In the crowded landscape of online mattress brands, Helix Sleep has emerged as a standout for its personalized approach to comfort. With a quiz-based system that matches sleepers to their ideal mattress, Helix offers a range of hybrid beds tailored to different sleep styles. Among these, the Helix Sunset is the softest option in the core lineup, designed with side sleepers and plush comfort lovers in mind.
The 2025 version of the Helix Sunset builds on its reputation with subtle upgrades in materials and cooling options. But how does it perform in real-world use? Is it worth the investment? This comprehensive review explores every aspect of the Helix Sunset—from construction and comfort to durability, pricing, and comparisons—culminating in a final verdict to help you decide if it’s the right fit for your sleep needs.
Construction and Materials
The Helix Sunset is a hybrid mattress, meaning it combines foam layers with a coil support system. This blend offers the contouring comfort of foam with the durability and responsiveness of springs. Let’s break down each layer:
Cover
The standard cover is a soft, breathable knit fabric that feels smooth and cool to the touch. For hot sleepers, Helix offers an upgrade to the GlacioTex Cooling Cover, which uses phase-change materials to actively draw heat away from the body.
Comfort Layer
At the top lies Helix’s proprietary Memory Plus Foam, engineered to provide deep pressure relief. It’s softer than traditional memory foam, allowing for gentle sinkage around the shoulders and hips—key areas for side sleepers.
Transition Layer
Beneath the comfort layer is Helix Dynamic Foam, a latex-like material that adds bounce and responsiveness. This layer prevents the “stuck” feeling often associated with memory foam and makes it easier to change positions during the night.
Support Layer
The core of the mattress features individually wrapped coils that adapt to your body’s shape and movements. These coils are zoned for enhanced support and reinforced around the edges to improve edge support.
Base Layer
A layer of high-density polyfoam provides stability and extends the mattress’s lifespan by supporting the coil system.
This thoughtful construction results in a mattress that’s soft yet supportive, breathable yet cozy, and durable enough to last for years.
Firmness and Feel
Helix rates the Sunset as a “Soft” mattress, and most testers agree it falls around a 3–4 out of 10 on the firmness scale (with 10 being the firmest). The plush top layers allow for deep sinkage, especially around pressure points, while the coil base prevents excessive sagging.
Side Sleepers – This is where the Sunset truly excels. The soft foam cradles the shoulders and hips, reducing tension and promoting spinal alignment. Many users report waking up with less shoulder and hip pain after switching to the Sunset.
Back Sleepers – Lightweight back sleepers (under 130 lbs) may find the Sunset comfortable, but average to heavier individuals might prefer a firmer model like the Helix Midnight or Twilight for better lumbar support.
Stomach Sleepers – The softness of the Sunset may cause hips to sink too deeply, leading to misalignment. Stomach sleepers are better off with a firmer mattress to maintain proper posture.
Combination Sleepers – If you switch positions frequently, the Sunset’s responsive foam and coil system makes movement easy. However, its softness may not provide enough support in all positions.
Cooling and Temperature Regulation
Temperature regulation is a common concern with soft mattresses, especially those with memory foam. The Helix Sunset addresses this in two ways:
- Breathable Coil Base: The open structure of the coils promotes airflow, helping heat dissipate.
- Optional Cooling Cover: The GlacioTex upgrade uses phase-change materials to actively cool the surface.
In testing, the standard Sunset performed moderately well in temperature regulation. With the cooling cover, it competes with some of the best cooling mattresses on the market. Hot sleepers should strongly consider this upgrade.
Motion Isolation and Edge Support
Motion Isolation
Thanks to its memory foam layers, the Sunset absorbs motion effectively. Couples will appreciate the reduced transfer—if your partner tosses and turns, you’re less likely to feel it.
Edge Support
The reinforced coils around the perimeter provide solid edge support. You can sit or sleep near the edge without feeling like you’ll roll off. This is a notable strength for a soft mattress, which often struggles in this area.
Durability and Longevity
Hybrid mattresses tend to last longer than all-foam models, and the Sunset is no exception. With high-quality materials and a sturdy coil base, it’s expected to maintain its shape and support for 7–10 years. The 15-year warranty adds peace of mind and reflects Helix’s confidence in its product.
Users report minimal sagging even after several years of use, and the edge support remains consistent over time. The Sunset’s durability makes it a smart investment for those seeking long-term comfort.
