NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. 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.
Best-selling mattresses are the models customers choose most often — proven, popular picks across every budget and sleep style. Compare every best-selling option below by brand, type, and feel.
Mattress-in-a-box options are compressed, rolled, and shipped straight to your door for quick, easy setup — just unbox and let it expand, with the same comfort and support. Compare every mattress-in-a-box option below by brand, type, and feel.
