Experience cooler, quieter, more supportive sleep with the Evann 10"/12" Medium Firm Hybrid Mattress. Cooling gel memory foam with CrystalCool™ Temperature Balance gently contours to the body for targeted pressure relief around the shoulders, back, and hips, while breathable construction promotes airflow and helps disperse excess body heat throughout the night. Beneath the comfort layers, individually wrapped pocket coils respond independently to movement, delivering advanced motion isolation to help reduce partner disturbance while providing stable, responsive support. The balanced medium-firm feel combines cushioning and support for side, back, and combination sleepers. Reinforced center and edge support improve stability across the entire sleep surface, providing dependable support from the middle of the mattress to the perimeter and maximizing usable sleeping space. Designed for a cleaner, more comfortable sleep environment, Evann combines antimicrobial, hypoallergenic, anti-static and dust-mite-resistant materials with carefully selected certified components. CertiPUR-US®, OEKO-TEX® and SGS certifications provide additional confidence in material quality and safety. Available in 10" and 12" profiles across Twin, Twin XL, Full, Queen, and King sizes, Evann arrives conveniently compressed as a mattress in a box for easier delivery and setup. Simply unbox, unroll, and allow 48–72 hours for full expansion. Backed by a 10-year limited warranty.
