How do SHEEX® cooling sheets actually keep you cool?
SHEEX® cooling sheets are made with our performance knit fabric, which is engineered to wick moisture away from your skin and disperse it across a larger surface area. This helps heat and sweat evaporate more quickly than traditional cotton sheets, creating a cooler, drier, and more comfortable sleep environment throughout the night.
What is the SHEEX® 60-Night Sleep Guarantee?
Try your SHEEX® sheets for 60 nights, risk-free. If they aren't the most comfortable sheets you've ever owned, simply return them within the trial period for a refund. No questions asked.
Do SHEEX® sheets stay soft after washing?
Yes. Unlike traditional cotton sheets that can wear down over time, SHEEX® performance fabrics are designed to maintain their softness, stretch, and shape wash after wash. For best results, machine wash cold and tumble dry on low heat.
Will SHEEX® fitted sheets fit a deep mattress?
Yes. SHEEX® fitted sheets are designed with deep pockets and stretch to fit mattresses up to 18 inches deep, including pillow-top, memory foam, hybrid mattresses and adjustable bases.
What's the difference between the SHEEX® sheet collections?
Each SHEEX® sheet collection is designed with a unique fabric and feel to meet different sleep preferences. Whether you're looking for maximum cooling, an ultra-soft feel, or elevated luxury, there's a SHEEX® collection for you.
