This is Casper's California King sleep set: the Snow mattress, an adjustable base and a waterproof protector, sold together. The Snow mattress is Casper's hybrid with a cooling cover and pocketed coils, and the adjustable base lets you raise the head and feet. At $4,598.10 at Casper as of November 5, 2026, it is the only new price listed, so there is no recent range to compare it against. The bundle costs far more than the mattress alone, so most of the premium is the adjustable base and the matched protector.
