Helix Plus Mattress Review

Are you a plus-size sleeper looking for a mattress that’s going to give you the support you need? Are you tired of your mattress sagging after months or a few short years? Then it might be time to consider a mattress that is specifically designed for heavier sleepers, like the Helix Plus. 

The Helix Plus is Helix Sleep’s mattress made for larger sleepers. It uses reinforced coils and layers of foam to provide a nice mix of comfort and support. But is it the best mattress for you? 

I tested this mattress and I had a plus size individual test it as well. In this review, I’ll share our opinion of the Helix Plus’s firmness, talk about its materials, share which sleepers it’s best for, and tell you a bit about Helix’s policies and other mattresses.

Is the Helix Plus a Good Mattress for You? 

Before we get into all the details about the Helix Plus mattress, I want to give you some basic recommendations to help you decide if it’s the right mattress for you. Depending on your body weight, preferred sleeping position, and whether or not you sleep with a partner or pet, the Helix Plus may or may not work for you.

Who I recommend Helix Plus mattress for

  • I think the Helix Plus is a good choice for heavy back sleepers. Our plus-sized tester, Paulie, found that he was most comfortable on his back on this mattress and felt the greatest degree of pressure relief in this position.
  • I also like this mattress for lighter sleepers. As a lighter sleeper myself, I felt comfortable on the Helix Plus in a range of positions. So if you’re in a mixed weight couple, the Helix Plus could be a great mattress for you.
  • Heavier sleepers who want a more “in” than “on top” of the bed feel could be happy on the Helix Plus, as Paulie felt quite a bit of sinkage on this mattress. However, as a lighter sleeper myself, I felt a bit more “on top” of the bed. 

Who I don’t recommend Helix Plus mattress for

  • I wouldn’t recommend the Helix Plus to heavy combination sleepers. Our tester Paulie found that it was difficult to switch positions and he felt a bit stuck in the mattress.
  • This mattress isn’t the best option for heavy side sleepers. Paulie felt some pressure at his hips while lying on his side, and over time this could lead to soreness in that area. If you’re a heavy side sleeper, I’d recommend checking out our best mattresses for heavy people roundup, where we have some great picks for those who sleep on their sides.
  • I’d recommend heavier stomach sleepers go with a firmer mattress. These sleepers need quite a bit of support to keep their hips from sinking too far into the mattress.

How Firm is the Helix Plus Mattress? 

Now that you know who the Helix Plus is and is not best for, let’s discuss how it actually feels. One of the greatest contributors to feel is a mattress’s firmness level. However, firmness is subjective and is influenced by factors like body type, height, and weight. To determine the Helix Plus’s firmness level, both I and our plus-size tester Paulie gave it firmness ratings.

Helix Plus Firmness
Paulie found the Helix Plus to be medium-firm.

After lying on the Helix Plus, I decided to give it a 6.5 on the firmness scale, and Paulie gave it a 6. This means that for a lighter sleeper, this mattress will feel truly medium-firm, while a heavier sleeper is likely to experience it as a bit softer than medium-firm.

The Helix Plus is made of a combination of innerspring coils and foams. The foam layers provide some nice pressure relief and sinkage, and give this mattress a medium to medium-soft overall feel. However, you will still experience some good support from the Helix Plus’s layer of steel coils, which are specifically designed to support heavier people. This firmness level is best for heavy back sleepers, who should experience some nice pressure relief at the lower back. Heavy back sleepers will get enough support to keep their spines in a nice straight alignment, which prevents back pain. Additionally, Paulie found back sleeping to be the most comfortable on the Helix Plus.

I would like to note that lighter sleepers should find the Helix Plus comfortable in a range of positions. In fact, I found this mattress to be really comfortable while testing it. This is good news for lighter sleepers who have heavier partners, because even though this bed is designed for plus-size individuals, it still works for lighter people.

Helix Plus Mattress Performance

Now that we’ve discussed firmness, let’s see how the Helix Plus performed in a few more categories. I’ll kick things off by discussing how this mattress might feel to sleepers of different body weights depending on their preferred sleeping position.

Testing the Helix Plus Mattress in Different Sleeping Positions

Take a look below to see how this mattress performs for different sleeper types.

Is the Helix Plus a Good Mattress for Light Sleepers (Under 130 lbs)?

  • Light Back Sleepers – As a lightweight sleeper myself, I found this bed quite comfortable on my back. It had a nice medium-firm feel that offered good support.
  • Light Side Sleepers – I found this bed pretty comfortable on my side, and would say if you’re a lighter sleeper with a heavy partner, this is one of the best side sleeping options for you. Most other beds designed for heavier folks will feel much firmer when you’re on your side, which can lead to soreness around the hips and shoulders for lighter folks.
  • Light Stomach Sleepers – I also liked how this bed felt on my stomach. It did a good job keeping my hips lifted up in line with my shoulders.

Is the Helix Plus a Good Mattress for Average Weight Sleepers (130 – 250 lbs)?

  • Average Weight Back Sleepers – Average weight back sleepers should get a nice mix of support and pressure relief on this bed, which should feel about medium-soft to them!
  • Average Weight Side Sleepers – I think average weight side sleepers could also feel okay on this bed, though they might feel more pressure around the hips and shoulders than lighter folks as they sink closer to its coil layer.
  • Average Weight Stomach Sleepers – This bed will most likely be just a little too soft for these sleepers. But, if you only spend part of the night on your stomach, the Helix Plus should work for you.

Is the Helix Plus a Good Mattress for Heavy Sleepers (over 250 lbs)?

  • Heavy Back Sleepers – As I mentioned above, Paulie thought the Helix Plus felt great when he was on his back. If you enjoy a hug-like feel that offers some nice body-contouring, you should really like this mattress.
  • Heavy Side Sleepers – Heavy side sleepers might want more cushioning than this mattress provides. Paulie experienced some pressure at his hips while laying on his side on the Helix Plus, and that’s something side sleepers want to avoid to prevent soreness.
  • Heavy Stomach Sleepers – I do think that stomach sleepers should opt for a firmer bed. Stomach sleepers, and especially heavy stomach sleepers, need a firm mattress that will prevent their hips from sinking too far into the mattress, which throws their spine out of alignment, leading to back pain. The Helix Plus is not quite firm enough to provide enough support.

Helix Plus Mattress Pain Relief Performance

I like to use a pressure relief test to measure a bed’s ability to relieve pain in different areas. Pressure relief refers to how well a mattress alleviates tension at sensitive pressure points at the hips, shoulders, and lower back. It’s important that your weight is evenly distributed on your mattress, as this prevents soreness from developing in certain areas.

To measure the Helix Plus’s pressure relief, I had Paulie lay on a pressure map, which recorded the pressure his body exerted on the bed in different positions. The map turns blue to green for low pressure and yellow to red for high pressure.

Back Pain – That yellow band at the lower back, plus the soft feel of this mattress, let’s me know that this bed is not an ideal fit for heavy sleepers who struggle with back pain.

Shoulder Pain – The green around the shoulders across every sleeping position tells me this bed is a great fit for heavy sleepers with shoulder pain. They should get enough cushioning in this area to feel comfortable.

Hip Pain – The red areas around Paulie’s hips when he’s on his side (plus the green and yellow around the lower back in other positions), tell me this bed is not a good fit for heavy sleepers with hip pain. They’ll sink too close to this bed’s pocketed coil layer, which will result in some pressure build up in this area.

Helix Plus Mattress Performance for Couples

Couples often fair best on a mattress that features good motion isolation, enough responsiveness for sex, good edge support, and cooling features. We know this mattress is a great fit for partners of different weights based on its firmness level, but how will it hold up during these other tests? Read on to find out!

Motion Transfer

Motion transfer refers to how much movement is detectable from one side of the bed on the other. It’s an important factor for couples or anyone who sleeps with a pet, as they don’t want to be disturbed by a restless bedmate.

To measure motion transfer, I dropped a 10 lb. steel ball from three different heights that are meant to mimic different movements in bed. I used a seismometer to measure the movement these drops caused on the other side of the bed

Helix Plus motion
The Helix Plus has about average motion transfer.

I think these are average motion transfer results. If you aren’t easily disturbed by your partner or pet’s movements, you should be quite happy with this level of motion isolation.

Sex

The best mattress for sex is often bouncy and responsive, which makes moving around and changing positions easy. If you’re on the lighter side, this bed is fairly easy to move around on and a good fit for sex. But if you’re on the heavier side, you might feel a bit “stuck-in” this mattress, meaning it’s not the best fit for sex.

Cooling

Couples often prefer cooling mattresses, since they overheat faster than solo sleepers. The Helix Plus’s pocketed coil structure means it sleeps pretty cool, which is great news for both couples and hot sleepers.

Edge Support

Edge support refers to how well a mattress holds up on the sides as compared to the center. On a mattress with good edge support, you won’t feel like you’re going to roll off the edge while lying there. Good edge support can also add to a mattress’s durability, as it prevents sagging.

I was not impressed with the Helix Plus’s edge support. When Paulie sat on the edge of this bed, it compressed to nearly half of its original height. This can pose a problem for larger sleepers, and especially larger couples, who will want to take advantage of their mattress’s total surface area.

What is the Helix Plus Mattress Made Of? 

The Helix Plus is a hybrid mattress, which means it’s made of a combination of foams and coils. This Helix mattress has four layers of foam, including two layers of memory foam. It also uses coils that were specifically designed for heavier sleepers. It has a height of 12 inches.

Cover – The Helix’s mattress cover is made from Tencel, a soft and breathable fabric that was designed to promote airflow through the mattress.

Comfort Layer – The top layer of the Helix Plus is made of ultra dense memory plus foam. This foam layer provides cushioning and some of the deep compression support that heavier sleepers need.

Second Comfort Layer – Below the first memory foam layer you’ll find a layer of Helix dynamic foam. It has a latex-like feel and contours to the body. It also prevents the sleeper from sinking too far into the mattress.

Transition Layer – This layer is made from a firm memory foam that provides contouring and adds even more deep compression support to the bed.

Support Layer – This Helix mattress gets it support from its layer of XL wrapped coils. These strong coils are specifically designed to support heavier weights.

Base Layer – Lastly is a layer of proprietary DuraDense foam, a high-density foam which provides added support and durability to the bed.

Helix Plus Unboxing and Off-Gassing

The Helix Plus will arrive in a box, so you’ll need to unwrap it and set it up on your bed frame. The unboxing process is very simple, but I’d recommend having a friend help you with it, because this mattress is fairly heavy. After unboxing, your new bed will need 24-48 hours to off-gas and decompress. I do want to note that this bed does have a fairly strong off-gassing odor. But, as long as you leave your bed in a well-ventilated room any smell should dissipate within a few days at most.

My Final Thoughts about the Helix Plus Mattress

Before we finish up this review, I’d like to recap some of what we’ve learned about the Helix Plus. Though I can’t tell you if this is the right mattress for you, I hope these final thoughts will help you decide.

My favorite things about the Helix Plus mattress

I really like the soft, hug-like feeling you get on the Helix Plus. This is great for anyone who likes to feel a bit more enveloped by their bed. I also think the Helix Plus is a nice choice for heavy back sleepers, who will get a great combination of pressure relief and support on this medium-firm bed. Finally, I think this is a great bed for mixed-weight couples, as I (a lighter sleeper) found it to be quite comfortable.

My Helix Plus mattress complaints 

I think that some heavy sleepers might find that this mattress isn’t firm enough for their needs. A few reviews of the Helix Plus mentioned that it was too soft, so if you’re worried about firmness I’d go with a mattress that offers more support. Some reviews also mentioned that the Helix Plus had a strong odor for a while after they unboxed it, which is something I also noticed while unboxing it. Also, I think this mattress has pretty poor edge support, and good edge support is something heavier sleepers typically need.
