Our Verdict

Novaform Serafina Pearl

Casper Snow

The Casper Snow is better than the Novaform Serafina Pearl for most people. The Casper offers significantly better motion isolation and cooling, making it a better choice for light sleepers and those who tend to sleep hot. That said, the Novaform has better edge support and a more responsive feel, so you're less likely to feel stuck in place.
