Renew your tired old mattress or instantly upgrade a new mattress with the SleepJoy memory foam mattress topper. It will add comfort and support wherever it’s needed, including on that beat-up college mattress. Our premium memory foam adds a layer of luxury – gently cradling your body’s contours and relieving the pressure points that can cause sleep disturbances. Unlike some memory foam that traps heat, our ViscO2 memory foam is designed to be fully breathable. The open cell structure and air vents allow for incredible airflow, allowing heat to escape for a cooler, more comfortable sleep. Plus, ViscO2 is odor-neutral and doesn’t have that “new-foam smell” that can linger in other memory foam products. Our company is based in the USA, where all our foam is made. We have a passion for excellence, and closely adhere to all U.S. quality and environmental standards. This topper is the easy, cost-effective way to achieve that deep, rejuvenating sleep you long for. Simply unpack, unroll, and unwind.
