It's about creating a cooling experience that adjusts to your body temperature throughout the night. Our R&D team used a range of materials and technologies to develop the COOLING COLLECTION Mattresses Series , which provides both comfort and cooling support. But what makes COOLING COLLECTION so effective? In this article, we'll take you behind the scenes of the research and development (R&D) that went into creating this revolutionary cooling experience. From the materials used to the science of temperature regulation, we'll explain how our COOLING COLLECTION mattress is designed to offer the ultimate sleep experience. Why You Need a Cooling Mattress? When it gets warmer inside or outside, many people find it hard to sleep well because they get too hot at night. Overheating can cause you to wake up often, feel uncomfortable, and disrupt your sleep, especially during deep and REM sleep. For some, a hot mattress makes it nearly impossible to get the rest they need. Thus, a cooling mattress matters. A good cooling mattress helps dissipate body heat and regulate temperature, ensuring a more comfortable sleep. Does a Cooling Mattress Really Work? Yes, the BedStory cooling mattress uses materials such as PCMs, gel-infused foam, breathable covers, and POE Air Fiber layers, which have been shown to help regulate your body temperature. Cooling Gel-Infused Memory Foam The main reason the mattress stays cool is its gel-infused memory foam. Regular memory foam can trap heat, making you feel warmer. In contrast, gel memory foam has cooling gel beads that absorb heat and move it away from your body, keeping the surface cooler and more comfortable. These gel beads are spread evenly throughout the foam for consistent cooling. Phase Change Materials (PCMs) PCMs are incorporated into COOLING COLLECTION's design to regulate temperature. PCMs work by absorbing excess heat when the body becomes too warm and releasing it when the body cools down. This keeps the mattress at a comfortable temperature, so you don't get too hot or too cold. Breathable Mattress Cover The COOLING COLLECTION mattress features a breathable, moisture-wicking cover that enhances airflow. This fabric allows for better ventilation, ensuring that heat can escape and cooler air circulates throughout the night. The cover's moisture-wicking properties also help reduce sweat and keep you feeling fresh. Open-Cell Foam Technology Open-cell foam allows for greater airflow within the mattress. The air pockets in the foam improve ventilation, so your body heat won't get trapped in the mattress. The result is a mattress that stays cooler longer, providing consistent comfort throughout the night. Benefits of a COOLING COLLECTION Mattress COOLING COLLECTION BENEFITS Designed for cooler, drier, and more consistent rest. “The innovative design of the COOLING COLLECTION mattress helps improve sleep quality for people who struggle with overheating at night.” Consistent Sleep Temperature: Gel-infused foam, PCMs, and breathable materials help the mattress adapt to your body temperature through the night. Reduced Night Sweats: Temperature-regulating layers help prevent heat buildup and keep the sleep surface drier. Deeper, Uninterrupted Sleep: Better temperature control may help reduce wake-ups and support more restorative rest. All-Season Comfort: Balanced cooling helps the mattress feel comfortable in both warm and cool weather. Sustainable Design and Materials: CertiPUR-US foams and thoughtful materials help support safer, cleaner sleep. Shop COOLING COLLECTION → Final Thoughts The COOLING COLLECTION mattress is built around a layered cooling system rather than a single surface feature. Gel-infused memory foam helps move heat away, PCMs balance temperature shifts, breathable covers support airflow and moisture control, and open-cell foam helps reduce heat buildup inside the mattress. Together, these materials create a cooler, fresher, and more consistent sleep experience for hot sleepers and anyone who wants better temperature regulation through the night. FAQs How does the Cooling Collection mattress work? BedStory cooling mattress uses a combination of gel-infused memory foam to absorb and wick away heat, phase change materials (PCMs) to regulate temperature, and a breathable cover with open-cell foam to enhance airflow and prevent heat buildup. Will the Cooling Collection mattress feel too cold in winter? No. Phase change materials (PCMs) and a balanced design adapt to your body's temperature, providing cooling when you're warm and releasing heat when you're cool, ensuring comfort in all seasons. Is the Cooling Collection mattress good for night sweats? Yes. Its temperature-regulating technologies are specifically designed to reduce overheating and wick moisture away, helping minimize night sweats and discomfort. Are the materials in the Cooling Collection environmentally friendly? Yes. BedStory Cooling Collection mattresses feature non-toxic, sustainable cover fabrics and are designed with eco-conscious materials that are CertiPUR-US certified, ensuring they are free from harmful chemicals.
