The Helix Twilight is our firm model recommended for side sleepers and people who toss and turn at night. The mattress features memory foam with a dense foam feel and supports spinal alignment by providing pressure relief at your hips and shoulders. Firmer top layers of the mattress to give you the firm feel you need - no sink or give. Comfortable, yet solid under your body. Assembled in our Arizona factory with coils and foams we produce. CertiPUR-US and GreenGuard Gold certified, zero fiberglass.

Pressure Point Relief: Because of your sleeping position and body type, the mattress uses layers designed to cushion the pressure points of your shoulders and hips. Less pain, more comfort.

Side Sleeper Support: Best for side sleepers or those who toss and turn at night. The middle layers of the mattress are designed to support your body contours. (See our Helix Dawn mattress for a similar experience for back and stomach sleepers.)

Premium Cooling Covers: Choose between our Breathe Knit cover or upgrade to the GlacioTex™ Cooling Pillow Top for cooling tech that pulls heat away from your body.
