Complete Serta iComfort Blue 100 Mattress Review

Serta’s iComfort Blue 100 Gentle Firm mattress is part of the popular Serta iComfort series.

It is recognized for its ability to provide adequate support, without sacrificing comfort or quality.

Evercool memory foam ensures that the mattress remains cool in the summer months, allowing for a more comfortable sleep.

The mattress is crafted in four different layers, each designed to provide benefits in terms of things like comfort, pressure relief, breathability and sufficient support for tired, achy muscles.

The mid-level, premium-grade mattress boasts 9.75 inches in thickness.

The top layer (aka the ‘comfort zone’) is created using ¾ inch TempActive Gel Memory Foam to better regulate core body temperature and to encourage a peaceful, comfortable full-night’s sleep.

Next, a 2-inch layer of EverCool Fuse Memory Foam provides maximum breathability and allows air to flow freely in order to eliminate heat build up.

Third, a 1-in layer of Serta Balanced Support Foam lifts and supports every curve of your body – resulting in a pain-free sleep.

Lastly, each layer is held up by 6 impressive inches of Serta Ultimate Foam Core to not only provide a superior base but also to increase the lifespan of the mattress.

What Type of Mattress is the Serta iComfort Blue 100?

The Serta iComfort Blue 100 Gentle Firm is the most basic of the iComfort line – but that doesn’t mean it is a ‘basic’ mattress.

Made using multiple layers of memory foam, it is suitable for both back sleepers and stomach sleepers alike.

Despite being a foam mattress, it is more firm than soft – but still contours to the body creating maximum snugness and support.

Like all other Serta iComfort mattresses, the Blue 100 Gentle Firm comes complete with a 120-day in-home trial period.

How Firm is the iComfort Blue 100 Mattress? Will I Get a Good Night’s Sleep?

The mattress is considered to be of ‘average’ firmness.

The benefit of having moderate firmness levels means that it is the ideal sleep solution for the largest variety of people.

Serta’s iComfort Blue 100 is created using four layers of modern foam technology to ensure a cool, comfortable sleep – every time.

This means that if you are prone to backaches, shift positions frequently throughout the night, or prefer to sleep on your back, you are guaranteed to wake feeling rested and refreshed.

What About Motion Transfer? Will I Wake My Partner if I Roll Over?

Gel Memory Foam and Fuze Memory Foam absorb motion transfer to isolate movement while regulating body temperatures.

This means that people who change positions frequently during the night won’t disturb their partner’s sleep.

It also means that people who have partners who give off body heat while they sleep don’t have to cuddle up next to the fan!

How are the iComfort Blue 100 Mattress Layers
