Firm Top Rated Adjustable Base Compatible 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.
Top-rated mattresses are the models customers score highest for comfort, support, and value — shop with confidence from the beds real sleepers love most. Compare every top-rated 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.

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.
