Full Size Side Sleeper Best In Class Adjustable Base Compatible Yes All 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.
Side sleepers need a mattress that cushions the shoulders and hips while keeping the spine aligned — usually a plush to medium feel with strong pressure relief and contouring. The options below help side sleepers avoid shoulder and hip pain. Compare them by brand, feel, and profile.
Best-in-class mattresses are our top performers — the highest-rated, best-reviewed models for comfort, support, and durability. Compare every best-in-class option below by brand, type, and feel.
These mattresses are built to flex with adjustable bed bases — bending smoothly at the head and foot without damage — so you can raise, recline, and find your ideal position. Compare every adjustable-base-compatible option below by brand, type, and feel.
