The cooling Muse mattress is made up of three layers of memory foam to provide comfort and support as well as pressure relief. The product engineers at Muse Sleep spent years testing different foam densities and variations to find the perfect combination.

Unlike other mattress companies, Muse didn’t stop at just one mattress. By altering the middle layer of foam, our engineers created three firmness levels, a soft, medium, and firm. Each firmness level uses different densities of foam and impression load deflection (ILD) values to give each one a unique feel.

The majority of Americans prefer the feel of visco elastic memory foam over other innerspring and latex mattresses. All the layers of the Muse mattress are visco elastic memory foam. This type of foam isolates motion, contours to your body, and provides pressure relief.

However, while most people like the feel, they don’t like that memory foam sleeps hot. In a traditional foam mattress, the heat gets trapped causing you to heat up and even sweat throughout the night.

Diamond Breeze Cooling Cover

To combat this, Muse uses a proprietary textile called Diamond Breeze fabric. The fabric is woven using temperature control yarns to create a phase-change material that absorbs ambient temperature, allowing you to sleep cool.

The cover feels cool to the touch and works to wick away moisture from your body, allowing you to wake up dry and refreshed. The Diamond Breeze cover zips on and off the mattress for easy removal and cleaning.

Layer 1: Temperature-Regulating Gel Foam

Beneath the cooling cover is the top layer of the mattress, the Temperature-Regulating Gel Foam. The first layer is made from two inches of four lbs. density gel-infused memory foam. The high-density memory foam keeps your body from sinking into the mattress, avoiding the dreaded feeling of quicksand.

The gel memory foam layer and the cooling cover work together to create the coolest mattress on the market. It’s a difference you can feel.

Layer 2: Responsive Comfort Layer

To meet the needs of back sleepers, side sleepers, stomach sleepers, and multi-position sleepers, the second layer of foam, called the Responsive Comfort Layer, differs depending on the comfort level you select.

The soft and medium firmness both include two inches of three lbs. density memory foam. The firm consists of two inches of two and one-third lbs. density memory foam. In addition to altering densities, the ILD of each layer varies to create a softer or firmer feel.

Mattress firmness scales are used to help people understand the difference between a soft, medium, or firm mattress. Muse rates its soft as a five out of ten; its medium as a six and a half; and its firm as an eight on a scale where one is the softest and ten is the firmest.

While a firmness scale helps to understand the difference between each mattress, our Mattress Quiz can recommend a mattress for you. All you have to do is answer a few brief questions to uncover the best firmness for your body type and sleep position.

Layer 3: Supportive Foundation

The third and final layer of the Muse mattress is the Supportive Foundation. It’s eight-inches of two lbs. density base foam that creates a durable, supportive layer. The solid foundation caters to all sleep positions and prevents the mattress from sagging. A bed that sags unevenly in the middle is often so uncomfortable that you have to replace it.

A firm foundation of support foam is also critical for avoiding pressure points. Pressure points are created when your hips or shoulders sink down into the mattress, pushing your back out of alignment. If your bed is too soft or too firm, you’ll wake up in the morning in pain.

When choosing a mattress, it’s important to understand the construction so that you know you’re buying a bed that will last and, most importantly, give you a good night’s rest.
