【Targeted Comfort & Advanced Motion Isolation】 Experience relief at key pressure points with the GelFusion Gel Memory Foam layer, which contours to your body in this Hybrid Mattress. Beneath it, our MotionLock Individually Wrapped Pocket Springs are tuned to minimize motion transfer across the Bed Mattress and provide responsive, zoned support for undisturbed sleep, defining the quality of a premium twin XL mattress. 【ShadowBreeze Comfort Surface: Engineered for Coolness & Safety】 The ShadowBreeze performance-knit fabric incorporates advanced thermo-regulating fibers to enhance airflow, making it a Cooling Mattress surface. It provides a Soft, durable, and skin-friendly feel. Certified to CertiPUR-US standards, it ensures a healthy foundation for a twin XL memory foam mattress, free from concerns like those associated with some Memory Foam Mattresses. 【Breathable Side Mesh Enhances Dual Cooling】 The breathable mesh sides promote continuous airflow to vent heat. This works in tandem with our two core cooling technologies: the ShadowBreeze fabric and the Gel Memory Foam layer. This open-cell, Cooling Foam circulates air and dissipates heat efficiently, preventing heat buildup for a consistently cool sleep on a twin XL size mattress.
