Helix Sunset Mattress Review

Materials: Foam and coils

Firmness: 4/10

Warranty: 10 years

Trial Period: 100 nights

Price Range: $500–$1,199

The Mattress Nerd’s Take: The Helix Sunset is a soft, pressure-relieving  hybrid mattress that uses individually wrapped coils and three layers of foam to deliver a plush, yet supportive feel that’s great for side sleepers and those with joint pain. The bed’s layer of individually wrapped metal coils provides excellent edge support and a responsive feel, which works well for combination sleepers who move around often in their sleep.

Priced just under $1,000 for a Queen size, the Helix Sunset is also a wise choice for budget shoppers who still want a high quality bed. But if you’re looking for a more luxurious version of this mattress with the same firmness level, the Helix Sunset Luxe could provide the solution with its quilted pillow top and Tencel cover. Check out our comparison of Helix Luxe mattresses for more details. 

Who is the Helix Sunset Mattress Best For?

Lightweight (< 130 lbs):  4 3 5
Average weight (130 – 230 lbs): 3 2 5
Heavyweight (> 230 lbs):  2 2 4

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Back Sleepers

While back sleeping is the most popular sleep position, back sleepers need a secure and supportive surface that keeps the body from sinking down too far into the bed. The best mattress for back sleepers is no too soft, to provide proper spinal alignment. Because the Helix Sunset is a softer mattress (our team rated it a 4 out of 10 firmness level), it will not be the best mattress for back sleepers, especially those who are heavyweight. The coils in the core of the mattress should be supportive enough for lightweight back sleepers, but even average-weight folks should consider a firmer mattress unless they’re set on a soft, cozy feel. Thankfully, Helix offers a wide lineup of beds to address different sleep styles and weights. The Helix Twilight and the Helix Dawn are the firmest beds, and there’s even a mattress for the plus size, fittingly named the Helix Plus. If you are looking for a more supportive mattress, check out the best mattress for heavy people.

Stomach Sleepers

Like back sleepers, stomach sleepers require a supportive surface that keeps their hips aligned and elevated on the bed. Why is that important? Well, the spine’s natural curve tends to be very slight, so an exacerbated curve caused by improper support could cause pain in the lumbar region (think of how arching your back toward a backbend feels). Because the Helix Sunset is on the softer side of the mattress firmness scale, we don’t think it will work well for lightweight, average-weight or heavyweight stomach sleepers. There’s just not enough support in the Helix Sunset to keep the hips properly elevated for stomach sleepers of any body size. The firmer Helix Dawn is specifically designed for back and stomach sleepers. For other recommendations, see the best mattress for stomach sleepers list.

Side Sleepers

Side sleepers should love the Helix Sunset mattress because its soft construction allows the hips and shoulders to properly sink down into the bed. That cradling around the hips and shoulders is important to ensure lateral spinal alignment. While heavyweight side sleepers might experience the Helix Sunset as a bit softer than smaller body sizes, it should still be a good fit for those plus-size sleepers. Lightweight and average-weight side sleepers will also find pressure relief in the bed’s soft comfort layers.  For other contouring mattresses, see our picks for the best mattress for side sleepers.

Combination Sleepers

The best mattress for combination sleepers allows them to easily switch positions on top of the mattress. When choosing a mattress, it’s also helpful for combination sleepers to think through the sleep positions they sleep in most often. For instance, if you’re a combination sleeper who splits time evenly between your back and your stomach, the Helix Sunset won’t work as well for you. Overall, this bed should appeal to lightweight, average-weight and heavyweight combination sleepers who spend a lot of time on their sides. But it still has a soft and marshmallow-like feel, which means you might not be able to switch positions as quickly or easily as you might wish, depending on your size.

How Does the Helix Sunset Mattress Feel? 

Responsiveness, Bounce and Ease of Movement 

When we tested the Helix Sunset in our mattress lab, the plush comfort layers made it more difficult to move around and maneuver on this mattress than, say, a pillow top mattress. When you get into the bed it’s easy to settle into and feel comfortable, but it’s difficult to switch positions: for instance, from your side to your stomach. It’s also a bit difficult to lift yourself out of the mattress when it’s time to rise in the morning. Overall, the firmer Helix Dusk, Helix Dawn and Helix Twilight models score better on responsiveness. 

How Firm Is This Mattress?

This mattress is rated around a 4 out of 10 on our firmness scale, meaning it’s of the softer mattresses that we test here at Mattress Nerd. While some people (especially heavier folks) want more support than the Helix Sunset offers, others are specifically searching for a soft feel. Side sleepers do especially well with softer mattresses like this one, because it allows for adequate pressure relief around joints like the hips and shoulders. And those struggling with arthritis or other joint pain might benefit from the soft, cradling feel of the Sunset

Does It Sleep Hot? 

We understand the struggle for hot sleepers who just want a cool night of rest: It’s no fun to settle down into a fluffy bed and realize you’re beginning to feel stifled. Unfortunately, that’s the story with the Helix Sunset. It includes a soft and breathable cover, but the bed tends to envelop the body too much to ensure a breezy night of sleep. The individually wrapped coils in this bed offer some breathability, but neither the Memory Plus foam nor Helix Dynamic foam are gel-infused, which means they aren’t great for ultra-hot sleepers. For those of you who can’t seem to get cool, check out our Best Cooling Mattresses.

Is the Helix Sunset Mattress Good For Couples? 

Motion isolation is where this coil and foam mattress stands out from the competition. When two mattress testers tried out the Helix Sunset in our in-house motion transfer test, they almost couldn’t detect another “sleeper” getting in and out of bed. That’s great news for people who sleep with a partner or a pet and awake easily from feeling movement. The cushioning provided by the layers of soft foam means that motion transfer is kept to a minimum. For mattresses that isolate motion well, see the best mattress for couples.

How’s the Edge Support? 

Edge support is a mattress-buying factor that the Helix mattress company has taken into consideration for all of its Helix mattress models, including the Sunset. Each Helix bed comes with reinforced coils on the edges to help provide extra bolstering and support around the perimeter of the bed. During our edge support test, we found that the Sunset’s support layer kept the bed from sagging too much when a tester sat right on the edge. The edge support was even better when one of them “slept” along the perimeter. If your sleep partner stretches out too far and leaves you stranded all the way along the edge of your mattress, the Helix Sunset will make sure you don’t feel unstable in that position. 

Construction: What’s Under the Surface?

The Helix Sunset uses several layers of foam atop its system of individually wrapped coils, making it great for those with joint pain who need a soft and cradling top layer in their mattress. The bed is also good for side sleepers, but it won’t work as well for stomach sleepers and anyone looking for an ultra-firm feel

Layer #1: Cover: Each Helix mattress, including the Helix Sunset, comes with a Helix Soft Touch cover that feels a bit stretchy when you lift it with your hand. It doesn’t feel cool to the touch when you put a hand on it, but this is certainly a breathable, airy cover.

Layer #2: Comfort Layer: The Sunset uses Memory Plus foam in the top comfort layer of the mattress, which gives the top of the bed a soft and supple feeling. This layer is great for pressure relief, especially for side sleepers.

Layer #3: Transition Layer: Right above the innerspring coils, the Helix Sunset uses a transition layer of Helix Dynamic foam. Though Helix uses Dynamic foam in many of its mattresses, the IFD (or “indentation force deflection”) of the foam can vary amongst the hybrid mattresses. The Helix Sunset uses a lower IFD foam to create a softer, more cushion-like feel. 

Layer #4: Coil Layer: The Helix Sunset, like other mattresses in the Helix line, uses a collection of coils in the mattress for support, stability and bounce. Because the coils are individually wrapped, motion transfer is kept at a minimum. If you are looking for a bouncy mattress with coils, check out the best innerspring mattresses.

Layer #5: Base Layer: Helix uses a layer of DuraDense foam at the bottom of the mattress to secure the individually wrapped coils and add some softness to the bottom of the bed. People won’t be able to feel this layer as they sleep, but it offers a bit more durability and loft for the mattress.

How Do the Policies Measure Up? 

Shipping & Unboxing

Helix ships all of its mattresses via FedEx Ground to all 50 states for no charge, and to most Canadian provinces for a $250 charge. After placing your order, you can expect to receive your bed-in-a-box within three to 15 business days. Our team unboxed the Helix Sunset in under two minutes and noticed that it seemed to inflate to its full size almost immediately. There was a slight off-gassing smell, but nothing that would bother most sleepers. 


All Helix mattresses are protected by a 10-year warranty against material and workmanship defects. Helix Luxe models—the more deluxe version of each bed—come with a 15-year warranty. Compared to the rest of the mattress industry, the Helix warranty is relatively standard. Helix covers mattress indentations greater than 1” deep, as well as any manufacturing defects in the mattress cover.

Trial Period & Returns

All Helix mattresses come with a 100-night sleep trial, meaning you can test them out for up to 100 days to see if they’re right for you. You can return the mattress within that period for a full refund. But take note: Customers must try the mattress for 30 days, starting from the date of delivery, before they can initiate a return.


Compare Mattresses

Comparing the Helix Mattresses

Customers looking for a more elevated feel in their Helix mattress can turn to the Helix Luxe line, a collection of sister beds to the standard mattresses that each feature a 2″ taller profile, a Tencel cover and a premium pillow top. The Helix Sunset Luxe feels just as soft as the Helix Sunset, but its Tencel cover offers extra breathability, and the added zoned support bolsters the hips as you sleep. 

Helix Sunset vs. Helix Moonlight

The Helix Moonlight mattress is a soft bed that’s designed for back sleepers and stomach sleepers. Rated at a 3 on our mattress firmness scale (with 10 being the firmest), this bed is for those who know they need support, but aren’t quite ready to forgo classic memory foam softness. 

A cousin to the Helix Sunset in the “soft feel” category, the Helix Moonlight features reinforced steel coils around the perimeter of the bed to aid in edge support. The main difference between the two? While the Sunset is great for side sleepers who want pressure-point relief at the hips and shoulders, the Helix Moonlight offers more body contouring and hip-elevating support.

Helix Moonlight

The Helix Moonlight is one of the softest firmness options available from Helix. Pressure- relieving foam allows sleepers to sink deep into the layers and feel cradled by the mattress.

See our full Helix Moonlight Mattress Review to learn more. 

Helix Sunset vs. Helix Midnight

When you take a rest on the Helix Midnight mattress, it will have a distinctly firmer feel than the Helix Sunset. The Helix Midnight is still good for side sleepers, but we’d recommend it for average-weight to heavyweight side sleepers. Lightweight side sleepers, who tend to feel mattresses as a bit firmer than those with a heavier body, will want to stick with the Sunset. 

The Helix Midnight, the brand’s most popular mattress, is specially designed to promote pressure-point relief, which is great for those struggling with arthritis or a similar condition. Each of these beds are also priced identically.

Helix Midnight

The Helix Midnight provides tailored support and a medium-firmness feel geared specifically for side sleepers. The hybrid construction promotes airflow to keep you cool, while the foam layers provide cradling and support where you need it.

Helix Sunset vs. Helix Plus

Designed specifically for folks who are heavyweight, the Helix Plus mattress is a thick and supportive bed made with three layers of foam and supportive innerspring coils. Lightweight sleepers should go with the Helix Sunset because of its softer feel, but the Helix Plus is good for plus-size sleepers of any sleep position.

The Plus also includes a breathable and cooling Tencel cover that comes in a dark gray color, which sets the Plus apart from the sea of white covers that dominate the Helix line. We also love that the Helix Plus stands 13” high for a lofty, hotel-bed profile. The Helix Sunset, for reference, stands 12” tall.

Helix Plus

The Helix Plus is designed with plus-size or taller individuals in mind. The mattress features extra-dense memory foam that won't lose its shape over time, even with added weight.

Helix vs. Other Brands

Helix Sunset vs. Nectar

While the Helix Sunset is a hybrid mattress made with individually wrapped coils and foam layers, the Nectar mattress is an all-foam bed that includes a top layer of gel memory foam, a middle “transition” layer and a base layer. The Tencel cover and cooling gel foam in the Nectar help it stand out from the competition, but the bed is a bit more expensive than the Helix Sunset. 

Because of the Helix Sunset’s soft feel and thick foam layers, we expect that the all-foam Nectar and the Sunset will perform relatively evenly in motion isolation. But the Helix Sunset’s coil layer allows it to excel in edge support.


The Nectar is an affordable quality mattress with an excellent trial period. It suits all types of sleepers, couples and people who love sleeping on memory foam.

Helix Sunset vs. Casper

Chances are, when you think “bed-in-a-box mattress,” Casper is one of the first brands that comes to mind. This memory foam bed is designed to accommodate all kinds of sleep positions, combining support and pressure relief. 

If you’re dead-set on a hybrid mattress with coils, the Helix Sunset is the obvious option. But if you’re willing to try an all-foam bed, the Casper is priced similarly to the Helix and offers Zoned Support, meaning one foam layer provides more support and firmness to the hips and shoulders.

Casper Original

The original mattress that made the brand famous, the Casper is known for its design that suits all sleep positions. Casper's Zoned Support feature is engineered to support the hips, shoulders and back to keep the spine aligned. At an affordable price point, too, this mattress is hard to beat.

Helix Sunset vs. Nolah

The Nolah Original mattress has a lower profile than the Helix Sunset, standing just 10” tall. It includes cooling AirFoam in the top layer as well as a bouncy transition layer and a 7” tall base layer. While the Helix Sunset is made with a mixture of coils and foam (a “hybrid” bed), the Nolah Original is made completely of foam layers. 

If you’re a stomach or back sleeper looking for support, the Nolah Original mattress will have more to offer than the softer Helix Sunset. But if you’re a side sleeper or someone with aches and pains who wants to be cradled by your mattress, the Helix Sunset is your best bet.

Nolah Original 10"

The Nolah Original 10” mattress is made of three layers of AirFoam and wrapped in a soft, breathable viscose fabric cover that helps moisture evaporate to keep you dry and cool.

Helix Mattress FAQs

Are the materials in Helix mattresses safe?

Helix uses CertiPUR-US certified foams in all of its mattresses, meaning that they don’t include harmful chemicals such as ozone depleters, PBDE or formaldehyde. If you’re especially concerned about finding an eco-friendly mattress, Helix also manufactures the all-organic Birch mattress. 

Do Helix mattresses have an off-gassing period?

During our in-house mattress-testing process, we found that the high-grade materials used in Helix mattresses resulted in very little odor or off-gassing. Any odors you might smell in the new mattress should dissipate within a day, but it’s best to situate a newly opened mattress in a room with plenty of ventilation.

Do Helix mattresses need a foundation?

While a foundation isn’t required for Helix mattresses, it’s advised that sleepers use some type of base system to prevent sagging and to ensure proper support for the mattress. Using an adjustable base or any supportive bed frame will also help you honor the terms of the Helix warranty policy. 

What’s the Bottom Line?

The Helix Sunset mattress is one of the softer mattresses made by Helix and is designed for side sleepers and couples who value motion isolation. We wouldn’t recommend this bed for stomach sleepers who need extra support, but it should work well for people dealing with joint pain or for back sleepers who want a soft sleep surface. Priced competitively, the Helix Sunset is a great deal for those seeking a soft, cozy mattress.
