Plush Extra Firm NM® Mattress Selector

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
Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada. • Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface • Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support • Choose this over firm if a standard firm mattress still feels too soft • Consider firm or medium if you sleep on your side or want any cushioning • Constructions: tight-top and high-density foam (including orthopedic Chirofoam) • Brands: Beautyrest, Serta, Chirofoam, Springwall & NM • Prices: from $152 — an affordable, value-focused selection
NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. Compare every option below by feel, size, and price.
