NM® Mattresses and Accessories® Twin XL Size Mattresses for Standard Bed Frames NM
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.
Complete your Twin XL bed with accessories sized to the 39″ × 80″ fit — 5 inches longer than a standard twin, so regular twin sheets won't reach. Shop Twin XL sheet sets, mattress protectors, box springs, bed frames and adjustable bases, ideal for university dorms, tall sleepers, guest rooms and split-king adjustable setups (a king foundation is two Twin XL halves). Free delivery across Canada. • Fits the Twin XL mattress: 39″ × 80″ (5″ longer than a twin) • Sheet sets cut for the extra Twin XL length — a must for dorm beds • Mattress protectors — waterproof, breathable and encasement styles • Box springs and foundations; two Twin XL box springs build a split-king base • Bed frames and adjustable bases • Brands: HealthGuard, Hush, NM, Leggett & Platt, Sealy, Serta, Beautyrest & more • Accessories from $6 — free Canada-wide delivery
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.
