Why We Love This

Perfect Sleeper® Cobalt Calm Extra Firm is an extra-firm, supportive mattress with a 12” profile, essential cooling features, and targeted support. Featuring an 825-coil density system, this classic quilted-top mattress offers zoned comfort, pressure relief, and memory foams that contour your body.
  • Cool feel™ fabric - a luxurious, breathable cover with a cool-to-the-touch sensation from technology that is plant-derived. Our biobased phase change material consists of 53% biobased content and is certified through the usda biopreferred® program.
  • Antimicrobial mattress protection - keeps your mattress fresh and clean from odor causing bacteria. This product protects the mattress but does not protect users against bacteria, viruses, germs or other disease organisms.
     
  • Cool twist® gel memory foam - this breathable, gel-infused memory foam gently cradles your body while promoting enhanced airflow.
     
  • 850 edition custom 3 zoned support coil system. This system of individually wrapped coils provides contouring, cradling support from edge-to-edge, minimizing the impact of your partner’s movements
     
  • Proudly 100% U.S.A. assembled
  • An Extra Firm mattress gives the sensation of lying on top of the mattress with little give
