Expert Review by Jed
The Cal King Serta iComfort Blue 300 Firm Mattress is one of the firmest models in the iComfort collection, and it is the first to utilize Deep Reaction Memory Foam. With a rating of 2.5 on our Comfort Scale, it has an almost hard level of comfort, which is ideal if you're on the lookout for one of the firmest mattresses available.

The Serta iComfort Blue 300 Firm Mattress features a smooth top quilt design that is breathable and thin, which allows the comfort layers to conform better to the curves of your body. Key comfort components include TempActive Max Gel Memory Foam, a premium memory foam with TempActive temperature regulation technology integrated right into the surface to achieve immediate as well as long term cooling. A layer of EverCool Fuze Gel Memory Foam ensures consistent pressure relief to help prevent tossing and turning and promote deep REM sleep. A layer of Serta Support Foam works in conjunction with the Deep Reaction Memory Foam to create a solid underlying feel. Essential back support is provided with the help of the Ultimate Edge Foam Support Core. This core offers a superb combination of support and contouring, it's adjustable base compatible, and it helps minimize transfer of motion for undisturbed sleep. The edge support system ensures a consistent feel, even when sleeping to the edge.

To summarize, if you're searching for one of the firmest single sleeper mattresses available in the iComfort line, the Cal King Serta iComfort Blue 300 Firm Mattress may be the perfect match for you. This mattress is dependably built, and it comes backed by a 10-year warranty.
