Medium Premium Edge Support Yes All Mattresses

Medium mattresses balance cushioning and support — soft enough to relieve pressure, firm enough to keep your spine aligned. This medium-firm feel is the most universally comfortable choice, suiting combination sleepers, couples with different preferences, and most back and side sleepers. Compare every medium option below by brand and profile.
Premium mattresses step up the materials, support systems, and comfort layers for a noticeably more refined sleep — without the top-tier price. They suit shoppers who want lasting quality and a more luxurious feel for their primary bedroom. Compare every premium option below by brand, type, and feel.
Edge-support mattresses use reinforced perimeters so you can sleep right to the edge without roll-off and get firm support when sitting on the side — ideal for couples maximizing space. Compare every edge-support 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.
