My Take on The Serta icomfort Blue 300 CT Firm Mattress

by Jed Harrington

The Serta iComfort Blue 300CT Firm is a great example of a rerelease done right. Serta built a solid product that excels at pressure point relief, body surface area coverage, and cooling, at a price point lower than the competition.

Firm Overall Comfort

The Blue 300CT has a very solid feel, but still provides good pressure relief. If you're a back sleeper and enjoy a firmer feel, this mattress is going to be a great way to go.

Serta Foam Support Core

The Serta Foam Core delivers solid support to the lower back while minimizing motion transfer and works very well with the memory foam comfort layers.

Superior Comfort Components

Deep Reaction Max Memory Foam and EverCool Fuze Gel Memory Foam work together to provide superior pressure relief, a firm level of comfort, and outstanding motion dampening for undisturbed sleep.

TempActive Touch Cover

The TempActive Touch Cover provides a cool to the touch feel that works well to regulate body temperature for a cooler night's sleep.

An Outstanding Premium Mattress

In the firm mattress category of premium mattress, it's hard to top the Blue 300CT Firm. In testing, this mattress scored extremely well for back sleepers and side sleepers of all body types. It feels solid, provides great pressure relief, sleeps cool, and has a great edge support. Everything you need to enjoy deep restful sleep.
