Medium Springwall® Chiropractic® Sealy® Essentials MLILY® ChiroPro Serta® Perfect Sleeper® Cooling 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
Springwall mattresses offer robust, targeted support for proper spinal alignment. Springwall Chiropractic® and the Canadian Memorial Chiropractic College (CMCC) have joined forces to improve the sleep of Canadians with a long-term funding agreement to aid the Research & Development with the purpose of maintaining and improving health through better sleep.
