• 【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 king 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 king 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 king size mattress.
• 【7-Zone Support for a Balanced, Medium-Firm Feel】 Our Shadow S-Support Core is engineered with seven precision-calibrated zones to provide targeted support for back pain relief. It maintains alignment for the lumbar region while ensuring balanced comfort, achieving a supportive Medium Firm Mattress feel. This makes it an ideal firm king mattress for those seeking firmer, aligned support.
• 【Find Your Fit Risk-Free: 110 Nights, On Us】 Sleeping preferences vary. That’s why we offer a 110-Night Trial on this king Mattress in a Box. Your mattress in a box ships directly—unbox, allow 72 hours to expand, and try it. If it’s not your perfect fit, we arrange a hassle-free return. We’re confident it could be your Best Mattress choice.
