Firm Memory Foam Great Value Back Sleeper Clearance Edge Support All Mattresses

Firm mattresses give you a solid, supportive surface with minimal sink — keeping your spine aligned and making it easier to move and get in and out of bed. They're the top choice for back and stomach sleepers, heavier bodies, and anyone who finds softer beds uncomfortable. Compare every firm option below by brand, profile, and price.
Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
Great Value mattresses deliver dependable comfort and support at our most affordable prices — a smart pick for guest rooms, kids' rooms, students, and budget-minded shoppers. Compare every great-value option below by brand, type, and feel.
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.
Clearance mattresses are marked down to clear — floor models, discontinued lines, and overstock at our deepest discounts while quantities last. Compare every clearance option below by brand, type, and price.
Edge-support mattresses use reinforced perimeters so you can sleep right to the edge without roll-off and get firm support when sitting on the side — ideal for couples maximizing space. Compare every edge-support option below by brand, type, and feel.
