Serta iSeries Vantage Firm Twin XL Mattress Uses Memory Foam to Bring Comfort to a Firm Mattress The Twin XL iSeries Vantage Firm Mattress is designed to give you the strong support you’ve come to expect from a firm mattress while also allowing you to enjoy the relaxing benefits of gel memory foam. The core of the mattress contains Duet Coil technology, which uses individually wrapped coils to provide the best support to every inch of the mattress. On top of the coils lies a layer of Cool Action Dual Effects Gel Memory Foam, which relieves your body’s pressure points through targeted support and expertly contours to your shape. Additionally, the memory foam contains MicroCool+ to maintain a temperature that’s just right for sleeping. Just because your body needs the sturdiness of a firm mattress doesn’t mean you can’t enjoy the pleasure of gentle, conforming memory foam. The Serta iSeries Vantage Firm Twin XL Mattress gives you maximum support and amazing comfort all in one.
  • The Twin XL iSeries Vantage Firm Mattress uses Duet Coil technology to provide complete support to your entire body
