Blue 300CT Plush
Twin XL

The Serta iComfort Blue 300CT Plush mattress combines the feel of a medium plush mattress with the benefits of Serta’s latest breakthroughs in memory foam technology. It combines Serta TempActiv™ Gel Memory Foam with a layer of EverCool® Fuze™ Memory Foam for enhanced cooling comfort that also supports every curve of your body. It also features a layer of Deep Reaction™ Memory Foam for a substantial, deep-down feel not often found in traditional memory foam.

Top Layers of Comfort
Beginning with a TempActiv Touch Cover, the cooling effect is noticeable right at your fingertips.  Beneath the cover find additional cooling technology with ¾” TempActiv™ Gel Memory Foam giving you additional temperature regulation throughout night. 1” EverCool® Fuze™ Memory Foam contours and supports while also increasing airflow. 1” Serta® Balanced Support Foam provides a firm support feel. 1 ½” Deep Reaction™ Memory Foam adds another layer of conforming support.

Core Layers of Support
At the core of the Blue 300 you’ll find 6” of Serta® Ultimate Edge® Foam. This is the foundation for the advanced Gel Foams. It provides a firm and long-lasting support system.

Our Recommendation
The Serta iComfort Blue 300CT Plush mattress is a comfortably plush option with exceptional pressure relief. Great for all types of sleepers, we specifically recommend this model for side sleepers or back sleepers needing relief from painful pressure points.
