Helix’s CoolShift Enhancing Sheets are engineered to help your mattress’s cooling features work better, and are more breathable and moisture-wicking than cotton. 

Here's the CoolShift difference:

• Heat transfer: Nano-sized channels allow heat to transfer through to your mattress so your GlacioTex Cooling Cover and CoolForce Layer can pull heat down and away from you.

• Breathability: More airflow than cotton, so heat escapes instead of getting trapped.

• Moisture-wicking: You stay dry if you sweat at night.

• Softness: Smoother and softer than cotton from the first wash, and only get softer over time.

If you have a cooling mattress, the CoolShift Enhancing Sheets are the better choice. They're designed to enhance your mattress's cooling features, not block them.

The CoolShift Enhancing Sheets are designed to enhance the performance of cooling mattresses, especially Helix mattresses with a GlacioTex Cooling Cover and/or CoolForce Layer that pulls heat away from the body. That said, they're a light and breathable option that works with any mattress to keep you cooler than traditional cotton or polyester.

If you wake up sweaty, kick off your blankets at night, or sleep hot, cooling sheets can make a big difference. The CoolShift Enhancing Sheets are especially effective if you have a cooling mattress, because they offer more effective heat transfer and airflow so your mattress's cooling features can reach your body and pull heat away from you. If you're not sure, try them for 30 nights risk-free. If you don’t love them, we’ll take them back.

Thread count refers to the number of threads (vertical and horizontal) in a square inch of fabric. Thread counts have long been marketed as the higher the better. But practically speaking, excessively high thread counts in a sateen weave can result in a heavier, less breathable sheet. Our 320 thread count provides the perfect balance of a soft, premium feel and a light, breathable finish.

No. CoolShift Enhancing Sheets are smooth and soft, but not slippery. The sateen weave gives them a subtle grip that keeps your sheets in place while still feeling luxurious.

Yes! We recommend washing your sheets on a warm, gentle cycle with similar colors. Tumble dry on low and iron on low as desired. Do not dry clean or bleach.

Our CoolShift Enhancing Sheets are designed with a deep pocket that fits mattresses from 11 - 17 inches in height. Each fitted sheet also includes a durable elastic band to ensure a snug fit.
