NM Mattresses Double & Full Mattress Accessories Split Queen Box Springs 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.
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
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
