Medium Beautyrest Back Sleeper Cooling Technology All Mattresses

Medium mattresses balance cushioning and support — soft enough to relieve pressure, firm enough to keep your spine aligned. This medium-firm feel is the most universally comfortable choice, suiting combination sleepers, couples with different preferences, and most back and side sleepers. Compare every medium option below by brand and profile.
Beautyrest mattresses are built on individually wrapped pocketed coils that contour to your body and minimize motion transfer, often paired with cooling cover technology. Compare every option below by feel, size, and price.
Back sleepers do best on a mattress that supports the lower back while gently following the spine's natural curve — typically a medium to medium-firm feel. The options below balance support and pressure relief for back sleepers. Compare them by brand, feel, and profile.
Cooling-technology mattresses use gel-infused foams, phase-change covers, or cooling fibres that actively pull heat away from your body — ideal for hot sleepers who wake up overheated. Compare every cooling option below by brand, type, and feel.
