A medium-firm pocketed-coil hybrid from Helix Sleep — pressure relief without the heat.
The Helix Midnight Medium Hybrid Elite Mattress is a medium-firm pocketed-coil hybrid mattress built for back sleepers and most body types. Helix builds each mattress to the sleep profile it's named for, with individually wrapped coils for motion isolation and a CertiPUR-US foam comfort system. At 15", it sits in the premium profile range — generous enough for adjustable bases yet still easy to sheet.

Individually wrapped coils flex independently for support that responds to your body, not the other way around.
A reinforced center third keeps the spine aligned across every position.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.

About this mattress
Helix Midnight 15" Medium Hybrid Elite Mattress
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.
Technology & Construction
The Helix Midnight 15" Medium Hybrid Elite Mattress is a hybrid mattress built around individually wrapped coils and responsive comfort foam. Each coil in the system is independently wrapped, meaning it compresses and responds to pressure independently of the coils around it. This provides three key benefits: targeted support that adapts to different body weights across the sleep surface, excellent motion isolation so partner movements don’t transfer across the bed, and continuous airflow through the open coil structure for cooler sleep. The comfort foam layer on top of the coils is configured specifically for the Midnight’s medium profile. The Elite tier adds a premium cooling pillow-top cover with enhanced temperature regulation, a taller 15-inch profile with additional comfort foam, and upgraded materials throughout. It represents the premium tier of the Midnight line. Reinforced foam encasement around the perimeter provides edge-to-edge stability and maximizes the usable sleep surface for both solo sleepers and couples.
Who This Mattress Is Best For
Helix’s Sleep Quiz recommends the Midnight for combination sleepers and couples who need a versatile comfort level. The medium profile works for back, side, and stomach sleeping, adapting to position changes throughout the night. The comfort foam provides enough cushioning for side sleeping without being so soft that back and stomach sleepers lose alignment. This is Helix’s most popular firmness range and the most common recommendation from the Sleep Quiz.
