Helix Sunset Mattress Review

Main Features: Helix Sunset Mattress Review

A great place to start reviewing this soft mattress is with a list of its top features:

• Over 38,000 Verified Customer Reviews
• Soft yet supportive construction
• Designed for side sleepers and restless individuals
• Cooling GlacioTex™ cover upgrade
• Multiple memory foam layers for pressure relief
• 1,000 individually wrapped coils with reinforced edges

Adding a support foundation between the mattress and base is optimal, given that the Helix website says that the frame cannot be used on its own. Helix offers a foundation for below the mattress and a Helix bed frame as reasonably priced add‑ons at checkout. If you already have a base or foundation and are unsure if the Sunset Mattress is compatible, contact the manufacturer to make sure.

A Soft Hybrid Soft Mattress

The Sunset is the softest memory foam mattress in the Helix lineup, as per its website. Online reviewers’ firmness ratings for this mattress range from 2 to 5.5. That makes it medium-soft or soft on the industry-standard mattress firmness scale that ranges from 1-10 (1 being softest and 10 being firmest). 

The slight differences in ratings make sense, given the feel of a mattress varies from one person to another. Several web reviewers describe the sleep surface as plush. A person who primarily wants comfort and pressure relief in a mattress might look for a soft mattress online.

This mattress is a hybrid type, meaning it combines foam with a support system, which in this case is springs. Some people prefer hybrids for offering both comfort and support.

Many Sizes

Selecting the right size of mattress can lead to greater comfort and ensure it fits the bedroom well. Helix offers the Sunset Mattress online in these standard US sizes:

• Twin – 38” x 75”
• Twin XL – 38” x 80”
• Full – 54” x 75”
• Queen – 60” x 80”
• King – 76” x 80”
• Cal King – 72” x 84”
• Short Queen – 60” x 74”
• RV King – 72” x 80”

The mattress is 11.5 inches tall for all sizes. There are the most popular sizes in the US, as well as two that are harder to find online: short queen and RV king. That gives solo sleepers and couples plenty of choices at home and while on the road in RVs.

Helix Sunset Mattress Review of Construction

This mattress has five layers, including the cover. It is assembled in Helix’s Phoenix, Arizona factory, an important detail for those who like to support local. 

There are two cover options:

• Breathe Knit Cover
• GlacioTex™ Cooling Pillow Top

The Breathe Knit Cover is 100% polyester with a breathable design for better airflow, as per Helix’s website. Alternatively, you can upgrade to the quilted GlacioTex™ Cooling Pillow Top. Cool to the touch, it is made of 50/50 polyester-polyurethane.

Below the cover are multiple layers of CertiPUR-US® foam. First is the Copper Gel Memory Foam layer designed for comfort and pressure relief. Next are two layers of Helix Responsive Foam; one to cradle and contour the body and the other for ergonomic support and cushioning. The latter transition layer is a lower IFD (indentation force deflection), indicating softer foam.

Next is a layer of 1,000 individually wrapped coils to cradle the body and limit motion transfer. The reinforced side coils (lengthwise) are designed to improve edge support, which can prevent the uncomfortable feeling of being about to roll off the mattress side.

Finally, the DuraDense Foam base layer made of highly dense polyfoam helps stabilize the layers above it. The durable material may help the mattress keep its shape better.

Pros and Any Limitations: Helix Sunset Mattress Review

Looking at the potential benefits, as well as any drawbacks, of the Sunset Mattress may help you make a more informed decision.

Pressure Relief for Restless and Side Sleepers

The Sunset is designed for side sleepers and those who toss and turn at night, as per Helix’s website. For example, side sleepers put pressure on their hips and shoulders, which can leave these areas sore by morning. This mattress may help side sleepers relieve pressure in these areas for a comfier sleep. 

Restless sleepers are those who shift positions throughout the night. They are also called combination sleepers. There are positive reviews online for the Sunset from those with this sleep style. However, the mattress is not specifically designed for strictly back or stomach sleepers; they may not find it comfortable or supportive enough. 

With that said, we appreciate Helix tailoring the Sunset’s features to include side sleepers, the most common sleep position in the US. While larger-framed people may want a firmer mattress to get enough support, this mattress offers potential benefits for those of average or light body weight. 

Support and Spinal Alignment

Some web reviewers praise the Helix Sunset Mattress’s soft yet supportive construction. In addition to helping alleviate pressure in the hips and shoulders for certain people, the memory foam layers contour the body’s curves. 

That encourages proper spinal alignment. This design is important for restless and side sleepers as it can relax the body, potentially leading to better sleep quality. Plus, the individually wrapped coils move independently, helping some people feel supported.

Breathable and Cooling

For those wanting a fresher sleep, the Breathe Knit Cover has a high airflow design that likely appeals. It may help with temperature regulation, potentially leading to better sleep quality. As for the GlacioTex™ Cooling Pillow Top upgrade, it feels cool upon contact with the body and whisks heat away from the body, which may help those who overheat get a cooler sleep.

Responsive and Low Motion Transfer

A responsive mattress is one that adjusts and conforms to the body well. The two Helix Responsive Foam layers in the Sunset Mattress offer this benefit, which can help sleepers change positions more easily. Furthermore, the individually wrapped coils respond individually to movement, which may improve the responsive feel. Some online reviewers explain that moving around on the Sunset is easy.

A related mattress quality is motion transfer, or the likelihood of feeling your partner move or get up during the night, which could wake you up. A responsive mattress generally has lower motion transfer, which is good news if you or your partner regularly toss and turn during the night. These features mean the Sunset Mattress may suit couples and combination sleepers well.

Safety and Eco‑Friendly Certifications

This mattress is CertiPUR-US® certified, meaning the foam is free of heavy metals like mercury or lead. The certification means the foam meets strict environmental and health safety standards.

The CertiPUR-US® foams are low in VOCs (Volatile Organic Compounds) for less off-gassing. While the slight odor when unboxing a mattress in a box containing foam is typically harmless, it can be uncomfortable for some people. Opening the bedroom windows to improve air circulation helps some people. The smell typically disappears within a week, as per Helix’s website. 

Furthermore, the Sunset Mattress has been tested and certified GREENGUARD® Gold, meaning it meets specific chemical emission standards. That is likely important for those looking to improve indoor air quality at home.

Finally, Helix’s Sunset Mattress is fiberglass free. That can help avoid skin irritation and other issues that sometimes accompany sleeping on a surface containing fiberglass.  

Affordable Mattress in a Box

The Helix Sunset conveniently ships free to your door, provided you live in the contiguous US. There is a small shipping fee to Alaska, Hawaii, and Canada. There are also in-home setup and removal services to choose from at checkout.

The mattress in a box design keeps the hybrid affordable. No special shipping service is needed, and there is no middleman, so the company passes the cost-savings onto consumers like you with a reasonable price tag. Financing through Affirm is available at the Helix website for those who prefer this option.

More to Know about Helix’s Sunset

Reinforced Edges

The Helix Sunset Mattress has reinforced side coils (lengthwise). The two 2-sided edge support can help prevent edge sagging and contribute to better overall mattress stability. Stronger edges also make for a bigger usable sleep surface, as you’re less likely to feel like you’re going to roll off the edge.

Sleep Trial

A 100-night sleep trial comes with your Sunset Mattress. That gives you several nights to try the mattress at home. In the unlikely event you decide it is not a good fit within that period, Helix offers free returns on this mattress (meeting the respective policy guidelines, of course).

Warranty

Helix includes a generous limited lifetime warranty with the Sunset Mattress. That covers manufacturing defects, based on the warranty policy, which we encourage you to read to better understand what is included, excluded, and other information. This long protection shows confidence in the mattress construction.

Concluding the Helix Sunset Mattress Review

Knowing details about the mattress materials and how it is made helps you decide if it is likely to suit your bedroom. The 11.5-inch tall mattress has many features that cater to common needs of those who regularly side sleep or toss and turn at night. 

For example, the multiple memory foam layers offer pressure relief and body contouring, especially for side sleepers’ shoulders and hips that have direct contact with the mattress. As for the individually wrapped coils, they contribute to a more responsive mattress with low motion transfer that many couples and combination sleepers can appreciate. The soft support may provide a better rest.

While plus-size sleepers may need a firmer mattress, the soft support of the Sunset can be appropriate for several lightweight and average-weight individuals who are side or combination sleepers. With its lifetime warranty, sleep trial, and other features, the Helix Sunset is a high-value soft hybrid mattress, in our opinion.
