NapLab has put the Casper Snow Hybrid mattress with Heat Delete Bands to the test and rated it a 10/10 for cooling.
"The Casper Snow Hybrid has outstanding cooling performance. During our test, I felt no significant level of heat retention around my body."
"The mattress is equipped with a phase change material cover and also has a phase change coating sprayed on the top layer of foam. This material creates a notable cooling feel when you first lie on the mattress.
In addition, the hybrid design, high-quality foams, and limited 3.0” comfort foam layer are all having a positive impact on the cooling. The mattress also uses what Casper calls their “heat delete bands”."
In their tests, a max surface level temperature of 88.1° was measured, which is 1.47° cooler than average.
Based on our objective tests, subjective experience, and material analysis, I expect most sleepers will find the Snow Hybrid is exceptionally cool.
