About the Casper Snow Mattress
The Casper Snow Mattress is a 12-inch cooling hybrid with a medium feel, rated 5 out of 10. Its three-part Snow Technology — a QuickCool cover, phase-change material in the comfort foam and three HeatDelete bands — is claimed by Casper to run about five degrees cooler than a Casper without the bands. Zoned Align foam is softer at the shoulders and firmer under the hips and lower back, and individually wrapped Flex coils add support, airflow and edge reinforcement. The best new price is $1,904 at Mattress Overstock Kentucky as of November 3, 2026, down from a recent high of $2,120 on November 2.
