With the Beautyrest Cool Wave PLUS 3" Mattress Topper, sleep support has never felt this good. With an extra inch of comfort compared to the 2” Cool Wave Mattress Topper, this convoluted wave pattern adjusts and responds to the body’s individual contours – especially around the shoulders and hips – for a luxurious feel and increased pressure relief. The peaks and valleys of the topper’s waves enhance airflow and heat dissipation for the ultimate in cooling and comfort. Beautyrest mattress toppers are manufactured with 100% CertiPUR-US-certified memory foam so you can trust that what you’re sleeping on was made with quality and safety in mind.
