Plush Memory Foam Side Sleeper Edge Support All Mattresses

Plush mattresses offer a soft, cushioning surface that lets your shoulders and hips sink in for pressure relief. They suit side sleepers, lighter bodies, and anyone who prefers a sink-in, hug-like feel over firm support. Compare every plush option below by brand, profile, and price.
Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
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.
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.
