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 that is 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 it’s materials, share what 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.

What Does the Helix Plus Mattress Feel Like? 

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 both 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.

Though the Helix Plus is great for back 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. Conversely, I think that heavy side sleepers might want more cushioning. 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. So if you’re a heavy stomach sleeper or heavy side sleeper, I would consider looking at a different mattress.

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.

Testing the Helix Plus Mattress 

Now that we’ve discussed firmness, let’s see how the Helix Plus performed on our Sleepopolis tests: pressure relief, motion transfer, and edge support.

Pressure Relief 

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.

Paulie’s pressure map results on the Helix Plus.

Back – Though there is a yellow band at the lower back, the majority of the pressure map is blue. I think back sleeping is the best position for heavy people on this mattress.

Side – As you’ll see, there’s a bit of red at the hips in this position, which means Paulie is exerting quite a bit of pressure there. I think heavy side sleepers should opt for a softer bed.

Stomach – There is quite a bit of green in this position, but I think that over time, heavy stomach sleepers would find their hips sinking down too far into this mattress. I’d recommend they go with a firmer mattress that will offer extra support.

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.

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.

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.
