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
The bed you sleep on is a system, and the pieces around the mattress decide how well it performs. National Mattress carries pillows matched to how you sleep, mattress protectors that keep spills and body oils out of the comfort layers, bedding and sheets, mattress toppers, and the support that goes underneath: box springs, bed frames, adjustable bases, and bedroom essentials such as headboards and platform bedframes. Choosing well is mostly a matter of matching each piece to your sleep position, your mattress height, and the support your mattress needs to sit flat.

How to Choose Bedding and Sleep Accessories
A bed is a system, and the pieces around the mattress decide how much of its comfort you actually feel. Start with the pillow, because it sets the angle of your neck and is the easiest thing to get wrong. Side sleepers need a high loft to fill the gap between ear and shoulder, back sleepers a medium loft that supports the curve of the neck without pushing the chin forward, and stomach sleepers the thinnest pillow they can tolerate. Fill then decides feel: memory foam, whether one moulded piece or granulated and loose, softens under body heat and holds the shape it takes; latex pushes back sooner and reads firmer and less enclosing at the same firmness label; feather can be punched into any shape and needs re-fluffing to keep it; and fiberfill sits lightest and washes most easily.
Below the sheets the job changes from comfort to protection and support. A mattress protector is a barrier against spills, sweat and skin oils, all of which reach the foam long before a stain shows. When you buy sheets, check the fitted pocket depth against your mattress height plus any topper, because a shallow pocket pops off the corners. Underneath, a mattress only performs on even, continuous support: a sound box spring, a bed frame with closely spaced slats, or an adjustable base if you want to raise the head and legs. Bedroom essentials such as headboards and platform bedframes finish the room.
Pillow Loft by Position
Loft, not softness, is the real decision. Match pillow height to the gap your sleep position leaves, then pick a fill that holds that height.
What a Protector Blocks
Liquid, perspiration and skin oils reach the comfort layers long before a stain shows, and foam does not wash. A thin knit faced laminate blocks all three and is close to unnoticeable; a quilted or padded protector softens the surface slightly.
Sheet Pocket Depth
Measure the mattress from top seam to bottom seam, add any topper, then buy a fitted sheet with a deeper pocket than that total.
Support Underneath
Foam and pocket coil beds need even support across the whole surface. Closely spaced slats, a sound box spring or an adjustable base all provide it.
