The Helix Sunset mattress is a plush, soft hybrid bed, great for side sleepers who enjoy the sinking feeling of foam. Helix allows you to tailor your mattress to your specific sleep experience, so if Sunset isn’t the mattress for you, there are 12 other beds to choose from.

Who Is the Sunset Mattress Best for?

Sunset is best for: Sunset may not be best for:
  • People with back pain
  • Side sleepers who like to sink into their mattress
  • Combination sleepers
  • Those who like a softer feel

Helix Sunset Highlights

Helix crafts mattresses tailored to every body shape and sleeping position. The Helix Sunset mattress is their softest bed, with a plush feel perfect for anyone who finds most mattresses too firm. In this review, we’ll share how the Sunset performed during our in-house testing, its pros and cons, price point, and more so you can determine if it’s the best mattress for you.  

What We Like The Helix Sunset Mattress:

  • The Sunset is the softest Helix mattress, delivering a cloud-like feel ideal for side sleepers
  • Sunset offers good alignment no matter what sleeping position you end up in, earning it an 8.5/10 in our lab test.
  • If you find the Sunset too soft or too firm, Helix will send you a free topper to help you get the best night’s sleep.

Pros and Cons

✅ Pros

  • Cooling: Helix Sunset features a cooling mattress cover optimized for breathability and a system of pocketed coils, creating great airflow.
  • Durability: Thanks to the thick foam layers and sturdy coils, this bed should last you for years to come.
  • Spinal Alignment: This bed provides a nearly straight spine for side sleepers and a decently straight spine for stomach sleepers, helping you wake up without back pain from your mattress.

❌ Cons

  • Motion Transfer: Motion isolation is not one of the Helix Sunset’s strengths. Our sleep testers felt the most movement when their sleep partner got in and out of bed versus when they were tossing and turning.
  • Edge Support: The plush top layers of the Sunset mattress are comfortable, but they don’t provide great edge support.

Edge Support

For those who like to sit on the edge of their bed or use every inch of their mattress, it’s important to find one with great support. When our testers sat on the edge of the bed to put their shoes on there was a significant dip and they felt like they were moving forward. If this category is important to you, consider a firmer mattress like the Helix Midnight, which scored a 9/10 for edge support.

Spinal Alignment

Having a mattress that gives you good spine alignment helps with back pain in the morning because it offers you good posture at night. We looked at spinal alignment while side and back sleeping on the Helix Sunset mattress.

We saw average alignment when we lay on our stomachs. Our hips didn’t sink deep enough for a perfectly flat back, but we got pretty close.

On our sides, it got even better. Our hips and shoulders sunk into the mattress just enough to create a line that was almost perfectly straight. The only thing that stopped us was that our hips sank slightly deepers than our shoulders.

Pressure Relief

We test pressure relief using a heat map in our lab. The coolers colors, such as blue and green, indicate little to no pressure. Warmer colors, like yellow and red, indicate areas of higher pressure. 

Our male and female tester lay on their back, side, and stomach to see how the Sunset dealt with pressure on each.

Both of our testers saw great pressure relief on their back and stomachs.

However, the issue came in when they lay on their sides. Most of the pressure was concentrated on the shoulders and chest. The hips saw decent relief. This means side sleepers who suffer from shoulder pain should probably check out a different Helix mattress.


If you find yourself changing positions often at night, responsiveness is a major feature to look for in your mattress. When we lay on the Sunset mattress to change positions, we noticed that it was very easy to get comfortable quickly in each position.

However, we also noticed that it was difficult to transfer from stomach to side because of the plush foam on top of the mattress.

Overall, we gave Sunset an 8.5/10 for this area.

Product Details

The Helix Sunset is a soft mattress, with a firmness level that falls between a 2–3 on the 1–10 firmness scale. It’s one of the softest hybrid mattresses that you’ll find.


Is It Good for Your Sleeping Position?

The Helix Sunset works for most sleeping positions. Here’s what we think:

  • Side sleepers with shoulder pain would not be best for this mattress, but it works well for most side sleepers thanks to its spinal alignment and pressure relief in your hips. If you have shoulder pain, check out our other recommendations for the best mattress for side sleepers.
  • Back sleepers and stomach sleepers typically don’t mesh well with plush mattresses, but Helix Sunset offers enough support to keep their spines in line. If you’re a heavier sleeper, you may want to look at some of our other top mattresses for stomach sleepers picks and back sleeper mattresses.
  • Most combination sleepers will enjoy the responsiveness level of the Sunset—just not if you’re a side/stomach combo sleeper. If you are, look at our other recommendations for the best mattresses for combo sleepers.

How Good Is It for Cooling?

We found the Helix Sunset to offer decent temperature regulation. It has a breathable cover paired with innerspring coils. These two airflow factors keep your body heat from getting too trapped in the foam. However, it is not the world’s coolest mattress. The cooling factors are about average.

Body Type Support

Helix mattresses are designed to support people who weigh up to 500 lbs. However, heavier people find mattresses softer than lighter people. Because the Sunset mattress has an ultra-plush feel, it will be too soft for most plus-size people. If you weigh more than 230 lb, you’re likely to experience sagging on a mattress this soft.  

Compatible Bed Frames

The Sunset needs a firm and sturdy base for optimal comfort and longevity. Good options include slatted bases with slats no more than 5″ apart, adjustable bases, and platform bed frames. Helix does not recommend using a box spring unless you use a bunkie board on top for added support.

A Look Inside

The Sunset is a four-layer hybrid mattress with a plush feel thanks to contouring foam layers. Let’s take a closer look at how each layer influences the feel of the bed.

  1. Helix Soft Touch Design Mattress Cover: A soft cover that supports optimal breathability for a cool sleeping surface. 
  2. Memory Plus Foam Comfort Layer: A top layer of ultra-soft memory foam creates a cloud-like feel that generously cushions pressure points
  3. Helix Dynamic Foam Transition Layer: A soft polyfoam with a low IFD for extra cushioning
  4. Pocketed Coil Support Layer: A supportive layer of individually-encased coils for responsiveness and ergonomic support
  5. DuraDense Foam: A base layer of high-density polyfoam absorbs motion and boosts durability.

Is It Easy to Set Up?

Sunset comes in a rectangular box that is about four feet tall. It took us about a minute and a half to unbox and set up the Helix Sunset. The coils make it pretty heavy, so we recommend tapping in a partner to help you out. The mattress off-gassing was pretty average and went away in a few hours.

Should You Buy the Sunset Mattress?

Now it’s time to figure out if the Helix Sunset is the bed you want to buy. Let’s review who we think would (and wouldn’t) love the Sunset mattress.

You will probably love the Sunset if…

  • You are a person who enjoys sinking into the mattress.
  • You suffer from back pain.
  • You enjoy the feel of a traditional mattress with coils.

You should keep shopping if…

  • You prefer sleeping on top of the mattress.
  • You are a plus-sized sleeper.
  • You prefer the feel of a memory foam mattress.

If you fall into the “keep shopping category,” we recommend the Layla mattress. Helix also offers the Sunset mattress in a luxe model, which includes an enhanced support and advanced comfort features.

Helix Sunset Mattress Comparisons

Helix Sunset vs Other Hybrid Mattresses

The Helix Sunset stands out from the average hybrid mattress thanks to two features: its price and its softness. The Sunset is one of the most affordable luxury hybrid beds that we’ve seen, even when compared to other bed-in-a-box mattresses. As for its feel, the Sunset is incredibly plush while still being supportive enough for most people. There are few hybrid mattresses that are as soft as the Sunset

Helix Sunset vs Other Helix Mattresses

Helix manufactures two mattress lines and one organic mattress. Here’s how the Sunset compares to Helix’s other beds. 

The Sunset vs the Standard Helix Mattress Collection

Helix’s budget-friendly mattress line consists of seven hybrid mattresses designed for different sleeping positions, body types, and firmness preferences. Each of these mattresses is 12″ thick (other than the Plus) and contains a support layer of pocketed coils. The top two layers are made from a variety of memory foams and polyurethane foams with different densities and feels crafted for specific sleepers. 

Take a look at how the Sunset stacks up when compared to the other standard Helix beds. 

Helix Sunset vs. Helix Midnight

Criteria Helix Sunset Helix Midnight
Mattress Advisor Score 8.4/10 8.7/10
Firmness Soft (3/10) Firm (7/10)
Material Hybrid Hybrid
Who’s It Best For?
  • Side sleepers
  • People who like an ultra-soft mattress
  • Hot sleepers
  • Heavy people
  • Couples
  • Back sleepers

The Helix Sunset is Helix’s softest mattress option. It feels much cushier than the Helix Midnight, which has a firmer feel. That makes the Sunset a better option for side sleepers who like to cuddle up in bed at night. The Sunset is also a good choice for sleepers looking for a soft mattress that won’t wear out too quickly. A lot of soft mattresses lack support or wear thin fast, but the well-made sunset should hold up just as well as Helix’s other mattress offerings.

The firmer Helix Midnight is a better choice for back sleepers. It’s also a better choice for couples and heavy people thanks to its firmer edge support. These folks will be able to spread out over the entire sleep surface, which will make the Midnight feel roomier than the Sunset.

Helix Sunset vs. Helix Moonlight

Criteria Helix Sunset Helix Moonlight
Mattress Advisor Score 8.4/10 8.5/10
Firmness Soft (3/10) Soft (3/10)
Material Hybrid Hybrid
Who’s It Best For?
  • Side sleepers
  • Sleepers with back pain
  • Hot sleepers
  • Side sleepers
  • Combination sleepers
  • Back sleepers

The Sunset and Moonlight are Helix’s two softest mattress options. However, the Helix Moonlight feels just a little firmer and more responsive than the Sunset. That makes it a better choice for combination sleepers who want to feel more “on” than “in” their mattresses. The Moonlight is an especially good choice for combination sleepers who spend part of the night on their sides. They’ll get the cushioning they need at the hips and shoulders, but won’t have trouble rolling over at night.

The softer Sunset is a better option for side sleepers who want the ultimate amount of cushioning. It offers more sinkage and a plusher feel than the Moonlight. The Sunset is also a better pick for sleepers who prefer to feel cuddled “in” their mattresses. All in all, both beds are great options for sleepers who like a soft feel but still want a supportive, durable mattress.

Check out our full Helix Moonlight mattress review.

Sunset vs Dusk

 The Helix Dusk is firmer and has a more balanced foam feel while the Sunset is softer with a plush cradling surface. The Dusk works better for back and stomach sleepers and the Sunset for those who sleep on their sides. 

Sunset vs Twilight

The Helix Twilight is one of few firm beds created for side sleepers, while the Sunset is one of the softest mattresses around. The added support of the Twilight is great for plus-size sleepers while the Sunset’s marshmallow-y surface works well for people who weigh less than 130 lbs. 

Sunset vs Dawn:

The Helix Dawn is a firm bed with a surface that makes you feel like you’re sleeping “on” the bed, while the Sunset is a plush mattress that allows the body to comfortably sink in. The Sunset is perfect for soft mattress lovers and the Dawn for firm bed aficionados. 

Sunset vs Plus

The Helix Plus, formerly the Nightfall, was created for plus-size sleepers. It boasts an additional layer of high-density memory foam for exceptional support and pressure relief. The Plus has a medium firmness while the Sunset is soft. The Sunset is a better fit for lightweight people and the Plus for plus-size individuals.

The Sunset vs Helix LUXE Mattress Collection 

Every one of the original Helix mattresses (with the exception of the Helix Plus) outlined above comes in a more luxurious option in the Helix LUXE mattress collection. For instance, the Sunset also comes in the Sunset LUXE, with the LUXE providing a more lavish sleeping experience. 

Here’s what makes the Helix LUXE models more luxurious. 

  • Tencel Mattress Cover: All-natural Tencel fibers are woven together for an even softer, cooler mattress cover.
  • Premium Pillow Top: The LUXE mattresses each have a quilted pillow top that brings the feel of a 5-star hotel mattress to your bedroom. 
  • Additional Comfort Layer: One more layer of foam atop the innerspring support core adds even more contouring
  • Zoned Lumbar Support: The innerspring coil layer of the LUXE mattresses is zoned, meaning there are more supportive springs under the lumbar region of the body and softer springs at the shoulders. Zoned coils create balanced support and cushion from head-to-toe, providing exceptional pain relief and spinal alignment. 
  • Extra-Sturdy Edges: The reinforced perimeter is even stronger in the LUXE mattresses

The Sunset vs the Birch

The Birch by Helix is an eco-friendly mattress made from natural and organic materials. Made from cotton, wool, latex, and steel, the Birch is a medium-firm mattress with a balanced feel. The Sunset is made from memory foam, polyfoam, and coils for a plush mattress with a deep cradling feel. The Sunset is much softer than the Birch, and it’s also more affordable.
