The Helix Twilight is Helix's firm memory foam hybrid and the firmest side-sleeper-oriented model in the standard lineup. Sitting at around 7 out of 10 on the firmness scale with a 2" gel-infused memory foam comfort layer, it delivers a structured, supportive surface that cushions without allowing significant sinkage -- an ideal combination for heavier side sleepers who find softer mattresses allow too much hip drop, or average-weight sleepers who simply prefer a firm feel beneath them at night.

At 11.5" tall with a TENCEL™ cover, it's the firm counterpart to the Sunset's softness -- both built around the same memory foam approach but calibrated to opposite ends of the firmness range.

MEET THE HELIX TWILIGHT 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.
Helix-Twilight-Mattress-Detail at The Drift

Feel & Firmness

  • Firmness Level: The Helix Twilight sits at around 7 out of 10 -- firm. The surface resists sinkage more than the Midnight, but the memory foam still provides a degree of body contouring that differentiates it from purely foam-free firm mattresses.
  • Feel Description: The 2" gel-infused memory foam at a firmer density gives the Twilight a surface that feels structured and resistant first, with a subtle contouring quality beneath. You won't sink meaningfully into this mattress -- instead, you'll feel the foam adjust slightly around your body's contact points while the overall surface maintains its firmness. The pocketed coil core below adds further structural depth. The overall character is firm and stable with a thin layer of memory foam refinement at the surface.
  • Our Take: The Twilight's ratings reflect the practical reality of a firm memory foam hybrid at the entry level. Pressure relief drops to 5.5 compared to the Midnight's 6.5 -- a natural consequence of the firmer surface allowing less sinkage around pressure points. Support improves to 6.0, edge support improves to 6.0, and ease of movement improves to 6.5 -- all meaningful gains that reflect the firmer construction's structural advantages. For heavier side sleepers or firm-preference sleepers, these are the right trade-offs. For anyone who's unsure whether firm is right for them, testing this alongside the Midnight and the Dawn in our showroom is the most efficient way to find out.

Construction & Materials

Height: 11.5"

Design: Entry-level firm memory foam hybrid. TENCELâ„¢ cover standard. Optional GlacioTex and ErgoAlign upgrades available.

Layer Breakdown:

  1. TENCELâ„¢ Cover (standard) / GlacioTex Cooling Cover (upgrade): The standard TENCELâ„¢ cover provides natural breathability. The GlacioTex upgrade brings high thermal conductivity fibers for a cool-to-the-touch surface that addresses the memory foam's heat retention tendencies.
  2. ErgoAlign Layer (upgrade): When added, a zoned top layer provides ultra-dense foam under the midsection for targeted lumbar support while following natural body contours at the shoulders and lower body.
  3. Gel-Infused Memory Foam Comfort Layer (2"): Firm-density memory foam that provides structured surface resistance with a thin layer of contouring beneath. The gel infusion moderates surface heat without softening the feel. At this firmness level, the memory foam adds refinement to the firm surface rather than significant sinkage.
  4. Helix Dynamic Foam Transition Layer: A responsive polyfoam layer between the memory foam and the coil core that provides even weight distribution and contributes to the mattress's balanced support profile.
  5. Pocketed Coil Support Core: Individually wrapped coils provide deep compression support and the structural foundation of the Twilight's firm feel. Improved support over the softer models comes primarily from the firmer interaction between the coil system and the denser memory foam above it.
  6. Base Foam: Foundational support layer for long-term structural integrity.

Why It Matters: The Twilight uses the same construction approach as the Sunset and Midnight -- memory foam over Dynamic Foam over pocketed coils -- but the higher foam density creates a meaningfully different functional profile. Firmer memory foam resists compression more strongly, which translates to better spinal alignment for heavier body weights in side sleeping and for back sleepers across a broader weight range. The improved support and edge support scores both reflect this. The trade-off is less pressure relief at the surface -- a known and expected consequence of firmer construction.

Our Ratings & Advice

We've tested over 1,000 mattresses in the last 10 years and helped serve better sleep to over 1 million shoppers. Our ratings are born out of lab-based testing and real world evaluations.

Performance Breakdown

CategoryOur RatingSummary
Pressure Relief5.5 / 10Below average relative to the broader lineup. The firm memory foam surface limits sinkage at the shoulders and hips, which reduces the deep pressure contouring that softer models provide. Heavier side sleepers benefit from the hip alignment advantage; lighter side sleepers may find it too firm.
Cooling7 / 10Good. Gel infusion moderates surface heat and the coil core promotes airflow. The firm density means sleepers don't sink as deeply into the foam, which reduces heat accumulation compared to softer memory foam models. The GlacioTex upgrade is still worth considering for consistent hot sleepers.
Support6 / 10Good for the standard tier. The firmer construction provides better lumbar reinforcement than the Sunset or Midnight, and supports a wider range of body weights in back and side sleeping positions. Still below what the Luxe tier's zoned coil system provides for heavier sleepers.
Motion Isolation6 / 10Average. The memory foam comfort layer provides a degree of motion absorption, consistent with the other memory foam models in the standard lineup.
Edge Support6 / 10Decent -- a modest improvement over the softer standard models. The firmer comfort layers compress less at the perimeter, providing slightly better edge stability without perimeter coil reinforcement.
Ease of Movement6.5 / 10The best ease-of-movement score among the memory foam standard models. Firmer memory foam recovers more quickly than softer variants, making repositioning more natural than on the Sunset or Midnight.

Sleep Position Ratings

Good for heavier side sleepers above 200 lbs who find medium mattresses allow too much hip drop. The firm surface keeps the hips closer to the surface for better spinal alignment at heavier body weights. Lighter side sleepers under 150 lbs will likely find the Twilight too firm -- the Midnight or Sunset are better fits.

Very good at average body weights. The firm surface and improved support score make the Twilight a solid back-sleeping option for sleepers who prefer a firm feel. The ErgoAlign upgrade adds meaningful lumbar reinforcement on top of the baseline construction.

Good for average-weight stomach sleepers. The firm surface provides better hip resistance and spinal alignment than the Midnight or Sunset. Heavier stomach sleepers should also test the Dawn for a Dynamic Foam alternative at similar firmness.

Good. The improved ease-of-movement score makes repositioning more natural than the softer memory foam models, which is a meaningful advantage for restless sleepers.

Final Verdict

The Helix Twilight is Helix's firm memory foam option in the standard lineup -- a focused recommendation for heavier side sleepers and average-weight back and stomach sleepers who want a firm surface with a thin layer of memory foam refinement.

Support, edge support, and ease of movement are all improved over the softer standard models. Pressure relief is the honest trade-off. For the right sleeper at the right body weight, this is a well-executed firm hybrid that delivers on its specific purpose.

Best For

  • ✓ Heavier side sleepers above 200 lbs who need hip alignment support on a firm surface
  • ✓ Average-weight back sleepers who prefer a firm feel with some memory foam contouring
  • ✓ Average-weight stomach sleepers who need more surface resistance than a medium mattress provides
  • ✓ Firm-preference sleepers who want memory foam's contouring quality in a firm package

Not Ideal For

  • ✗ Lightweight side sleepers under 150 lbs -- the firm surface provides insufficient pressure relief at lighter body weights
  • ✗ Sleepers who want any significant contouring depth
  • ✗ Those who need the strongest possible lumbar support -- the Twilight Luxe's zoned coils are a meaningful step up
  • ✗ Hot sleepers without the GlacioTex upgrade
