The Casper Slate is a 10.5-inch all-foam mattress with a medium-firm feel that balances support and pressure relief. It pairs a memory foam layer with a breathable soft-knit cover to help manage heat, and the foam is CertiPUR-US certified. It suits back and stomach sleepers and couples who want motion isolation, though side sleepers who like a soft bed and anyone who needs strong edge support should look at a hybrid instead.

Owners generally appreciate the Slate for its firm support that doesn't feel like a hard board, though some note it takes a few days to fully expand. It is frequently cited for helping with lower back pain.
