The Helix Dusk is the medium profile Helix aims at back and combination sleepers, and the 11.5-inch standard build delivers that feel at the entry price of the line. Individually wrapped coils react to pressure one spring at a time, so your hips stay level on your back and your shoulder gets room when you turn to your side. The medium comfort foam above adds cushion without letting the midsection drop, and a reinforced foam perimeter firms up the edge.

Helix Sleep was founded in New York City by a team of engineers and product designers who were frustrated with the mattress industry’s one-size-fits-all approach. They asked a simple question: if people are different sizes, sleep in different positions, and have different pressure-relief needs, why does everyone buy the same mattress? Their answer was a lineup of hybrid mattresses designed around specific sleep profiles, each model engineered for a particular combination of body type, sleeping position, and firmness preference. Helix’s Sleep Quiz has matched millions of sleepers to their ideal mattress using data-driven recommendations based on sleep science research. Every Helix mattress is designed in New York and manufactured in Phoenix, Arizona, using CertiPUR-US certified foams. All materials are tested for quality and safety, and every mattress comes with a limited lifetime warranty, one of the strongest warranties in the industry, plus a 120-night sleep trial.

Read the full termsThe Dusk is Helix’s medium profile aimed squarely at back and combination sleepers, and the 11.5-inch standard build delivers that feel at the line’s entry price — $799 to $1,489 depending on size. It is the bed to shortlist when you want real support without sleeping on a board.
Individually wrapped coils react to pressure one spring at a time, so your hips stay level on your back and your shoulder gets room when you turn to your side. The medium comfort foam above them adds cushion without letting your midsection drop, and a reinforced foam perimeter firms up the edge for sitting or sleeping near the rail. CertiPUR-US certified foams, designed in New York, made in Phoenix, Arizona.
Choose the Dusk if you fall asleep on your back, wake up in a different position, or share the bed with someone who does — the coil system keeps that shuffling from crossing the centerline. Stomach-leaning sleepers who want firmer resistance should look at the Dawn 11.5"; the same medium feel in taller, plusher builds lives in the Dusk Luxe and Dusk Elite.

It suits: Back sleepers who want real support without sleeping on a board; Combination sleepers who change position through the night; Couples, since the coil system keeps movement from crossing the centerline.
