Serta Exhale IV Tight Top Hybrid 12.5 inch Mattress

This Exhale IV tight top twin XL hybrid mattress features several new, advanced cooling and support features, some of which you’ll find only at Dufresne, like the CoolTemp™ fabric cover. This advanced fabric, quilted over three layers of cushioning, temperature-regulating foam, uses phase change technology to create a soothing, cool-to-the-touch sensation that helps you fall asleep faster. Beneath the deeply quilted surface, layers of resilient, supportive latex and gel-infused memory foam, including CoolTwist® and our exclusive CopperLite,™ work together to reduce heat build-up for a cooler, more comfortable sleep environment. Another Dufresne exclusive, the TruResponse coil system, utilizes thousands of coils which conform independently to provide responsive, body-cradling support. Serta’s latest innovation, the Total Edge® foam encasement system with an enhanced lumbar support core, surrounds and provides structure to a system of individually wrapped coils that react to every contour of your body, ensuring a deep, comfortable sleep.
