Our Verdict
Novaform ComfortGrande Plus
Casper Cooling Select Hybrid
The Casper Cooling Select Hybrid is a better mattress than the Novaform ComfortGrande Plus for most people. While both mattresses offer decent support, the Casper provides more pressure relief, making it more comfortable for side sleepers. It's also more responsive, making it easier to change sleeping positions, and it offers more efficient cooling for hot sleepers. That said, if you sleep with a partner, you'll feel less of their movements on the Novaform, so it's a reasonable option for couples.
