Our Verdict

Novaform Serafina Pearl

Casper Cooling Select

The Casper Cooling Select is a better mattress than the Novaform Serafina Pearl. Both are medium all-foam mattresses, but the Casper offers better performance in a few areas. It's slightly more cooling, though neither option is quite cooling enough for hot sleepers. It's also more responsive, so it's easier to move around on. And it does a better job of isolating motion, so you'll feel less movement across the mattress, making it a better choice if you're a light sleeper or if you sleep with a partner.
