Bedding/Sheets Bed Frame Mattress Adjustable Bases Boxspring Extra Firm Mattresses for Standard Bed Frames NM® Mattresses and Accessories

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
These mattresses are built for a standard bed frame, box spring or platform bed rather than an adjustable base — solid, no-flex support for a classic setup. Shopping by feel or build instead? Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.

NM Mattresses is our in-house brand, offering high-quality, budget-friendly beds tailored for Canadian sleepers — durable components and honest value without compromising comfort or support.

Shop NM across the NM®, Essentials, Cozy, Hi-Loft™, HD+™ Core, Orthopedic and Hospitality lines, in single/twin through king. Built in Canada and the USA with 5- to 25-year manufacturer warranties depending on the line, every NM mattress comes with our 365-night sleep trial and price-match guarantee.
