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
Moisture-wicking mattresses are built to keep you dry — drawing sweat and moisture away from your body and letting it evaporate instead of pooling against the surface. Using moisture-wicking and breathable cover fabrics (like Tencel and performance knits) plus ventilated foams and coil airflow, they help you stay fresh and dry through the night. They're especially worth a look if you deal with night sweats, run warm and sweaty, or are managing temperature changes from menopause. You'll find moisture-wicking builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot and want active cooling? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: wicks sweat and moisture away so the surface stays dry • How it works: moisture-wicking & breathable covers (Tencel, performance knits), ventilated foams, coil airflow • Best for: night sweats, sweaty sleepers, and temperature changes from menopause • The benefit: a drier, fresher sleep surface — less clammy, less trapped heat • Related: cooling (sleeps cold) · temperature-regulating (balanced temp) · breathable (airflow) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
