Boxspring Split Queen Box Springs SealySupport™ Foundations & Boxsprings Canada Mattress Accessories

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
