NM Mattresses Split Queen Box Springs Double & Full Mattress Accessories attresses with a Removable Cover All

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.
A split queen box spring is a standard queen foundation built in two halves (each about 30″ × 80″) instead of one solid piece — so it slides up narrow staircases, around tight corners, and into condos and lofts where a one-piece queen box spring simply won't fit. Together the two halves support a standard queen mattress (60″ × 80″) exactly like a regular box spring. Shop split queen box springs and foundations matched to Sealy, Serta, Beautyrest, Simmons, Stearns & Foster and more — free delivery across Canada. • What it is: a queen box spring that splits into two ~30″ × 80″ halves • Why: fits up tight stairwells and into condos/lofts a one-piece can't • Supports a standard queen mattress (60″ × 80″) — same support as a solid box spring • Split box springs and foundations (plus compatible bed frames) • Brands: Sealy, Serta, Beautyrest, Simmons, Stearns & Foster, Springwall, Galaxy & NM • From $162 — free Canada-wide delivery
Everything for a double (full) bed in one place, sized to the 54″ × 75″ fit. "Double" (the Canadian term) and "full" (the US term) are the same size, so any full-size accessory fits. Shop double/full mattress protectors, sheet sets, box springs, bed frames and duvets from trusted brands, with free delivery across Canada. • Fits the double/full mattress: 54″ × 75″ (double = full) • Mattress protectors — waterproof, breathable and encasement styles • Sheet sets and duvets in double/full sizes • Box springs and foundations • Bed frames and bases • Brands: HealthGuard, Restguard, Hush, NM, Leggett & Platt, Sealy, Serta, Beautyrest & more • Accessories from $7 — free Canada-wide delivery
Hundreds of our mattresses come with a removable, washable cover — unzip and take it off to machine-wash or spot-clean, which is great for allergies, kids, spills and keeping your bed fresh between deep cleans. These are mostly our foam, memory foam, gel-foam, latex and hybrid models — the bed-in-a-box-style builds — and they span value to luxury: NM, Springwall and Chirofoam, the Sealy Cocoon series, Serta iComfort and iComfort ECO latex, and Tempur-Pedic. You'll find every firmness from plush to extra firm, from about $109 to premium. Every mattress includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What it means: a removable cover you can unzip to machine-wash or spot-clean • Great for: allergies, kids, spills, and keeping your mattress fresh • A large selection — mostly foam, memory foam, latex and hybrid (boxed-style) builds • Spans value to luxury: NM, Springwall, Chirofoam, Sealy Cocoon, Serta iComfort & iComfort ECO, Tempur-Pedic • Firmness from plush to extra firm, from about $109 to premium • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
