Helix Sleep Twilight Mattress

The Twilight is specifically engineered for a firm feel, which is generally preferred by back and stomach sleepers. If you are a side sleeper who requires significant pressure relief for your shoulders and hips, you might find this model too firm.

The hybrid design uses individually wrapped steel coils paired with memory foam, which helps isolate motion significantly better than traditional innerspring mattresses. This makes it a solid choice for couples who don't want to be disturbed by a partner's movement.

TENCEL™ is a naturally breathable, moisture-wicking fabric that helps regulate temperature by promoting airflow. While it isn't an active cooling system, it is highly effective at preventing heat buildup compared to standard polyester covers.

The Twilight features reinforced full perimeter edge support. This design prevents that 'rolling off' sensation when you sit on the side or sleep near the edge, effectively increasing the usable surface area of the mattress.

Yes. The mattress is both CertiPUR-US and GREENGUARD Gold certified. These certifications ensure the foam is made without harmful chemicals like ozone depleters, mercury, or lead, and that the product meets strict standards for low chemical emissions.

The limited lifetime warranty covers manufacturing defects, such as sagging greater than one inch or issues with the mattress cover. It does not cover normal wear and tear or personal comfort preferences, so be sure to utilize the 100-night trial to ensure the firmness is right for you.
