King Memory Foam Memory Foam Copper, Charcoal or Graphite Infusion Mattress Features That Are Most Important For You

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.
Memory foam mattresses are all-foam beds, with no springs, and at least one memory foam comfort layer. They contour to your body, relieving pressure at the hips and shoulders while absorbing movement, so you are unlikely to feel a partner turn over. The cradling, hugged feel suits side sleepers and couples. Coil beds with memory foam are listed under Hybrid.
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.

Find your perfect mattress by feature—coast to coast. Compare cooling, low motion transfer, temperature regulating, pressure point relief, hypoallergenic, organic, eco‑friendly, and mattress‑in‑a‑box options. Filter by size (Twin, Twin XL, Double, Queen, King, California King) and firmness to match your sleep style anywhere in Canada.
