Sealy mattresses are engineered for dependable, body-aligning support — many featuring Posturepedic Technology that reinforces the centre third where you need it most. Compare every option below by feel, size, 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.
Sealy® Essentials mattresses provide reliable comfort and support at a budget-friendly price. This collection offers the perfect balance of innerspring support and cooling foam comfort, delivering Sealy quality to Canadians at great value.
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.
