Casper Snow Hybrid Mattress Review: Test Lab Ratings

“Both the Snow Hybrid and Snow Max were great at limiting vibrations from movement, so there’s only a minimal risk of sleep disturbances from motion on the other side of the bed.” – Logan

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

The Snow Max has an extra layer of memory foam, allowing it perform even better in this category. Overall, these mattresses are a solid choice for couples and people who have a pet or small child who frequently shares the bed with them.

“I was fully expecting to overheat on this mattress, but that wasn’t the case at all. I was able to sleep for hours at a cool temperature.” – Jeremy

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.

The Snow Hybrid’s memory foam layer includes phase change material and patented HeatDelete graphite bands, both of which are designed to draw warmth 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.

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. In fact, the third foam layer’s airflow channels do a good job of promoting circulation throughout the comfort system.

“Edge support on this mattress isn’t terrible, but it’s also far from a selling point. The softer edge didn’t bother me that much, but it might be a problem for heavier sleepers and people who spend a lot of time sitting on the edge of their bed.” – Logan

Edge support is one of the weaker points of the Snow Hybrid and Snow Max.

Though it has a foam perimeter reinforcement, the Snow Hybrid rated as below average during our edge support testing. We found that the foam isn’t firm enough to keep the edges rigid when heavier weight is applied to it.

People who need added support to get in and out of bed might want to look for a mattress that is firmer or made with a springier material for more robust edge support.

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

“I didn’t feel totally stuck in place on the Snow Hybrid, but there’s not much springiness to help you move around in bed.” – Jackson

Our testers found that the Snow Hybrid didn’t promote easy movement, but it also didn’t cause major barriers to moving around.

Although the memory foam contours around the body, the pocketed coils create a firm base that keeps you from feeling like you’re stuck in quicksand. Our team found that movement was a bit tougher on the plusher Snow Max.

For most people, ease of movement isn’t a make-or-break category, but it may be a priority for people who frequently switch between sleeping positions during the night and want to be able to do so without any resistance from their mattress.

“There’s a pretty strong smell when you first unbox the Snow Hybrid. I didn’t notice it after a few days, which is about par for the course for a hybrid mattress.” – Jeremy

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 expand to their full size. The scent should dissipate within a few days to a week.

If you are sensitive to smells, we recommend unwrapping your mattress in a room with plenty of ventilation and waiting at least 24 hours before use.
