Medium Copper, Charcoal or Graphite Infusion Micro-Coils Marshall® Compatible with Adjustable Bed Adjustable Bed Base Friendly All
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.
Micro-coils are small coils used in the comfort layers, above the main support. They add bounce and airflow close to the surface and respond to small movements, giving a lighter, more lifted feel than foam alone.
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.
