Full Size Extra Firm Foam Core/No Coils Temperature‑Regulating Mattresses | Year‑Round Comfort & Balance Black Springwall Mattresses

Double/Full mattresses measure 54" × 75" — fifteen inches wider than a twin, giving a single sleeper plenty of room to spread out. They suit teens, single adults, and smaller bedrooms or guest rooms, and work for couples who prefer a cozier fit. Compare every double/full option below by brand, feel, and price.
Extra firm mattresses deliver the most supportive, no-sink surface we carry — maximum spinal support with the least give. They suit stomach sleepers, heavier bodies, and anyone with back concerns who needs a hard, flat feel. Compare every extra firm option below to find the right fit.
Foam core mattresses are built entirely from foam with no innerspring coils, for quiet, motion-free sleep and a consistent, supportive surface. They're lightweight, pair perfectly with platform and adjustable bases, and suit couples sensitive to movement. Compare every all-foam, no-coil option below by brand and feel.
Temperature-regulating mattresses balance heat and airflow to hold a neutral, consistent sleep temperature through the night — not too hot, not too cold. They suit sleepers whose temperature swings. Compare every option below by brand, type, and feel.
