4C'S BUYING GUIDE
Each of our mattresses is evaluated using the 4C rating system to help you find the ideal mattress based on your preferences and needs. For detailed ratings, please visit each product page or refer to our Diamond Mattress Buying Guide.
Comfort
Comfort is a personal preference. Comfort of a mattress can vary from person to person based on size and weight distribution, along with sleeping position.
COOLING
Lowering the body’s core temperature promotes a deeper, more rejuvenative sleep. Some mattresses are designed to be cooler throughout the night.
CONFORMANCE
The support of a mattress will determine how it works to properly align the body into an ergonomic position to prevent aches and pains.
CORE SUPPORT
Core support in a mattress ensures proper spinal alignment and distributes body weight evenly, enhancing comfort and reducing pressure points for a restful sleep.
