Medium Innerspring Back Sleeper New Arrival 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.
Innerspring mattresses use a coil support system for a responsive, bouncy feel with strong airflow that sleeps cool. They deliver reliable edge support and a classic "on top of the bed" feel at an accessible price — a fit for back, stomach, and combination sleepers. Compare every innerspring option below.
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.
New-arrival mattresses are the latest models to join our lineup — the newest builds, materials, and collections, fresh in stock. Compare every new arrival below by brand, type, and feel.
