Our Verdict

Casper Cooling Select Hybrid

Casper Snow Max

The Casper Snow Max is a better bet than the Casper Cooling Select Hybrid for most people. The Snow Max offers more support and pressure relief, making it more comfortable for a range of sleepers. It's also more cooling, and it dissipates motion more effectively, so it's a better choice for hot sleepers and partnered sleepers. That said, if you're shopping on a budget, the Cooling Select Hybrid is still decently comfortable for most sleepers, and it's more responsive, making it easier to move around and shift sleeping positions. It's also a little more durable, which is especially welcome at its much lower price.
