CNET's Sleep Experts Test Casper Snow Hybrid Mattress: A Comprehensive Review A couple from CNET's team recently spent 30 nights testing the Casper Snow Hybrid mattress, sharing their comprehensive review. The duo, Dillon and [Author], found that the mattress excelled in motion isolation, density of memory foam, and cooling technology. However, they concluded that it wasn't the perfect fit due to incompatible firmness levels. The couple used CNET's proprietary Mattress Smasher 9000 device to objectively test the mattress' firmness level, which came out to be a 5 out of 10 - slightly softer than expected. They highlighted the importance of considering individual preferences and sleeping positions when selecting a mattress.
