icon

Helix Mattress Back Pain

The Helix Midnight mattress was designed to provide excellent support and combat upper and lower back pain. It's beneficial to side sleepers because it is specifically designed to support your shoulders and hips. This is one of the main reasons many reviewers claim it is 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 a firmer feel under your hips to help support your body and align your spine.

Helix Mattress Cooling

The Helix Midnight is one of the best cooling mattresses in the hybrid market. That’s impressive, considering the use of foam in its construction. Its high cooling prowess is due to its pocketed coil system, which allows maximum airflow throughout the center of the mattress. 

If you’re looking for even more cooling, you can choose between two hypoallergenic cooling covers: the breathable, moisture-wicking TENCEL™ cover or the GlacioTex™ Cooling Cover, which is made from a highly thermally conductive material that dissipates heat quickly.

Helix Mattress Motion Isolation

According to most Helix reviews, couples who are often woken up by their partner's tossing and turning while sleeping praise Helix Midnight's motion isolation, saying that they notice a significant decrease in their movement. 

Although all-foam mattresses perform well in this category, the Helix Midnight’s pocketed coil system does an excellent job of isolating motion. So, if you share your bed with a partner who moves around a lot while sleeping, you are less likely to be disturbed by their movements. This explains why most reviews claim that the Helix Midnight ranks highly in the best mattresses for couples category.

Helix Mattress Edge Support

The Helix Midnight offers excellent 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 make 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 to fear tumbling over.

Helix Mattress Sex

The best mattresses for sex have a few key factors. They’re responsive and have the right bounce. They also have solid edge support for optimal movement and great cooling features. The Helix Midnight has all these features, which make it a great mattress for sex. The pocketed coils are responsive and provide the mattress with a bouncy feel.

Helix Mattress Off Gassing

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

Helix Sleep Quiz

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

Sleeping Positions

Helix Sleep pays special attention to where the support is placed in the mattress. They do this based on the kind of side sleeper their customers are. One of the things that makes Helix unique is that it offers different mattress options, from which you can choose based on mattress firmness.

side sleeper icon
Helix Mattress Side Sleeper

Side sleepers need support near their bodies’ pressure points. The Midnight mattress has middle layers that contour your body to accommodate this sleeping position. These layers help eliminate pain and relieve pressure on the shoulders and hips. 

Side sleepers require specific support, and the Sunset, Midnight, and Twilight mattresses offer this. Side sleepers above 130 lbs will find that the medium firm option provides the perfect balance to cater to their bodies’ pressure points. Conversely, Helix side sleepers who weigh less than 130 lbs might prefer a softer Helix mattress.

back sleeper icon
Helix Mattress Back Sleeper

The Helix Midnight mattress might be a good choice for back sleepers. In many Helix mattress reviews, back sleepers noted that the Midnight provided enough support and pressure relief to help align the spine. Back sleepers who suffer from back pain might consider upgrading to the Luxe model, which has lumbar zone technology and specifically offers pressure relief to the back. 

The Helix Midnight’s medium-firm feel is a solid choice for back sleepers of different sizes who need more support for their hips and shoulders. However, if you weigh more than 230 lbs, you might want to consider the Plus version, which specifically caters to Helix plus-sized sleepers.

stomach sleeper icon
Helix Mattress Stomach Sleeper

For stomach sleepers, the suitability of the Helix Midnight depends on their weight. Helix stomach sleepers should opt for one of the firmer mattresses like Helix Dusk or Dawn because there is less "sinkage" into the mattress. 

However, some Helix Midnight reviews state that the medium-firm option is firmer than the soft option and might be a good mattress choice. If you weigh more than 230 lbs, you should opt for a firmer mattress because stomach sleepers need to be supported in the hip area to remove strain from the lower back and keep the spine aligned.
