Key Benefits & Features

CoolFeel™ Pro System
- Advanced cooling fabric paired with highly breathable latex foam absorbs excess heat and circulates cool air, keeping you comfortably cool throughout the night.
5 ZoneResponse™ Design

True Response™ Latex Foam Core
- A highly responsive foam core derived from 100% natural latex for long-lasting support.
- Offers a springy, supportive feel and superior durability compared to traditional memory foam.
Naturally Derived & Locally Assembled

- Assembled in Canada to meet rigorous quality standards and ensure exceptional performance.

Professional-Grade Comfort & Support

Professional-Grade Latex Foam: Serta’s True Response™ Latex Foam provides a responsive, contouring feel that alleviates pressure points without the “sinking” sensation often associated with other foam types.
Plush yet Supportive: The combination of plush comfort layers and a supportive latex foam core offers the perfect balance of softness and spinal alignment.
Breathability & Cooling: The open-cell structure of latex, combined with cooling technologies, allows for superior airflow and temperature regulation.

Why Choose the SERTA iComfort Pro Latex Plush Mattress?
