It ships compressed in the compact WonderBox for easy handling and expands to its 4 in profile within 72 hours, making setup simple. The single biggest reason to buy is the combination of a fully memory foam construction swirled with cooling gel and a surface engineered for airflow that helps dissipate heat while providing a noticeably softer, more enveloping sleep surface.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Gel Swirl:\u003c\/strong\u003e The memory foam is swirled with cooling gel to help pull excess heat away from the body for a cooler sleep feel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWave Dynamics Airflow Surface:\u003c\/strong\u003e The ups and downs in the topper surface promote airflow across the foam to reduce trapped heat and improve breathability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWonderBox Packaging:\u003c\/strong\u003e Ships compressed in a smaller, more convenient box for easier transport into the bedroom and a reduced carbon footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull 4 in Memory Foam:\u003c\/strong\u003e A full 4 in of conforming memory foam adds softness and pressure relief while still fitting under standard or deep pocket fitted sheets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertiPUR-US Certified Foam:\u003c\/strong\u003e The foam meets CertiPUR-US standards for durability and content, offering some assurance about materials and performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-Year Limited Warranty:\u003c\/strong\u003e A worry-free 5-year limited warranty is included and the initial foam scent should dissipate within 72 hours.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis topper suits side and combination sleepers who want more cushioning at the shoulders and hips and those who sleep warm but do not want to replace a mattress.
