Our Verdict

Purple RestorePlus Hybrid

Casper Snow Max

The Casper Snow Max is a better mattress than the Purple RestorePlus Hybrid for most people. The Casper provides better support and motion isolation, which makes it a more comfortable option for most sleepers. In particular, it's a better option for couples, thanks to its excellent motion dissipation. That said, the Purple is even more cooling than the Casper, and it's bouncier and more responsive, which makes it easier to move around on.
