Emma Comfort Mattress Features and Benefits

Let's take a deeper look at the features of the Emma Comfort.

Mattress Layers

Fresh Air Comfort Cover

This mattress cover is made of a breathable 99% polyester and 1% elastane fabric. This material is very light and airy, but it's still soft to the touch, making it comfortable for you to lay on.

Airgocell Foam

This is where the name "Emma Comfort" comes from. Airgocell is a unique, patented material designed to help you stay cool while you're sleeping on your mattress. It's made of an open cell foam that allows air to easily flow through it, eliminating heat buildup so that you never have to sweat or sleep hot again.

Emma Comfort Mattress Layers

HRX Foam

Is the Emma Comfort's most luxurious foam. It has a pressure relieving memory foam feel, but it's made with an open cell structure to allow air to flow through for improved airflow and temperature regulation. This results in a cool sleeping surface, which will remain consistently comfortable all night long.

Mattress Firmness

We've rated this mattress a 7.5 out of 10.

That's on the firm side of medium. The Airgocell foam and HRX foam provide a nice balance between comfort and support. This gives you the best of both worlds, where you get to enjoy the feeling of memory foam without sinking into your mattress or slowly drifting off to sleep all night long.
