Are you after a super-soft mattress? The Helix Sunset may be the answer to your prayers. This is the softest mattress offered by the Helix brand.
Though it was designed to cater to side sleepers, this hybrid bed should fare well for anyone whoโs seeking plush comfort. We tested the Helix Sunset and found out its star power when it comes to cushioning and pressure reliefโand those coils underneath donโt skimp on the support.
In this review, weโll go over what we found in terms of support, pressure relief, bounce, motion isolation, and other such factors you want to know about before buying a mattress.

Our Recommendation
Helix Sunset Performance Ratings
Who We Recommend The Helix Sunset For:
- Side sleepers โ This hybrid mattress has coils and foam, but the soft feel makes it more similar to a memory foam mattress than a hybrid one. As such, we think itโs an excellent match for strict side sleepers because it does a good job of taking the pressure off the hips and shoulders.
- People with joint pain โ People with achy joints need a mattress that wonโt add to the problem. We think the Helix Sunset is a good match as itโs soft enough to cradle the sensitive points and relieve pressure and pain.
- Lightweight back sleepers โ Back sleepers weighing 130 pounds or less should like the combination of support and pressure relief offered by the Helix Sunset.
Who We Donโt Recommend The Helix Sunset For:
- Heavy sleepers โ We donโt think this mattress is a good match for people over 230 pounds as itโs too soft and not supportive enough. Instead, we think youโre better off with a more supportive Helix mattress, such as the Helix Plus.
- Stomach sleepers โ If youโre a strict stomach sleeper, we think this mattress may be too soft for you. Most stomach sleepers would find their hips sinking too far in, which we think can cause spine misalignment and lower back pain. Stomach sleepers usually need a firmer mattress.
- Light sleepers โ We tested motion isolation of the Helix Sunset and werenโt impressed. If youโre a light sleeper, you may feel your partner moving, especially if theyโre a restless sleeper. Instead, weโd recommend the Helix Midnight as a better option for those easily awakened.
Customer Reviews of the Helix Sunset Mattress
The Helix Sunset has 4.5 out of 5 stars on Helixโs website. Customers appreciate the Helix Sunset mattress for its personalized comfort based on individual sleep preferences, but some have reported a minor initial off-gassing odor.
Testing the Helix Sunset Mattress
Sleep Advisorโs Testing Methodology
When we test mattresses, there are specific features we consider, including motion isolation, bounce, cooling, and edge support. Our team also tests the mattress in various positions to see how the bed performs in terms of pressure relief and support in each position.
When then use the information weโve gathered to provide scores for specific performance categories and share who we think a mattress is best suited for.

Firmness & Feel
Firmness Scale: 5.5 / 10

Firmness is important to consider when buying a new mattress. However, itโs subjective, and what you may find firm might not be firm enough for someone else.
We rate mattress firmness on a scale of 1 to 10, where 1 is the softest and 10 is the firmest. With that said, we think the Helix Sunset falls at a 5.5 out of 10 on our firmness scale. This medium firmness means the Sunset feels slightly softer than medium-firm beds rated at about 6 to 6.5.
How Does It Feel?
One of the first things we noticed when testing this mattress is the balanced foam feel combined with a plush, soft top. The comfort layer allows just enough sinkage, like what youโd get from a typical memory foam mattress.
Sleeping Positions for Different Body Types
According to Helix, the Helix Sunset can comfortably support up to 500 pounds for sizes Twin to Full and up to 1,000 pounds for Queen and up. However, just because this bed can physically support heavier-weight people doesnโt mean it will feel supportive or keep your spine in alignment. Weight and sleeping position both play important roles in how this bed will feel to you.
Side Sleepers
- Lightweight Sleepers โ We think the Helix Sunset is an excellent mattress for lightweight side sleepers. According to our testers, the mattress allows plenty of sinkage and pressure relief, allowing maximum comfort around sensitive joints.
- Average-Weight Sleepers โ Average-weight side sleepers are likely to sink deeper into the mattress, getting even more cushioning. This should be comfortable for most people as the coils support the body to keep everything in alignment.
- Heavyweight Sleepers โ Heavy side sleepers are likely to experience this mattress as even softer due to their hips sinking deeper. We think most people over 230 pounds will press too deep into the mattress, missing the benefits of the comfort layers.
Back Sleepers
- Lightweight Sleepers โ We expect lightweight back sleepers to enjoy the Sunsetโs top foam layers contouring their curves to reduce pressure and lower back pain.
- Average-Weight Sleepers โ Average-weight sleepers should still get sufficient support from the coils while enjoying the soft, cushioning comfort layers. However, we think those closer to 230 pounds may find the Sunset a bit too soft around the lower back and hips.
- Heavyweight Sleepers โ We donโt think the Helix Sunset is a good match for heavy back sleepers as they would probably sink too deeply around the lower back. Instead, we suggest you try the Helix Plus.

Stomach Sleepers
- Lightweight Sleepers โ Although lightweight stomach sleepers donโt need as much support, we think this mattress is still too soft for most people under 130 pounds.
- Average-Weight Sleepers โ Like lightweight stomach sleepers, average-weight sleepers are likely to find this mattress too soft.
- Heavyweight Sleepers โ We think the Helix Sunset is far too soft for heavy sleepers who enjoy sleeping on their stomach.
Pressure Relief
5/5
The Helix Sunset is, in our opinion, one of the best Helix mattresses for pressure and pain relief in light and average-weight sleepers. This bed has several layers of plush foam combined with coils to help with weight distribution and pressure relief in various sleeping positions.
However, we think anyone above 230 pounds may find this bed too soft, experiencing more pressure buildup. This is because theyโre likely to sink through the comfort layers all the way to the coils.

Is the Helix Sunset Good for Pain Relief?
The Helix Sunset mattress is a good option for pain and pressure relief, depending on the sleeperโs weight. We found this bed to do a good job of relieving pressure and pain in the shoulders, hips, and knees when sleeping on the side.
However, this was only the case with lightweight and average-weight people on our team. Heaver people experienced very little relief, most of them bottoming out to the coils instead.
Back Pain
We think the Helix Sunset does a good job of alleviating pain in the lower back for lightweight and average-weight sleepers. Heavy people weighing over 230 pounds are likely to sink deeper, which can cause more pain than relieve it. Find the best mattresses for back pain here.
Hip Pain
We think the Helix Sunset is an excellent option for side sleepers with hip pain as it contours the body and cradles the hips as you sleep. In the pressure map above, you can see that the hip is cradled when a person is in the side sleeping position.
However, if you switch over to your stomach, we donโt think it would be nearly as comfortable. The Sunset is too soft for stomach sleeping because the hips would sink too deeply to keep the spine aligned. Explore our picks for the best mattresses for hip pain.
Shoulder Pain
If you usually wake up with shoulder pain when you sleep on the side, we think the Helix Sunset could help you sleep better. The mattress has a softer feel and allows just enough sinkage to relieve pressure and pain in the shoulders.
Support
4/5
The Helix Sunset has a softer feel, but we wouldnโt say itโs not supportive. Although it has softer comfort layers, it has coils that do a good job of supporting your body in various sleeping positions. We think it offers a solid level of support for lightweight and average-weight side sleepers, but stomach sleepers and some back sleepers may want something firmer.
Motion Isolation
3.5/5
Motion transfer dictates how much of your partnerโs movement youโll be able to feel on your side of the bed.
Weโd say the Sunset does an average job of isolating motion. The comfort layers make you feel as if youโre sleeping on a memory foam mattress, but the Sunset also has coils that make it bouncier than all-foam beds. This means that light sleepers may feel a restless partner move during the night.

Temperature Regulation / Cooling
4/5
Although we wouldnโt call the Sunset a particularly cooling mattress, we think it still does a fairly good job of regulating temperature. We didnโt feel any heat building up as we lay on the bed, mostly thanks to the Soft Touch Design cover thatโs very breathable and comfortable.
Although it has memory foam, which is known for trapping heat, this mattress also has coils that allow more air to flow through the bed. Nonetheless, if youโre an extremely hot sleeper, we think youโd prefer something more cooling.

Bounce
4/5
This Helix has some bounce to it, but we wouldnโt call it the bounciest of the brandโs models. Nonetheless, the buoyancy from the coils makes it easier to reposition, so youโre unlikely to feel trapped, even with all the softness in the comfort layer. Although this bounce limits the bedโs ability to isolate motion as well as all-foam beds, we think itโs a benefit for people with mobility issues and sexually active couples.
Edge Support
3/5
When we tested this bed for edge support, we noticed the edges compressed a bit when lying and sitting near the edge. However, this isnโt so surprising given the softer firmness level. We think this could be a drawback for couples who like to spread out, though getting a larger mattress size may also solve this issue.
Performance for Couples
3/5
We think the Helix Sunset mattress has decent bounce and responsiveness that can appeal to couples who are sexually active. However, we found it doesnโt have the best motion isolation and edge support, which could be a drawback for couples. If youโre worried about disturbing your partner with movement or want a bed you can spread out on, we think youโre better off with a different bed.

Preference-Based Features
Free Shipping
Helix offers free shipping within the contigious United States.
Great for Side Sleepers
Side sleepers who need a softer mattress to relieve pressure in the shoulders and hips should appreciate the Helix Sunset. We think this mattress has just the right softness to cradle side sleepers without making them feel trapped.
Excellent for Joint Pain
The softer feel of the Sunsetโs comfort layer should do wonders for joint pain. We think it does a good job of contouring and cushioning achy joints instead of pushing back against them.
Construction: Whatโs Inside the Helix Sunset?
The Helix Sunset is 11.5 inches tall, but if you upgrade to the Luxe version of this mattress, youโll get a 13.5-inch high bed. The Sunset is a hybrid that combines foam and coils to deliver a balance of pressure relief and support.
The cover of the Helix Sunset is made from 100 percent polyester and is soft to the touch. Although itโs not a cooling cover, we think it does a good job of promoting airflow as we didnโt feel any heat building up. However, you can opt for the brandโs GlacioTexโข Cooling Cover if you run extra hot at night, though this comes with an additional fee.
- The comfort layer is made from Memory Plus Foam, which is designed to contour the body to relieve joint pressure and pain. This layer has a softer feel and is comfortable for side and back sleeping.
- Further below is the transition layer made of Helix Dynamic Foam. This layer has a soft, cushioning feel that provides ergonomic support.
- The support layer comes next, featuring individually wrapped coils to provide support and bounciness. We think the coils also help with airflow to keep the construction cool.
- The final layer is the base of the mattress, which is made with DuraDense Foam, a poly foam that supports the entire mattress and adds to its longevity.

Unboxing & Off-Gassing
The Helix Sunset comes in a box, so itโs compressed and may take up to 48 hours to fully decompress before you can use it. We suggest you unpack and unroll it on your bed foundation of choice, letting it come to its full size before sleeping on it.
We noticed this bed had a strong chemical smell when we first unpacked it. Due to this off-gassing, itโs best to leave it in a well-ventilated room for at least a day or two before adding any bedding.
Also, it would help to have a friend or a family member assist you in unboxing and placing the bed on your foundation of choice since we found it to be quite heavy.

Helix Sunset FAQs
Does the Helix Sunset mattress need a box spring?
According to Helix, you shouldnโt use a box spring for the Sunset unless you have a bunkie board on top. Instead, the company recommends a slatted base with slates 5 inches apart. They also recommend adjustable bases and platform bed frames.
Is the Helix Sunset organic?
No, the Helix Sunset is not made from organic materials. If youโre after a more eco-friendly mattress, the Helix Birch may be a good option as it has natural Talalay latex, eco-friendly Birch wool, and soft organic cotton.
Why does my Helix mattress smell?
Itโs common for bed-in-a-box mattresses containing synthetic materials to produce a chemical smell when you first open and unwrap them. This is called off-gassing. The odor, although unpleasant, is considered harmless and should fade within a day or two.
What does Helix do with returned mattresses?
When you return a mattress, Helix donates it to charities and housing facilities in your local community. However, this is sometimes not possible if your stateโs laws prohibit donating used mattresses. In this case, Helix sends them over to recycling centers, so they donโt sit in landfills.

Our Verdict
The Helix Sunset is a hybrid mattress with a soft feel and excellent pressure-relieving memory foam.
In our opinion, the Helix Sunset is a good mattress for lightweight and average-weight side and back sleepers. Itโs also good for those who arenโt easily disturbed since it doesnโt have the best motion-isolating capabilities. The softer feel of this mattress could also be great for those with achy joints and muscles, though we think itโs not supportive enough for plus-size people and stomach sleepers.
Our team gave the Helix Sunset mattress an overall score of 4 out of 5.
