      About Sleep Disruptors

      Overview

      Experience the exceptional comfort of added layers of support foam with the Sandburg, the official mattress of the National Sleep Foundation. With a firmer feel than other beds in the collection, the Sandburg features two layers of Serta Support Foam for ultimate pressure point relief and gentle cushioning. For enhanced airflow and heat dissipation throughout the mattress, enjoy the contouring effect of the Cool Twist Gel Memory Foam for a more ideal sleep environment. Plus, our 825 Edition Custom Support Coil System provides ultimate pressure point relief and minimizes motion transfer for the restorative sleep you’ve been dreaming of. With the Sandburg you’ll experience better pressure point relief than ever before on a bed that’s suited to your comfort level.

      Benefits

      Let's Look Under The Covers
      PRESSURE RELIEF

      With Serta’s Cool Twist® Gel Memory Foam, cooling gel is swirled perfectly into a lush foam designed for long-lasting durability, pressure relieving comfort and heat dissipation.
      BREATHABILITY
      HyperTouch™ Comfort System
      Serta’s HyperTouch™ Comfort system replaces ordinary foam with a combination of specialized foam, engineered fibers, and premium stretch fabric. This system comfortably cradles your body from head to toe for better pressure point relief.
      PRESSURE RELIEF
      Serta® Comfort Foam
      A combined 1" of Serta Medium and Firm comfort foams reinforces the mattress, providing a solid, yet comfortable feel for restful sleep.
      SUPPORT
