Casper Snow

The Casper Snow is Casper's cooling-optimized all-foam mattress, built around the SnowTech cover and phase-change gel foam layers that target heat-displacement during sleep. Verified ratings show excellent cooling, motion isolation, and pressure relief — the three categories most relevant to its target buyer.

At a 5/10 firmness, the Snow is popular with side sleepers, couples, and hot sleepers who specifically want an all-foam construction. The phase-change material in the cover absorbs surface heat as the body warms it, which gives the mattress a measurable cooling-to-the-touch quality. Casper publishes a temperature differential claim for this; the underlying mechanism (phase-change gels with a high latent heat of fusion) is well-established in textile science. Casper's HeatDelete bands and zoned support layers, which date back to the original Casper, are retained.

For couples, the excellent motion isolation rating is consistent with the all-foam construction — the absence of coils means partner movement does not transfer across the mattress in the way a hybrid does. The 100-night trial is reasonable, and the 10-year warranty matches the category norm.

The limitations are around responsiveness and edge support. The Snow is all-foam, so it lacks the bounce and edge-out reinforcement that the Wave Hybrid Snow provides. Edge support is rated , which is a real consideration for sleepers who sit on the edge for dressing or who share a queen. The price ($2,295 Queen MSRP) signals the proprietary phase-change cooling system — for sleepers who don't strongly prioritize cooling, a less specialized foam mattress will deliver comparable pressure relief at a lower price.
