Medium Mattresses Limited Stock Mattresses Mattresses Compatible with Adjustable Bed Base | Flex‑Friendly Foam, Latex & Hybrid Temperature‑Regulating Mattresses | Year‑Round Comfort & Balance 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
These mattresses are down to their last few units — when they're gone, they're gone. Limited stock spans every brand and price point, from value foam to premium hybrids by Sealy, Serta, Beautyrest, Tempur-Pedic and our own NM line, so there are options here at every budget. The upside of limited stock is speed: because these beds are physically in our warehouse right now, they're ready to ship and can arrive fast — often as soon as the next day in many areas. If you've found the one, order before someone else does. Every mattress includes our 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "limited stock" means: only a few units left — order before they sell out • In stock now: physically in our warehouse and ready to ship fast (often next-day in many areas) • Spans every brand and budget — value foam to premium hybrid • Brands: NM, Springwall, Chirofoam, Sealy, Serta, Beautyrest, Tempur-Pedic & more • Best for: shoppers who want their mattress quickly, or don't want to miss a model that's running out • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
These mattresses are built to flex with adjustable bed bases — bending smoothly at the head and foot without damage — so you can raise, recline, and find your ideal position. Compare every adjustable-base-compatible option below by brand, type, and feel.
Temperature-regulating mattresses balance heat and airflow to hold a neutral, consistent sleep temperature through the night — not too hot, not too cold. They suit sleepers whose temperature swings. Compare every option below by brand, type, and feel.
