Blue Fusion 500 Extra Firm
Twin XL

Experience superior firm comfort combined with the Serta iComfort Hybrid Blue Fusion 500 Extra Firm mattress. It features Serta exclusive TempActiv™ gel memory foam and a layer of Serta® Support Foam for enhanced airflow and firm, yet cushioning, comfort.

Top Layers of Comfort
With 2” of TempActiv™ Gel Memory Foam and 2” of Serta® Support Foam, you’ll feel supported and caressed by the luxurious foam layers as they take away pressure points, relax your spine, and help you drift off to a more rejuvenating sleep.

Core Layers of Support
The Serta® Hybrid Coil Support System with Best Edge® Foam Encasement is a next generation coil. It acts like 3 coils in one. The bottom part of the coil is very firm to provide extra support. The middle part of the coil gives slightly more to relieve pressure and the top portion is designed to provide excellent conformation to your body and spine.

Our Recommendation
An extra firm mattress in the iComfort Hybrid collection means it’s firm but not so hard that you loose pressure relief. The combination of advanced Serta foams and an exceptional coil system makes the Serta iComfort Hybrid Blue Fusion 500 Exta Firm mattress a great choice for the back or stomach sleeper looking for a harder sleep surface.
