King Split Head Queen Queen Split Head Plush Mattresses Medium Mattresses Premium Mattresses Springwall Adjustable Bed Base Friendly
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
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

What Makes a Mattress Adjustable Base Friendly?
An adjustable base friendly mattress is designed to flex and bend repeatedly without damaging its internal structure. Not every mattress can handle this — traditional innerspring models with rigid continuous-coil systems and thick euro-tops can crease or lose support when elevated. The best options for adjustable bases include memory foam, latex, hybrid pocket-coil, and individually wrapped pocket coil mattresses, all of which articulate smoothly at the head and foot sections.
At National Mattress, every product listed in this category has been verified as adjustable base compatible by the manufacturer. Key features to consider include mattress height (models under 14″ generally flex most easily), coil type (pocket coils move independently and bend better than connected coils), and foam density (higher-density foams maintain their shape through thousands of flex cycles). If you already own a Lifestyle adjustable base or are planning to pair your mattress with one, look for models with low motion transfer and pressure point relief to get the full benefit of zero-gravity and elevated sleeping positions.
