Helix offers a range of mattress options to accommodate nearly every sleeping position and comfort preference. To help you determine which Helix mattress is right for you, the company offers a helpful sleep quiz. After answering a few questions about your needs and preferences, Helix directs you towards a personalized recommendation.

Helix offers 6 standard mattress models: Sunset, Moonlight, Midnight, Dusk, Twilight, and Dawn. Each Helix mattress has a hybrid design, but differs when it comes to comfort layers, firmness, and overall support. For each model there is also a Luxe version, which adds zoned support, a pillow top, and a breathable Tencel cover. Additionally, Helix offers a Plus mattress designed specifically for those who are plus size or big and tall. Here we’ll break down Helix’s most popular model: the Helix Midnight mattress.

The Helix Midnight mattress is a medium firm hybrid model with a memory foam comfort system. It is specifically constructed with side sleepers in mind and offers ample pressure point relief. Pocketed coils minimize motion transfer while adding bounce and support to the mattress.

We’ll cover the pricing, firmness, and construction of the Helix Midnight mattress. We’ll also break down how it performs in key categories like edge support, motion isolation, and temperature regulation. Based on extensive testing and verified customer reviews, we’ll also include our recommendations based on sleeping position and body weight.

Helix Mattress Review: Our Verdict

One of the benefits of purchasing a Helix mattress is the personalized quiz that helps narrow down your choices. Since the company has so many different options to choose from, there is something for nearly everyone. The Helix Midnight mattress is a great choice for side and back sleepers as it relieves pressure points and contours to the shape of the body.

For couples, the Helix Midnight mattress has a medium firm feel that appeals to different preferences and needs. It is especially supportive for those who weigh less than 230 pounds. The hybrid design includes a support core of pocketed coils and a thick comfort system of high-density memory foam. The construction of the Midnight mattress ensures ample airflow throughout the mattress and prevents the feeling of sleeping hot. Budget shoppers will also appreciate that the Helix Midnight mattress is competitively priced.

If you know you’re looking for a soft, plush mattress, it might be worth considering the Moonlight and Sunset models from Helix instead. Those who know they prefer a firm mattress may find the Helix Twilight or Dawn mattresses are better suited for their preferences. And for shoppers who weigh more than 230 pounds, the Helix Plus is constructed with additional support.

Choose the Helix if…

  • You aren’t sure where to start with buying a mattress online and want a personalized recommendation
  • You sleep on your side
  • You’re part of a couple, and both of you are side or back sleepers
  • You weigh less than 230 pounds
  • You are looking for a hybrid mattress at a relatively affordable price point

Keep Shopping if…

  • You want a soft, plush mattress (take a look at the Helix Moonlight or Sunset models)
  • You want a firm mattress (consider the Helix Twilight or Dawn models)
  • You weigh more than 230 pounds (the Helix Plus will be a better fit)

How Much Is the Helix Mattress?

The Helix Midnight mattress costs $1,099 for a queen size. This is less expensive than the average hybrid mattress, making it a good choice for those shopping with a budget of $1,000 or less. For those who would prefer a luxury hybrid model, Helix offers the Luxe version of the Midnight mattress at a much higher price point. This upgraded model includes a Tencel cover, additional support layer, and pillow top.

How Does the Helix Mattress Feel?

Overall, the Helix Midnight balances a conforming feel with ergonomic support. The high-density memory foam contours to the shape of your body to relieve pressure points.

The Helix Midnight mattress is medium firm. This level of firmness is ideal for most sleeping positions and body types, since it balances comfort and support. It helps keep the spine aligned and takes pressure off the lower back, shoulders, and hips. Though the memory foam comfort layer contours to your shape, you’re more likely to feel like you’re sleeping “on” the mattress rather than “in” it.

Added bounce from the coil support core makes it easy to change positions. Since the Helix Midnight mattress has a thick comfort system with a high-grade transition foam layer, you won’t feel the coils beneath you. The firmness and hybrid construction prevent sinking in too deeply.

What Is the Helix Mattress Made of?

The Helix Midnight mattress is a hybrid mattress with a foam comfort system. The mattress has a 12-inch profile, which is about the average height for a hybrid mattress. Its multi-layer construction amplifies the benefits of memory foam and pocket coils, while minimizing drawbacks. We’ll break down each layer of the mattress here.

Cover Material

The Soft Touch Design cover of the Midnight mattress is made of 100 percent polyester. It’s designed to be breathable in order to increase airflow throughout the mattress. This helps keep you from sleeping hot. The cover cannot be removed and should be spot cleaned as needed. To prevent stains and spills, it may be worth it to invest in a mattress protector.

Comfort Layers

The first layer of the Helix mattress is two inches of Memory Plus foam. This proprietary blend of high-density memory foam contours to the shape of your body and relieves pressure points. Beneath this comfort layer is one inch of high-grade transition foam. This layer supports the body and cushions pressure points. The ergonomic support of the Helix Midnight mattress evenly distributes body weight and reduces pressure.

Support Core

The Helix Midnight mattress has eight inches of responsive pocketed coils. Combined with the comfort layers above, the coils cradle the body and help keep the spine aligned. The coils are individually encased, which limits motion transfer and prevents sleep disturbances. Additionally, the perimeter of the support base is reinforced for ample edge support. Beneath the coil base is a one-inch layer of DuraDense polyfoam. This layer increases the support and durability of the mattress and reinforces the coils.

The Helix Midnight mattress is made in the United States. The mattress is CertiPUR-US and OEKO-TEX Standard 100 certified, meaning it’s made without harmful chemicals.

Does it Isolate Motion?

Rating 3/5

We found that the Helix mattress is on par with similar hybrid models when it comes to motion isolation. This is an important consideration for anyone who shares the bed. A mattress that limits motion transfer ensures you’re not disturbed if your partner tosses or turns, or gets in and out of bed.

The comfort layer of the Helix Midnight mattress absorbs and isolates movement. Memory foam is known for its motion isolating properties, so the two-inch layer of it in the Midnight mattress prevents sleep disturbances.

That being said, the coils add bounce to the mattress. They are pocketed to minimize the ripple effect of any movements, but you may feel your partner get in and out of bed. Smaller movements are less likely to be felt.

We found that Helix mattresses that use softer foam in the comfort layers do a better job of isolating movement.

Does the Helix Sleep Cool?

Rating 3/5

The Helix Midnight mattress has a couple of components that prevent the feeling of sleeping hot. The breathable knit cover lets air flow throughout the mattress while the coils help air circulate and prevent heat retention.

That being said, memory foam tends to retain heat. The Helix Midnight mattress has two inches of high-density memory foam as its top layer, so there is the possibility of heat building up in this layer. However, this layer does not conform as closely as traditional memory foam. The moderate contouring of the mattress allows air to circulate around the body.

While the mattress maintains a temperature neutral feel overall, it may not be cooling enough for hot sleepers.

Will It Sag Along the Edges?

Rating 3/5

The reinforced perimeter of the Helix mattress prevents sagging along the edges. The coil base offers consistent support from edge to edge. The high-density memory foam also prevents sagging.

You may notice that the mattress sinks in when you sit on the edge of the bed. This is because the top layer of the mattress is made of memory foam, which compresses easily. However, it should spring back to its original shape. Most sleepers still feel supported when sleeping near the edge of the bed, especially if they weigh less than 230 pounds.

Hybrid mattresses generally have better edge support than foam models. Having support around the perimeter makes it easier to get in and out of bed. It also increases the surface area of the bed, as those who sleep near the edge feel as supported as if they were sleeping in the center.

Is It Good for Sex?

Rating 3/5

The Helix mattress is suitable for sex. We generally recommend hybrid mattresses because they facilitate movement better than foam models, making it easy to change positions as needed. The coils add bounce to the mattress, which is an important factor for sex. Since the coils in the Helix Midnight mattress are pocketed, there is minimal noise. The memory foam in the comfort layer is slower to respond than latex but it does provide traction. The Helix Midnight mattress would be a good choice for most couples.

What About Off-gassing?

Rating 3/5

There is an initial odor when the Helix Midnight mattress is first unboxed. Off-gassing refers to the release of Volatile Organic Compounds (VOCs), which causes an odor similar to rubber or plastic. It’s especially common in mattresses that use synthetic foam and are compressed and vacuum-sealed for shipment. The Helix Midnight mattress is CertiPUR-US certified and low in VOCs. Any initial odor should dissipate within a few days.

What Type of Sleeper Is the Helix Mattress Best for?

Overall, we found that the Helix Midnight mattress is best for side and back sleepers. It relieves pressure on the back, shoulders, and hips. There are special considerations for each type of sleeper, which we’ll outline below.

Side Sleepers

For side sleepers, the Helix mattress cushions the shoulders and hips. These areas press into the mattress and are prone to developing pressure points. Since the top layer of the mattress is made of memory foam, the Helix mattress contours to the shape of the body. Each Helix mattress is made with a specific sleeping position in mind, and the Helix Midnight mattress has conforming layers that are especially beneficial for side sleepers.

Combination Sleepers

Combination sleepers change positions throughout the night. While memory foam can restrict movement to a certain extent, the coils add plenty of bounce to the Helix mattress. This makes it easier to shift from your back to your side or your side to your stomach throughout the night as needed. In each position, the Helix mattress offers ergonomic support.

Back Sleepers

The Helix Midnight mattress is a good choice for back sleepers, as the memory foam conforms to the shape of the body and supports the lumbar region. Ergonomic support from the foam transition layer and responsive coils ensure the spine is kept in alignment.

How Does Body Weight Impact the Helix Mattress' Performance?

The Helix mattress is best suited for those who weigh less than 230 pounds. Body weight affects mattress performance because it determines how much pressure is put on the mattress. When we look at the relationship between mattress performance and body weight, we typically divide people into three categories: people who weigh less than 130 pounds, people who weigh between 130 and 230 pounds, and people who weigh more than 230 pounds.

Those who weigh less than 130 pounds put less pressure on the mattress. As a result, the mattress feels firmer. The memory foam comfort layer of the Helix mattress still conforms to the shape of the body and cushions the hips and shoulders. The Helix mattress is highly rated for side sleepers in this weight category. It’s also good for back and stomach sleepers who weigh under 130 pounds. Back sleepers will feel ample support and pressure relief for the lower back. The medium firm feel prevents stomach sleepers’ hips from sinking in, which helps keep their spines aligned.

Side and back sleepers who weigh between 130 and 230 pounds will find that the Helix Midnight mattress cushions pressure points and provides ergonomic support for the back. Stomach sleepers in this weight category usually benefit from a firm mattress. Since the Helix mattress is medium firm with a conforming layer of memory foam, there is the possibility that the hips and abdomen will not feel properly supported. The Helix Twilight and Dawn mattresses are better suited for stomach sleepers.

Though hybrid mattresses are typically recommended for people who weigh more than 230 pounds, the Helix Midnight mattress is not our top pick. It offers fair support across the board, but its medium firm feel may be too soft for people in this category. The Helix Plus mattress, on the other hand, is constructed with additional support for a firmer feel.

Is the Helix Mattress Good for Couples?

The Helix mattress is a good choice for couples, assuming both parties weigh less than 230 pounds and tend to sleep on their backs or sides. The medium firm feel offers pressure relief and contouring for side and back sleepers.

When we recommend a mattress for couples, there are a few factors that we keep in mind that are important for couples. These include motion isolation, ease of movement, edge support, and temperature regulation. The Helix Midnight mattress performs relatively well in each of these categories, as its hybrid construction maximizes the benefits of memory foam and coil support.

The Helix mattress is about average in terms of motion isolation, especially considering it’s a hybrid mattress with memory foam in its comfort layers. The bounce of the coils make it easier to move around on the mattress, while the foam layers prevent movements from transferring from one side of the bed to another.

The reinforced perimeter of the mattress offers solid edge support for couples. This is ideal if one or both parties sleep near the edge of the bed. It also increase the usable surface area for sex.

The hybrid construction ensures consistent airflow throughout the mattress, which helps the mattress maintain a temperature neutral feel. The coils and breathable knit cover dissipate heat and keep couples comfortable throughout the night.
