Our Verdict

Saatva Classic (Luxury Firm)

Casper Cooling Select Hybrid

The Casper Cooling Select Hybrid is a better mattress than the Saatva Classic (Luxury Firm). It provides better support and pressure relief, making it a more comfortable option for a range of body types and sleeping positions. The Casper is also a better choice for couples; its effective motion isolation means that movement is less likely to wake you. It's also more cooling, so it's a good choice for hot sleepers. And while it's not the most durable mattress out there, its denser foam layers should help it resist sagging and indents longer than the Saatva.
