Medium Mattresses Adjustable Bed Compatible Mattresses Pressure Relief Mattresses Springwall Mattresses
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
Not every mattress can bend with an adjustable base — but these can. Every mattress here is built to flex with the head and foot articulation of an adjustable base without damaging the comfort layers, so you can read, relax in Zero-Gravity or elevate your legs with confidence. In fact, over 90% of our mattresses are adjustable-compatible, spanning memory foam, hybrid and pocket-coil constructions from every brand — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and more — at every budget from about $109 to premium. Foam and hybrid models flex most easily, while rigid, thick tight-top innersprings generally don't. Pair any of these with one of our adjustable bases, and every mattress comes with a 365-night sleep trial and free delivery across Canada. • What this means: mattresses built to flex with an adjustable base's head & foot articulation • Over 90% of our mattresses are adjustable-compatible — every brand, every budget ($109+) • Best constructions for adjustable bases: memory foam, hybrid and pocket-coil • What usually won't work: rigid, thick tight-top innersprings that don't bend • Pairs with our adjustable bases (including split-king for independent sides) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Pressure relief mattresses are designed to contour to the shape of your body, cushioning the places that take the most weight — your shoulders, hips and joints — so you wake up without the aches and numbness a too-firm surface can cause. They use conforming memory foam, plush pillow-top and euro-top comfort layers, and pressure-mapping hybrids to spread your weight evenly and ease pressure points. They're especially worth a look for side sleepers, anyone with joint pain or arthritis, and lighter-weight sleepers. You'll find pressure-relieving builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in memory foam, hybrid and plush comfort. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: contours to your body to ease pressure at the shoulders, hips and joints • How it works: conforming memory foam, plush pillow-top/euro-top comfort layers, pressure-mapping hybrids • Best for: side sleepers, joint pain or arthritis, and lighter-weight sleepers • The benefit: even weight distribution — fewer aches, less numbness and tossing • Builds: memory foam, hybrid and plush comfort • Related: side sleepers (position) · plush (feel) · memory foam (type) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
