Helix Sleep has become a go-to brand for sleepers seeking personalized comfort through its hybrid mattress lineup. Among its core models, the Helix Dusk stands out as a medium-feel mattress designed for back and combination sleepers who want a balance of support and responsiveness. Unlike the memory foam-heavy Midnight or the ultra-soft Sunset, the Dusk offers a more buoyant feel with targeted support—ideal for those who dislike the “sinking” sensation of traditional memory foam.
In this comprehensive 2025 review, we’ll explore the Helix Dusk’s construction, firmness, cooling performance, motion isolation, durability, and value. Whether you’re a back sleeper, a restless combo sleeper, or someone who prefers a more responsive mattress, the Dusk might be your perfect match.
Construction and Materials
The Helix Dusk is a hybrid mattress, combining foam layers with a coil support system to deliver bounce, breathability, and long-term durability. Here’s a breakdown of its layers:
Cover
The standard cover is a breathable knit fabric that feels soft and cool. For hot sleepers, Helix offers an upgrade to the GlacioTex Cooling Cover, which uses phase-change materials to regulate temperature and wick away heat.
Comfort Layer
At the top lies Helix Dynamic Foam, a latex-like material that provides a responsive, springy feel. It contours gently to the body without trapping heat or causing a “stuck” sensation.
Transition Layer
Beneath the comfort layer is High-Grade Polyfoam, which adds support and helps maintain spinal alignment. This layer ensures a smooth transition into the coil base.
Support Layer
The core features individually wrapped coils that respond to movement and provide zoned support. Reinforced edges improve edge support and durability.
Base Layer
A layer of high-density polyfoam stabilizes the mattress and supports the coil system.
This thoughtful construction results in a mattress that’s medium-firm, breathable, and responsive—ideal for back and combination sleepers.
Firmness and Feel
Helix rates the Dusk as a medium mattress, and most testers place it around a 6 out of 10 on the firmness scale. It offers a balanced surface with gentle contouring and a buoyant feel.
Back Sleepers – The Dusk is especially popular among back sleepers. The responsive foam and zoned coils support the lumbar region and maintain spinal alignment without excessive sinkage.
Side Sleepers – While not as plush as the Sunset or Moonlight, the Dusk still provides adequate pressure relief for side sleepers who prefer a firmer feel.
Stomach Sleepers – Lightweight stomach sleepers may find the Dusk comfortable, but heavier individuals might prefer a firmer model like the Helix Twilight.
Combination Sleepers – The Dusk’s responsive design makes it easy to switch positions. It’s a great choice for those who move around during the night and want a mattress that adapts quickly.
Cooling and Temperature Regulation
Hybrid mattresses tend to sleep cooler than all-foam models, and the Dusk is no exception.
- Breathable Coil Base: Promotes airflow and prevents heat buildup.
- Optional Cooling Cover: The GlacioTex upgrade actively cools the surface.
In testing, the Dusk performed well in temperature regulation. With the cooling cover, it’s a solid choice for hot sleepers who prefer a medium-firm mattress.
Motion Isolation and Edge Support
Motion Isolation
Despite its coil base, the Dusk offers solid motion isolation. The foam layers absorb movement, making it suitable for couples.
Edge Support
Reinforced coils around the perimeter provide strong edge support. You can sit or sleep near the edge without feeling unstable.
Durability and Longevity
The Helix Dusk is built to last. With high-quality materials and a sturdy coil system, it’s expected to maintain its shape and support for 7–10 years. The 15-year warranty adds peace of mind.
Users report minimal sagging and consistent performance over time. The edge support and responsiveness remain strong even after years of use.
