King Split Head Medium Cooling Fabric Copper, Charcoal or Graphite Infusion Memory Foam All
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
A cooling fabric cover is knit with special yarns or treated with phase-change material that absorbs heat, so the surface feels cool when you lie down and helps move warmth away. It is the first layer your body touches, so it works well with cooling foams underneath. For beds built around cooling overall, see Cooling Technology under Product Features.
These mattresses blend copper, charcoal, graphite or similar minerals into their foam layers or cover fabric. These materials conduct heat well, helping move warmth away from your body, and are also used to help keep the mattress fresh by resisting odour. A good place to start if you sleep warm and want cooling built into the materials themselves.
Every mattress here has at least one layer of memory foam, in the comfort layers or quilted into the cover. Memory foam softens with body heat and slowly moulds to your shape, easing pressure at the shoulders and hips and absorbing movement. You will find it in all-foam beds and in hybrids, where it sits above pocket coils. For all-foam memory foam beds only, use Mattress Type.
