Everything for a king bed (76″ × 80″) in one place. Shop king mattress protectors, sheet sets, box springs, bed frames, pillows and duvets — note that a king box spring is built as two split halves (each 38″ × 80″) so it's easy to move and fits up tight stairwells. Protectors from HealthGuard and Hush, box springs matched to your mattress brand, plus premium bedding, all with free delivery across Canada. • Fits the king mattress: 76″ × 80″ • Mattress protectors — waterproof, breathable and encasement styles • Sheet sets, duvets and pillows in king sizes • Box springs and foundations (a king ships as two split halves) • Bed frames and bases • Brands: HealthGuard, Restguard, Hush, NM, Leggett & Platt, Sealy, Serta, Beautyrest, Tempur-Pedic & more • Accessories from $13 — 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

Most of our mattresses come in a clean, neutral white or off-white cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by what actually matters: your size (twin to king), your comfort level (plush, medium, firm), or your preferred type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.
