Product Description

I often wake up with pains and aches because of my weight. I understand the sleeping issues of those who are dealing with heavy-weight. If you are having the same trouble, finding a mattress with adequate support is essential.

I can tell you that many mattresses aren’t made to support our body weight. This causes us to sink in and become misaligned all night long.

However, there is positive news for you! Helix Plus is the one which is suitable for heavy-weight individuals. The mattress is designed with high-density materials. It is suitable for heavy-weight individuals.

Pros & Cons

Q1. Who would you recommend a Helix Plus Mattress to?


  • Helix Plus is specifically designed to provide good support for heavy-weight back sleepers.
  • The mattress is suitable for light and average-weight stomach sleepers.
  • It offers good edge support.
  • Helix Plus is responsive and suitable for all sleeping positions.
  • Hot Sleepers may prefer this mattress.

Q2. Who should avoid Helix Plus Mattress?


  • Light and average-weight side sleepers might find Helix Plus too firm.
  • The mattress performs decently in motion isolation.


The firmness of a mattress is a factor in getting a good night’s sleep. It affects pressure alleviation, comfort, and spinal alignment.

However, since adjectives like “firm” and “soft” are arbitrary, I sometimes find it difficult to make the proper decision.

Typically, mattresses are rated from 1 to 10, where one represents very soft and 10 represents firm.

Knowing how firmness affects your body and sleeping pattern is crucial. I have shared some information below. Have a look!

Recognize the layers

  • Support originates from the mattress core, and firmness is the sensation of the uppermost comfort layers.
  • Both stiff and unsupportive and soft and supporting mattresses are available.

Selecting the suitable firmness

Firmness is influenced by several factors:

  • Those who sleep on their sides usually want softer mattresses (4-5 on the firmness scale) that support their shoulders and hips.
  • For better spinal alignment, medium-firm (6-7) alternatives are generally preferred by back and stomach sleepers.
  • Light-weight people may find comfort with softer mattresses, but heavy-weight sleepers (above 230 lbs) may require a firmer mattress (7–10) for optimal support.
  • Some people just like the way a soft bed feels, while others would rather have a firmer surface.

You can find your suitable fit after trying the mattresses with different firmness level. In this mattress review, I am going to discuss about the firmness of Helix Plus Mattress.

Helix Plus Mattress-Firmness

Helix Plus Mattress is designed to offer a medium-firm feel. It strikes a balance between support and comfort.

This firmness level is carefully chosen to cater specifically to the needs of plus-size sleepers. It ensures adequate support without sacrificing plush comfort.

Let’s have a look at how the materials are responsible for medium firmness.

  • The Comfort Layer consists of Ultra-Dense Helix Dynamic Foam, which is engineered to provide targeted pressure relief. It maintains support for all sleep positions.
  • This foam layer is designed to prevent plus-size sleepers from sinking too deeply into the mattress.
  • It offers a supportive surface that conforms to the body’s contours.
  • Additionally, Transition Layer comprises Higher Density Helix Responsive Foam. This layer enhances the mattress’s contouring capabilities while ensuring good spinal support, further contributing to the medium-firm feel.
  • The Body Shape Layer is where the mattress truly shines in terms of firmness and support. It features TitanCore Steel Coils, which are specially designed for heavier sleepers.
  • These durable steel coils offer sturdy support, motion isolation, and edge support. This ensures that the mattress maintains its firmness and shape over time.
  • The enhanced coil gauge from edge to edge reinforces the mattress’s overall support system, providing maximum support for plus-size sleepers.

In total, Helix Plus Mattress is crafted to deliver a medium-firm feel that meets the unique needs of plus-size sleepers. With its combination of high-density foams and reinforced steel coils, it offers a supportive yet comfortable sleep.

Whether you’re a back, side, or stomach sleeper, Helix Plus Mattress provides the proper combination of firmness and comfort for a restful night’s sleep.

Motion Isolation and Sharing a Bed


Q4. Does Helix Plus Mattress provide reasonable motion isolation when sharing a bed with others?

Motion Isolation

Based on the information provided, Helix Plus Mattress offers decent but not outstanding motion isolation. Some movement from a partner may indicate that there might be some disturbance for sensitive sleepers.

However, if you and your partner are deep sleepers, this might not be a significant issue.

So, while Helix Plus Mattress provides reasonable motion isolation, it may not be the suitable choice for couples.

Edge Support


Q5. How would you rate the edge support of Helix Plus Mattress?

Edge Support

Based on the information provided, I would rate the edge support of Helix Plus Mattress quite well.

During testing, there was minimal sinkage when sitting on the edge, and lying along the edge provided strong support without noticeable sagging. This indicates that the mattress offers sturdy edge support. This is particularly beneficial for heavy-weight sleepers and those who sit or sleep near the edge of the bed.

In total, Helix Plus demonstrates good edge support, ensuring durability and maximizing the usable surface area of the mattress.

Recommendation based on sleeping style

The way I sleep affects our general health. I think it may happen to you as well.

Good sleeping position relieves pressure on your back and joints by maintaining your spine in a neutral position. For those who have back discomfort or injuries, this may be a relief.

While some people may find stomach sleeping comfortable, many do not prefer it. Because of the abnormal twist in your spine, it may cause tension on your neck and back.

To reduce the tension, if you sleep on your stomach, think about using a very thin pillow or none at all.

The position that lets you fall asleep and stay asleep all through the night is ultimately the good one. Try out various poses to see which one suits you.

Recall that supportive mattresses can improve the quality of your sleep in any posture.

Hence, in this mattress review, let us discuss Helix Plus Mattress. Check whether it suits your sleeping position or not!

Side Sleepers and Helix Plus Mattress

  • Helix Plus may feel too firm for light-weight side sleepers (under 130 pounds). It lacks adequate pressure relief on the shoulders and hips.
  • Most average-weight side sleepers (130–250 pounds) will likely not receive enough pressure relief from Helix Plus, making it less suitable for this group.\
  • While heavy-weight side sleepers (Over 250 pounds) may appreciate the support of Helix Plus, its firmness might still not offer the desired pressure relief for some individuals.

Back Sleepers and Helix Plus Mattress

  • Light-weight back sleepers could find Helix Plus comfortable, as its firm feel should offer good support for spinal alignment.
  • Average-weight back sleepers are likely to be very comfortable on Helix Plus, as it provides both support and comfort for spinal alignment.
  • Helix Plus is a good choice for heavy-weight back sleepers, offering both cushioning and sturdy support for the lumbar area.

Stomach Sleepers and Helix Plus Mattress

  • Light-weight stomach sleepers should find Helix Plus comfortable, as its firm and supportive structure helps keep their hips lifted and aligned.
  • Average-weight stomach sleepers will also find Helix Plus supportive enough to keep their hips lifted and aligned for proper spinal alignment.
  • While Helix Plus could work for some heavy-weight stomach sleepers, it may not be firm enough for all to keep their hips lifted up. However, it remains a decent option for this group.

In total, Helix Plus Mattress offers varying degrees of comfort and support for different sleepers. It is based on their weight and preferred sleeping positions.

While it may not be the ideal choice for all individuals, it provides a balanced combination of support, comfort, and durability for many sleepers.
