Medium MLILY® Queen Size Split Queen Box Springs All

Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
MLILY® is a global sleep brand known for memory-foam comfort and modern hybrid design, made in the USA. From the cooling PowerCool and the pocket-coil Midnight and ChiroPro hybrids to the all-foam WellFlex and the officially licensed Manchester United collection, MLILY pairs AeroFusion™ foams with individually pocketed coils for supportive, motion-isolating sleep. Backed by warranties up to 10 years and free next-day delivery in Toronto.
A queen bed measures 60″ wide by 80″ long — Canada's most popular size, so it gets our deepest selection in every accessory. Everything here is cut to fit a standard queen mattress exactly, with split options available where one piece won't clear a tight stairway or hallway. If you're unsure of your size, measure the mattress rather than the frame: queen accessories fit 60″ × 80″.
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
