Casper Snow Hybrid Mattress Review – Test Lab Ratings

The Snow Hybrid does an excellent job of preventing motion transfer. The pocketed coil support core is responsive and provides some bounce, but the memory foam comfort system absorbs that movement and restricts it from moving across the bed’s surface.

Our testers did notice a bit of motion transfer on the Snow Hybrid, but it was minimal, and all but the most sensitive sleepers should find this model’s motion isolation adequate.

The Snow Max is an even stronger contender in this category thanks to its third foam layer.

The Snow Hybrid’s zoned support, responsive coils, and memory foam combine to provide better than average pressure relief. The coils within the support core are able to move independently from one another and compress at different rates.

The memory foam resting above the coils has a three-zone system that adds support beneath your midsection to align your spine while cushioning pressure-prone areas.

Though the Snow Hybrid didn’t achieve a perfect score for pressure relief, many sleepers will find it comfortable and effective. For maximum relief, sleepers should consider the Snow Max – an extra foam layer earned this model an even higher rating from our team during pressure relief tests.

It’s tough to make a mattress that hugs your body without absorbing significant body heat, but the Snow Hybrid manages to rise to the occasion. This model has multiple foam layers but prevents substantial heat retention by layering the foam atop an airy pocketed coil support core and incorporating proprietary cooling technology.

Memory foam conforms closely, and as a result, it has a tendency to trap heat. To combat this issue, this model’s memory foam layer includes phase change material and patented HeatDelete graphite bands, both of which are designed to draw heat away from your body.

Our testing team found that this model regulates temperature well enough to be a worthwhile choice for all but the hottest sleepers, who may prefer a model that substitutes latex for memory foam.

Although the Snow Max contains more foam and should, at least in theory, sleep warmer than the Snow Hybrid, we found this isn’t the case — the opposite, in fact. The third foam layer’s airflow channels do a good job of promoting circulation throughout the comfort system.

Though it has a foam perimeter reinforcement, the Snow Hybrid only achieved average scores during edge support testing in our lab. We found the foam isn’t firm enough to keep the edges rigid with direct pressure application.

People who need added support to get in and out of bed might want to look for a model that uses coil reinforcement rather than foam.

The Snow Max sank more than the Snow Hybrid during our edge support tests. This can be attributed to the Max’s softer feel.

Our testers found the Snow Hybrid somewhat easy to move around on. The memory foam relieves pressure while the pocketed coil support core prevents sleepers from feeling like they’re sinking into the mattress to an excessive extent. Testers found the Snow Max more difficult to move on, owing to the additional foam layer.

Beds that score highly in both our ease of movement and motion isolation categories are hard to come by, as these two characteristics are tricky to balance. The Snow Hybrid achieves this balance better than the Snow Max.

Casper uses CertiPUR-US-certified foams that have low volatile organic compound (VOC) levels in the Snow Hybrid and Snow Max. However, when you set up these mattresses, you may notice a smell as they expands to their full size. The scent is strongest when you first unwrap the mattress and dissipates with time. We recommend unwrapping your mattress in a room with plenty of airflow and waiting at least 24 hours before use.
