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.
