King Memory Foam Copper, Charcoal or Graphite Infusion Marshall® Springwall® All

King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Every mattress here has at least one layer of memory foam, in the comfort layers or quilted into the cover. Memory foam softens with body heat and slowly moulds to your shape, easing pressure at the shoulders and hips and absorbing movement. You will find it in all-foam beds and in hybrids, where it sits above pocket coils. For all-foam memory foam beds only, use Mattress Type.
These mattresses blend copper, charcoal, graphite or similar minerals into their foam layers or cover fabric. These materials conduct heat well, helping move warmth away from your body, and are also used to help keep the mattress fresh by resisting odour. A good place to start if you sleep warm and want cooling built into the materials themselves.
Marshall® is a Canadian name in handcrafted, pocketed-coil sleep. Each Marshall mattress is built in Canada on an 842 tempered pocketed-coil system with high-density encased edge support, spanning the Crafted and Assured series in medium, firm and plush feels, plus matching boxsprings to complete your set. Backed by a 10-year warranty and free next-day delivery in Toronto.
Springwall is a proudly Canadian-made brand known for chiropractic-minded support and durable, value-driven construction. Compare every option below by feel, size, and price.
