Helix Midnight Mattress
A medium-feel hybrid mattress engineered to cradle your shoulders and hips with up to 1,000 individually wrapped coils beneath. The Goldilocks mattress — not too soft, not too firm.
Consistently ranked the best mattress for side sleepers by Wired, Forbes, and GQ. CertiPUR-US® certified. Made in the USA.
Engineered for the Way You Actually Sleep
Every layer and material in the Helix Midnight Mattress is purpose-built for side sleepers and couples who refuse to compromise on their rest. Here is what sets it apart from every other hybrid mattress on the market.
High
Exceptional Pressure Relief
Memory Plus Foam cradles your shoulders and hips — the exact pressure points that dig in when you sleep on your side. Wake up without the aches that come from an unsupportive mattress.
Excellent
Zero Motion Transfer
Individually wrapped coils move independently from one another. When your partner shifts at 3 a.m., you will not feel a thing — making the Midnight the best mattress for couples.
Strong
Full-Surface Edge Support
Reinforced perimeter coils extend all the way to the edges, giving you every usable inch of the mattress. Sit on the side of the bed or sleep near the edge without any roll-off sensation.
Good
All-Night Cooling
The hybrid coil construction allows natural airflow through the support core, dissipating body heat far more efficiently than traditional all-foam mattresses. Sleep cool from lights-out to sunrise.

Award-Winning Design
The Helix Midnight Mattress has been consistently ranked as the best overall mattress for side sleepers by the world's most trusted technology and lifestyle publications for multiple consecutive years.
The Goldilocks Zone
Medium Firmness (5.5–6.5)
Rated a 5.5 to 6.5 on a 10-point firmness scale, the Midnight lands squarely in the most universally comfortable range — firm enough to keep your spine aligned, soft enough to eliminate pressure points.
Built for Side Sleepers
Contours to every curve, relieves every pressure point
Zero Motion Transfer
Sleep undisturbed, no matter how restless your partner
Five Layers. One Perfect Night.
The Helix Midnight Mattress is a hybrid mattress, combining the pressure-relieving benefits of premium foam with the breathable support of a coil system. Every component is selected with a single purpose: to give side sleepers the ideal combination of deep comfort and lasting support.
Up to 1,000 wrapped coils
Independent response system
Hybrid Construction
Premium Foam + Coil System
Breathable Surface
Breathe Knit Cover
The soft, moisture-wicking knit cover allows air to circulate from the very first point of contact. It's gentle against skin and designed to regulate your body temperature throughout the night. Upgrade to the GlacioTex™ Cooling Cover for an even more pronounced cool-to-the-touch sensation.
Comfort Layer
Memory Plus Foam
Helix's proprietary Memory Plus Foam blend contours precisely to your body's exact pressure points — especially the shoulders and hips that side sleepers rest on. It delivers cradling pressure relief without the deep "stuck" feeling of traditional memory foam, so you can move freely all night.
Transition Layer
High-Grade Polyfoam
A high-density transition polyfoam layer bridges the gap between the soft comfort foam and the firm coil support below. It provides ergonomic zoned support, prevents uncomfortable "bottoming out," and ensures every movement is smoothly cushioned and controlled.
Support Core
Up to 1,000 Wrapped Coils
The heart of the Helix Midnight Mattress: up to 1,000 individually wrapped pocketed coils that respond independently to every curve and contour of your body. They deliver targeted support where you need it most, ensure zero motion transfer between sleep partners, and allow air to flow freely through the mattress to keep you cool.
Foundation
DuraDense Base Foam
A structural, high-density foam base anchors the entire coil and foam system. It provides a stable, non-compressible platform that maintains the structural integrity of the mattress for its full lifespan — backed by a 10-year warranty against any defects in materials or workmanship.
Midnight or Midnight Luxe?
Both models are built on the same award-winning Helix Midnight foundation. The standard Midnight is ideal for side and combination sleepers who want exceptional comfort and support. The Midnight Luxe adds zoned lumbar technology, a premium pillow top, and a TENCEL™ cover for couples who demand the very best sleep experience available.
