Pros & Cons

  • Prefer sleeping on their sides

  • Want a highly durable mattress

Not so ideal for sleepers, who

  • Are looking for good strong edge support

Firmness is a subjective matter. To some, a particular mattress may feel soft, while it may feel firm to others. Whether a mattress feels firm or soft, it should support body weight, promote healthy spinal alignment, and ensure comfortable and restful sleeping. Whether a mattress is soft, plush, or firm is purely defined based on personal preferences, choices, and body type.

The Helix Moonlight is one of the softest mattresses among the other Helix type. Moonlight is a medium soft mattress that is highly comfortable. The latex foam, together with pocketed coils and foam layers and a soft and breathable cover, gives the perfect balance of comfort and support for a comfortable and sound night’s sleep. It is good for lightweight back sleepers and average-weight back sleepers who enjoy a soft feel. Helix Moonlight Luxe is an upgrade over the regular Helix Moonlight mattress and is 14 inches thick. The Luxe version also falls in the medium-soft category offering more sinkage due to the pillow top layer. The Dynamic Foam used in the construction of the mattress gives it a soft and plushy feel that gives the body of the sleeper the right amount of cushion and extra comfort.

Material & Construction

The Helix Moonlight is a 12-inch hybrid mattress. It is made of latex, up to 950 individually wrapped 8 inches steel coils, and foam. It is a soft-to-touch feel mattress. The top layer gives a plush and soft feeling.

The mattress is made up of 4 layers which are detailed below:

  • Layer 1: It is the topmost comfort layer made of Helix Dynamic foam; it is a proprietary polyfoam that mixes the benefits of latex and foam for better contouring and a responsive feel.
  • Layer 2: The transition layer is the second layer made of soft Helix Dynamic Foam, ensuring comfortable cushioning, ergonomic support to the user, and motion isolation. This layer is a little firm and serves as a transition layer between the soft top layer and the pocketed coils beneath.
  • Layer 3: This is the innerspring support layer and is made up of pocketed coils, which help provide targeted support and offer fantastic body contouring and alignment. The perimeter gives additional edge support while the whole layer permits more air to flow, thus adding to the breathability of the mattress and aiding in cooling.
  • Layer 4: The base layer is made up of DuraDense Foam, which is a high-density polyfoam that results in the extra support needed for durability.

Additionally, in the Luxe variant, a zoned body shape coil layer provides longevity and support to the mattress. Up to 1500 individually wrapped 8-inch steel coils make the mattress feel soft near the shoulders and firm under the hips. The zoning technology helps to cradle the body and provide proper spine alignment.

The cover of the standard Moonlight mattress is 100% polyester with a soft white top and blue and grey bottom. The cover is thin and so designed that it helps in greater airflow, thus allowing the sleeper to have a relaxed feeling and sleep cool at night.

The Helix Moonlight Luxe cover has two different options to choose. It comes in an ultra-breathable TENCEL cover, designed for maximum airflow, or  GlacioTex Cooling Cover made with fibers with a high thermal conductivity that wicks heat away from the body, giving a comfortable sleep.

Repositioning means that a person can switch positions during sleep easily. Again, those who toss and turn pay attention to mattress responsiveness. It measures how quickly one can become comfortable after changing positions and how one can make an easy move. The Helix Moonlight offers ease of movement, provided by its construction. Helix Dynamic foam along with springy coils makes the Moonlight mattress bouncy. Combination sleepers can easily move around while changing positions.

Comfort, Back Support, Pressure Relief


With the different variety of mattresses available in the market, it isn’t easy to choose the right one. The right mattress can help get a good night’s sleep, which leads to the feeling of rest and refreshment upon waking up. Pain relief is another important feature that people look for while buying a mattress. Helix Moonlight is excellent in relieving pressure from the back and works well with sleepers suffering from shoulder pain. Both the model, standard, and Luxe provide good cushioning to the shoulders and give relief from stiffness and pain.

The Helix Moonlight offers soft plush comfort to the sleeper due to the presence of a soft-top layer on the mattress. The mattress is designed to provide spinal support aids in recovery and contours according to your body. It doesn’t trap a lot of heat due to its breathable cover and coils, which allow airflow through the whole mattress, which help keep the sleepers cool throughout the night. It does not have the vicious, sinking feeling associated with memory foam; instead, a sleeper would feel cushioned not unable to move owing to the latex nature of the Helix Dynamic Foam.

The suitability of the mattress for different sleeping positions is detailed below:

  • Back sleepers: The Helix Moonlight is good for lightweight and average-weight back sleepers who prefer a softer mattress. Despite the bouncy comfort layer, the mattress has a soft feel that conforms gently around the shoulders and lower back. The transition layer of Helix Dynamic Foam and the coil support offer support to keep the spine well-aligned.
    Helix Moonlight is not a good option for heavyweight back sleepers. They should check for Helix’s firmer mattresses, like the Twilight and the Dawn.
  • Side sleepers: The Moonlight is an excellent choice for lightweight and average-weight side sleepers, especially those who require contouring at the hips and shoulders but don’t love the sinking feeling of memory foam. The Helix Dynamic Foam top layer gives the bed a plush feel, but it feels less conforming when compared to memory foam. The mattress is not ideal for heavyweight back sleepers as they may not find the spinal alignment needed for comfortable side sleeping. Thus, heavyweight side sleepers should look for a more supportive option.
  • Stomach sleepers: Stomach sleepers need a bed that gives an appreciable lift to the hips and torso to prevent the lower back pain caused due to sagging. Thus, the Moonlight will provide a feel of being too soft for most of the average and heavyweight stomach sleepers. Lightweight stomach sleepers may find Moonlight comfortable, but strict stomach sleepers can go for other firmer options from Helix Sleep.
  • Heavy sleepers: Larger people, like plus-sized individuals, have their own needs when it comes to choosing their beds which is unique. Both Moonlight and Moonlight Luxe being medium-soft mattresses is not ideal for heavy sleepers; instead, they can go for Helix Plus, which is designed especially for plus-sized sleepers.

Cooling & Temperature Control


The most critical condition that determines the quality and duration of the body’s recovery during sleep is an adequate decrease in the core body temperature. The Helix Moonlight is a great mattress as it helps in keeping you cool and comfortable throughout the night. The construction of the mattress with a latex foam layer and pocketed coil layer prevents the buildup of excess heat at night.

Motion Isolation and Sharing a Bed


Helix Moonlight, a bouncy mattress, is not great at minimizing motion transfer. Though it’s not too bad because it is so vibrant, any movement is carried on to the other sleeper, who can feel it. This factor is to be kept in mind if you have a partner to share your bed with.

On the other hand, the upgraded version of Moonlight, the Helix Moonlight Luxe, offers excellent motion isolation due to the soft comfort layers. The layers absorb motion transfer better and enable disturbance-free sleep.

Edge Support


Helix Moonlight offers excellent edge support that is provided by the strengthened perimeter of pocketed coil layer. Lengthwise, two-sided edge support gives support to the perimeters. The user shall experience safety while lying or sitting at the mattress edge due to the immense support of coils, which provide strong edge support.

The Luxe variant provides four-sided (perimeter) edge support that gives complete structural stability. The softer foam layers may make the mattress feel somewhat soft near the edges; however, the zoned coil system makes up for it.

Recommendation based on sleeping style

A night of restful sleep is crucial to maintaining a healthy lifestyle, but according to the National Institute of Health (NIH), about 7 – 19% of adults in the United States do not get enough sleep. The brand Helix is linked with the concept of sleep DNA, which the company mentions on its website. Each of us has a different sleep DNA or specific needs for comfort and support; thus, it becomes difficult for many people to find what they need when choosing between just one or two mattresses. Though Helix does not make a different mattress for every person, they offer a wide range of options that meet most sleepers’ needs. Helix Moonlight is a good choice for every sleeping position.

Below is a detailed description of how the Helix Moonlight is a good fit for different sleep postures.

  • Side Sleepers: An average weighted side sleeper should enjoy the maximum benefits due to the comfort they experience because of the soft layers. If you are on the healthier side but weigh less than 300 pounds, you will enjoy pressure relief, but people who weigh more could experience a sinking feeling and feel jammed on the firmer support layer beneath. This mattress is ideal for lightweight side sleepers as they experience pressure relief.
  • Back Sleepers: If one weighs average, it could be a decent fit for them, but someone who wants good support while sleeping should opt for a firmer mattress. If you are a heavyweight sleeper, it won’t offer you the much-needed comfort and support. It can give you ideal support if you are a light weighted back sleeper; in that case, it can be a good choice for you.
  • Stomach Sleepers: It would be way too soft for you if you are an average-weighted stomach sleeper, and you might experience a sinking feeling. This mattress isn’t much support for lightweight stomach sleepers; therefore, certainly not feasible for heavyweight stomach sleepers.
  • Combination Sleepers-Those who alternate between various positions: Combination sleepers tend to change positions while sleeping. The Helix Moonlight is an excellent bed for combination sleepers. Combination sleepers prone to tossing and turning will find the mattress to provide great comfort in every position, thus ensuring a good night’s sleep.
