This is an important consideration for couples, as poor motion isolation can mean disturbing your sleep partner when you change sleep positions or get in and out of bed. Motion isolation refers to how well a mattress limits the transfer of movement from one side of the bed to the other. However, the gridded design of Purple’s top comfort layer contains air channels designed to improve airflow, prevent heat retention, and keep you cool as you sleep. Some foam materials have a tendency to absorb and retain body heat.

The Purple Mattress goes above and beyond many other all-foam mattresses with its excellent temperature neutrality. Purple’s unique GelFlex Grid comfort layer does a very good job of cradling the curves of your body while remaining supportive and promoting proper spinal alignment. Like most all-foam mattresses, the Purple Mattress offers ample pressure relief.

Pressure relief refers to how well a bed cushions your body and relieves tension from key pressure points. We score each category using a five-point scale from poor to excellent to help you choose the right mattress. Our team of sleep experts personally tests each mattress we review using a strict product testing methodology across a wide range of categories to capture how a bed will perform under real-world conditions. On the other hand, stomach sleepers who weigh more may need a firmer bed with added support. The Purple Mattress provided excellent comfort and support for our testers who sleep on their stomachs and weigh less than 130 pounds.
