mi away,


The Special iComfort EFX Edition offer’s a deeper, plusher comfort that goes beyond the standard iComfort.  Experience the benefits of our gel memory foam from an extra-firm mattress.  This iComfort® EFX model features a layer of Serta® Support Foam below an enhanced layer of our Cool Action™ Dual Effects® Gel Memory Foam, allowing you to enjoy the contouring comfort of memory foam with a firm sleep surface.  It also features our exclusive EverFeel™ Technology for a difference you’ll feel the moment you lie down.      

All foam is not created equal. iComfort features our breakthrough Cool Action™ Dual Effects® Gel Memory Foam.  This is the world’s first material to infuse both our MicroSupport® and MicroCool+™ gels into premium memory foam for an extremely comfortable and supportive sleep surface while helping to reduce the heat build-up that can be associated with memory foam mattresses.    


  • Avantec Performance Fabric – an IComfort EFX Advantage 

Comfort Layers

  • EverFeel™ Technology for a difference you’ll feel the moment you lie down
  • 2 Layers of Serta Support Foam
  • 33% more dual-action gel memory foam when compared to standard iComfort® mattresses

Support System

  • Comfort Last Foam Core with Ultimate Edge Support - Designed to help support your body throughout the night while reducing edge “roll-off” so you have more room to stretch.
