King Medium Compatible with Adjustable Bed Edge Support Mattresses Tempur-Pedic® Mattresses and Accessories
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
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

Express ShippingHow to Choose the Right Tempur-Pedic Mattress
TEMPUR® Material is the reason a Tempur-Pedic® mattress feels unlike other foam beds, and it is worth knowing what separates it from ordinary memory foam. It is viscoelastic and noticeably denser, and it responds to your body heat as well as your weight. Two things follow. It conforms very precisely, flowing away from the points of highest pressure instead of compressing evenly, spreading your weight across a wider area. And it recovers slowly without pushing back. A resilient foam or a spring returns energy to you, and that is what you feel as counter-pressure under a shoulder or hip. TEMPUR Material mostly stops resisting instead, which is why people describe it as being moulded rather than supported.
The same property explains the trade-offs. Because the material absorbs energy rather than returning it, movement barely travels, so a restless partner is close to unnoticeable. For the same reason it takes more effort to change position, and material that wraps closely holds warmth more than an open structure, so cover and layer choices matter if you sleep hot. Models built with premium spring coils or heat-tempered steel coils under the TEMPUR layers answer both: springs move air through the mattress and add a lift that makes turning over easier, keeping the conforming feel on top. The firmness options are Firm, Medium and Plush.
Precise Conforming
A denser viscoelastic material flows away from pressure rather than squashing flat, so weight spreads over more of the surface and the sharpest pressure points are relieved rather than merely cushioned.
Movement Absorbed
Energy goes into the material instead of bouncing back, so a partner getting up barely registers on your side. All foam leads on motion isolation, with pocketed coil hybrids close behind; our motion transfer guide sets out the order.
All Foam or Hybrid
Premium spring coils and heat-tempered steel coils sit beneath the TEMPUR layers to add airflow, a springier lift and a steadier perimeter. Compare the approaches in our hybrid, foam and innerspring comparison.
