Medium hybrid for back and stomach sleepers
See where Dusk fits across Core, Luxe and Elite in our Helix mattress lineup comparison.
The Dusk is the back-and-stomach counterpart to the Midnight in Helix’s entry-level Core line: the same 11.5-inch hybrid platform, tuned to a medium feel with more push-back through the middle of the bed. It is the cheapest way into a Helix built for people who sleep on their back or front.
Published construction specifications
Layer details below were recorded from a September 2026 build sheet, not measured by Yawnder. Helix’s current product page also offers an optional GlacioTex cooling pillow top and optional ErgoAlign hip-support foam. The live configuration and named materials may differ from the recorded build; verify the exact order with Helix.

How the layers are supposed to work
The stack is short on purpose. A thin gel memory foam quilt gives the surface a little give without letting you settle in, then a 20-IFD Dynamic Foam comfort layer carries most of the contour. Underneath, two responsive foams step the firmness up quickly (24 IFD, then 36 IFD) so hips are handed off to the coil unit rather than sinking through the foam. That fast ramp is why the Dusk reads as medium under a back sleeper and closer to medium-firm under a stomach sleeper — the deeper you press, the harder it pushes back.
Where the Dusk sits against the rest of the line
The Dusk and Midnight share the same coil unit and the same height. The difference is the comfort layer: the Midnight leans on gel memory foam for side-sleeper contour, the Dusk uses a firmer Dynamic Foam that keeps the pelvis lifted. Step up and you get the Dusk Luxe, which adds a pillowtop, a zoned coil unit (13.5-gauge centre, 15.5-gauge edge) and a full reinforced perimeter, and the Dusk Elite, which adds microcoils and a taller build. Our three-tier Dusk comparison lays the differences out side by side.
What the build does well
- Firmness comes from a proper IFD ramp rather than a thick slab of soft foam, which is the right structure for back and stomach sleepers
- 8-inch pocketed coil unit with reinforced long sides
- Least expensive Helix aimed specifically at back and front sleeping
- Same 11.5-inch height as the Midnight, so bedding and bases carry over
Where it is limited
- The standard build has no stated zoned coil unit; the optional ErgoAlign foam adds targeted hip support at an extra cost
- Side sleepers who need more cushioning should compare the actual mattress and its optional pillow top
- The recorded foam densities alone do not establish how long a particular mattress will last
- Yawnder has not measured it yet, so there is no independent cooling, motion or edge figure to hold against the spec sheet
Who should buy it, and who should not
Consider Dusk if you sleep on your back or stomach and want a medium-feel hybrid. Side sleepers should compare shoulder pressure against the Midnight, and larger sleepers may also want to compare the Helix Plus Luxe. Body weight, shape and preferred feel all matter; we have not established a tested weight cutoff for Dusk. The optional ErgoAlign layer provides another way to add targeted hip support.
Current options, delivery and returns

The optional GlacioTex cooling pillow top was listed at $299 more and ErgoAlign support at $199 more; prices and promotions can change. Compare the completed configuration, not just the starting price. The mattress is shipped compressed; in-home setup and old-mattress removal can be selected where available for an additional charge.

Common questions
Is the Dusk firmer than the Midnight? Helix rates both medium, but the Dusk’s comfort layer is firmer, so it feels more supportive under the hips and less contoured at the shoulder.
Does it work on an adjustable base? Helix states that every current model, including the Core hybrids, is adjustable-base compatible.
Does Yawnder have a score for it? Not yet. When it goes through an instrument session in Encinitas, the score and the measured rows will appear on this page automatically.
What does it cost right now? Helix runs promotions almost continuously, so we do not print a fixed price. Check today’s Helix price and active promotion below.
