Great Value Side Sleeper Adjustable Base Compatible Blue All Mattresses

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.
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.
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.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush. Every mattress is manufactured in Canadian factories using CertiPUR-US® certified foams and ships free across Canada with a 365-night sleep trial, price match guarantee, and manufacturer warranty coverage up to 25 years.
