The Serta® iComfort® Blue 100 Gel Memory Foam mattress offers cooling, pressure-relieving comfort while also supporting every curve of your body. Plus, the layer of EverCool® Fuze™ Gel Memory Foam helps enhance breathability to promote airflow and further reduce heat buildup. Serta’s Balanced Support™ Foam provides the perfect balance of firming comfort and the six-inch Ultimate Edge® Foam Core ensures optimal support and helps reduce edge roll-off. All Serta iComfort mattresses are designed and assembled in the USA, leveraging Serta’s 85 years of manufacturing expertise. In addition, all of Serta’s foams are Certi-Pur® certified, meeting their standards for content, emissions and durability, and are analyzed by independent, accredited testing laboratories. Serta’s focus on quality is one of the reasons that Serta iComfort has been named a Consumer’s Digest Best Buy for 6 years in a row and has earned the Women’s Choice Award for mattresses for 4 years in a row.*


Additional Special Features:

  • 3-in-1 Leg Design: Innovative design allows the foundation legs (tapered wooden legs included) to be adjusted to change the bed height (3” to 8”). The color of base is gray uptown shadow ticking. Headboard brackets are included.
  • Exclusive MegaFit™ Retainer: The Velcro mattress retainer system keeps the mattress from sliding when adjusted, removing the need for unsightly metal bars.
  • Wall Saver: Ensures your mattress set stays in position as you adjust the position of your foundation. This way you'll always be close to your nightstand and you can use a headboard with your foundation.
  • Zero Clearance Design: Allows the foundation to easily fit into platform frames (with or without legs) and sleigh beds.
  • USB/110V Power Ports: USB/110V charging connections are located on each side of the base and on the underside of the head section of the platform. Charge two smart devices at the same time.
  • Convenience Lighting: Lights installed under the bed create a relaxing atmosphere while you're reading in bed and help you find your way if you need to get up in the middle of the night.
  • Zero G® Pre-set Position: One-touch button that raises the legs slightly above the heart to promote circulation and relieve pressure off the lower back.
  • App with integrated Bluetooth: Sleep connectivity by FullPower
  • Digital Remote: Shows real time bed articulated angles. Control your base using your smart phone or tablet through Serta SleepGPS™, a Sleeptracker® app available for download from the Apple iTunes Store or Google Play Store.
  • Magnetic Remote Holder: A magnetic remote control attaches to magnet embedded on the side of the base keeping the remote control in reach of the user at all times.
  • Wireless Motion-Sensitive Backlit Remote: Includes buttons that illuminate when the remote is picked up and features four pre-set positions (Flat, Lounge, TV/PC, Zero G®) for added convenience.
  • Smart Sync™ Pairing System: Synchronization has never been easier. Simply connect two Twin XL or California King Split bases with the sync cord provided. Each remote will operate both bases simultaneously. This feature applies to Twin XL and California King Split sizes only. Note: Queen size includes one base; standard King size includes (2) divided bases banded together and does not allow for separation or individual articulation.

**While many have experienced these benefits from an adjustable foundation, these claims have not been validated by medical testing. Your bed's foundation is not a medical device. Please consult your doctor if you suffer from medical conditions.
