The Helix Sunset is Helix's softest mattress and the most pressure-relieving option in the entire Core lineup. Built around a 2" gel-infused memory foam comfort layer and a pocketed coil support core, it delivers a genuinely soft, cradling feel that's purpose-built for side sleepers who want their shoulders and hips cushioned deeply without having to step up to a Luxe or Elite model. At 11.5" tall with a TENCEL™ cover, it's a clean, well-priced entry point into the Helix lineup.

The trade-offs common to all Core models apply here too: support and edge support are modest at 5.0, which reflects the entry-level coil system and thinner foam base relative to the Luxe and Elite versions. For lightweight side sleepers who want a genuinely soft hybrid feel and don't need the deeper construction of the upper tiers, the Helix Sunset is a focused and effective recommendation.

MEET THE HELIX SUNSET MATTRESS

Firmness, Construction, and Performance

At The Drift, we take mattresses (and your sleep) seriously. That starts with what your bed is made of and how that translates to its feel and durability. Let's dive in.

Feel & Firmness

  • Firmness Level: The Helix Sunset is Helix's softest mattress, sitting at around 3 to 3.5 out of 10 on the firmness scale. This is a genuinely soft mattress -- not just a mild plush, but a deliberate soft feel designed to allow meaningful sinkage at the shoulders and hips.
  • Feel Description: The 2" gel-infused memory foam at the surface gives the Helix Sunset a slow, cradling quality that wraps around the body's contours gradually. The Dynamic Foam transition layer below it prevents you from sinking all the way through to the coils, while the pocketed coil base provides lift and structure from below. The overall experience is soft and cushioned at the surface with a supportive floor below -- the classic memory foam hybrid feel at its softest.
  • Our Take: The Helix Sunset delivers what it promises: the softest feel in the Core lineup with meaningful pressure relief for side sleepers at lighter body weights. The ratings reflect its honest strengths and limitations. Pressure relief at 7.0 is the highest in the Core tier. Support and edge support at 5.0 are the most modest scores -- a natural consequence of the entry-level construction and soft surface that allows more sinkage than a firmer mattress. For lightweight side sleepers who don't need premium construction, this is a focused and well-executed option. For average or heavier body weights, the Sunset Luxe or Sunset Elite will deliver a more complete experience..

Construction & Materials

Height: 11.5"

Design: Entry-level soft hybrid with gel-infused memory foam comfort layer. TENCEL™ cover standard. Optional GlacioTex and ErgoAlign upgrades available. Limited Lifetime Warranty. Assembled in the USA.

Layer Breakdown:

  1. TENCEL™ Cover (standard) / GlacioTex Cooling Cover (upgrade): The standard TENCEL™ cover is naturally breathable and soft. The GlacioTex upgrade replaces it with a 50/50 polyester and polyethylene blend featuring high thermal conductivity fibers for a cool-to-the-touch surface feel.
  2. ErgoAlign Layer (upgrade): When added, this zoned top layer places a segment of ultra-dense foam under the midsection to provide targeted lumbar and pressure support while allowing the shoulders and lower body to follow the natural contours of the mattress.
  3. Gel-Infused Memory Foam Comfort Layer (2"): The defining layer of the Helix Sunset. Low-density gel-infused memory foam provides the soft, cradling feel the mattress is known for. The gel infusion moderates surface heat buildup while the foam conforms gradually to the body's shape.
  4. Helix Dynamic Foam Transition Layer: A responsive polyfoam layer that sits between the memory foam and the coil core, preventing sleepers from bottoming out into the springs and providing a balanced bridge between the soft surface and the structured support below.
  5. Pocketed Coil Support Core: Individually wrapped coils provide deep compression support, promote airflow through the mattress interior, and contribute to the mattress's motion isolation and structural foundation.
  6. Base Foam: Foundational layer that stabilizes the coil system and supports the mattress's long-term durability.

Why It Matters: The Helix Sunset's memory foam comfort layer is what separates it from the Moonlight Core at the same softness level. Memory foam contours more slowly and deeply than Dynamic Foam, which makes it better suited to side sleepers who need time for the foam to wrap around the shoulder and hip rather than the quicker rebound of a more responsive material. The gel infusion addresses the most common criticism of memory foam -- heat retention -- keeping the surface temperature more neutral without relying on a specialty cover. TENCEL™ is a naturally breathable fiber that adds further surface breathability.

Performance Breakdown

CategoryOur RatingSummary
Pressure Relief7 / 10The strongest score in the Core lineup and the primary strength of the Helix Sunset. The 2" gel-infused memory foam delivers genuine cushioning at the shoulders and hips for lightweight side sleepers. The soft feel allows meaningful sinkage that distributes pressure across a wide surface area.
Cooling7 / 10Good for a Core model. The gel-infused memory foam moderates surface heat, and the pocketed coil base promotes airflow through the support core. The GlacioTex cover upgrade meaningfully improves this score for hot sleepers and is worth considering at this tier.
Support5 / 10Below average relative to the broader lineup. The soft surface and entry-level coil system provide adequate support for lightweight sleepers, but average or heavier body weights will notice insufficient pushback at the lumbar region. The Sunset Luxe or Sunset Elite are better structural fits for those body weights.
Motion Isolation6 / 10Above average for a Core model. The memory foam comfort layer absorbs partner movement more effectively than the Dynamic Foam in the Moonlight Core. A decent option for couples at this price tier.
Edge Support5 / 10Below average. Without perimeter coil reinforcement, the edges of the Helix Sunset compress noticeably under body weight. Sitting on the edge or sleeping near the side of the mattress reveals meaningful compression. The Luxe and Elite tiers offer meaningfully better edge support.
Ease of Movement6 / 10Average. The memory foam's slow response makes repositioning more effortful than a Dynamic Foam or latex model. Combination sleepers who move frequently during the night may find the Moonlight Core's more responsive surface a better fit.

Sleep Position Ratings

The primary recommendation for this mattress. Lightweight side sleepers under 130 lbs will find the soft memory foam delivers the shoulder and hip pressure relief they need. Average-weight side sleepers between 130 and 200 lbs may find the Midnight Core's medium feel a better structural fit.

Limited. The soft surface allows too much hip sink for most back sleepers, disrupting spinal alignment. Lightweight back sleepers under 130 lbs may find it workable, but the Moonlight or Dusk Core are more appropriate starting points for back sleeping.

Not recommended. The soft feel and low support score create conditions for excessive hip sink and lumbar misalignment for stomach sleepers at any body weight.

Decent for those who primarily side sleep and shift occasionally. The lower ease-of-movement score means frequent position changes are more effortful than on a more responsive model. Combination sleepers who move regularly should compare the Moonlight Core in the showroom.

Final Verdict

The Helix Sunset is Helix's softest and most pressure-relieving Core model -- a well-focused entry-level hybrid for lightweight side sleepers who want a genuinely soft memory foam feel without stepping up to the Luxe or Elite tier. Pressure relief leads at 7.0. The trade-offs in support and edge support are real and worth understanding before buying. For the right sleeper at the right body weight, this is a targeted and effective recommendation.

Best For

  • Lightweight side sleepers under 150 lbs who want a genuinely soft memory foam hybrid
  • Sleepers who prefer a slow, cradling feel over a responsive surface
  • Budget-conscious shoppers who want Helix's softest feel at an accessible price
  • Couples at lighter body weights where motion isolation is a moderate priority

Not Ideal For

  • Average or heavier body weights who need more structural support than a 5.0 support score provides
  • Back and stomach sleepers who need lumbar support and hip resistance
  • Combination sleepers who move frequently -- the memory foam's slow response makes repositioning effortful
  • Sleepers who need strong edge support for full mattress utilization
  • Hot sleepers without the GlacioTex upgrade -- the memory foam base retains heat without it
