Medium Plush Memory Foam Foam Core/No Coils Natural & Organic Mattresses Default Category
Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
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.
Foam core mattresses are built entirely from foam with no innerspring coils, for quiet, motion-free sleep and a consistent, supportive surface. They're lightweight, pair perfectly with platform and adjustable bases, and suit couples sensitive to movement. Compare every all-foam, no-coil option below by brand and feel.
For a cleaner, more eco-conscious sleep, our natural and organic mattresses are built with materials you can feel good about — natural Talalay latex, organic cotton and wool covers, plant-based and soy-derived foams, and recycled fibres, with low-VOC, CertiPUR-US® certified components. They're a great fit if you want fewer synthetic chemicals, more sustainable materials, or a naturally breathable, hypoallergenic feel. You'll find genuinely certified-organic options — like GOTS organic cotton and organic latex from Natura and Evergreen — alongside natural-material and eco-friendly builds from Serta iComfort ECO, Sealy, Beautyrest and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What "natural materials" means: Talalay latex, organic cotton & wool, plant-based/soy foams and recycled fibres • Certified-organic options: GOTS organic cotton and organic latex (Natura, Evergreen) • Eco-friendly builds: Serta iComfort ECO (REPREVE recycled) plus low-VOC, CertiPUR-US® foams • Best for: shoppers who want fewer synthetic chemicals, sustainable materials, or a naturally breathable feel • Looking specifically for latex?
