Springwall Foam mattresses provide all-foam comfort with excellent pressure relief and motion isolation. These Canadian-made mattresses use high-density foams (including eco-friendly BioFoam) to offer supportive, budget-friendly sleep solutions.
Springwall H2 Chiropractic mattresses represent the pinnacle of luxury and support in the Springwall lineup, handcrafted in Canada with premium hybrid technology for an ultra-comfortable, chiropractor-approved sleep experience. Springwall Chiropractic® and the Canadian Memorial Chiropractic College (CMCC) have joined forces to improve the sleep of Canadians with a long-term funding agreement to aid the Research & Development with the purpose of maintaining and improving health through better sleep.
Not every mattress can bend with an adjustable base — but these can. Every mattress here is built to flex with the head and foot articulation of an adjustable base without damaging the comfort layers, so you can read, relax in Zero-Gravity or elevate your legs with confidence. In fact, over 90% of our mattresses are adjustable-compatible, spanning memory foam, hybrid and pocket-coil constructions from every brand — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and more — at every budget from about $109 to premium. Foam and hybrid models flex most easily, while rigid, thick tight-top innersprings generally don't. Pair any of these with one of our adjustable bases, and every mattress comes with a 365-night sleep trial and free delivery across Canada. • What this means: mattresses built to flex with an adjustable base's head & foot articulation • Over 90% of our mattresses are adjustable-compatible — every brand, every budget ($109+) • Best constructions for adjustable bases: memory foam, hybrid and pocket-coil • What usually won't work: rigid, thick tight-top innersprings that don't bend • Pairs with our adjustable bases (including split-king for independent sides) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
