Our Verdict
Nectar Premier
Novaform Serafina Pearl
The Nectar Premier offers a slightly better sleeping experience than the Novaform Serafina Pearl. The Nectar is a bit more cooling, making it more suitable for hot sleepers, and offers better motion dissipation, so you're less likely to be disturbed by your partner's movements. Its higher responsiveness and bounciness also make it feel easier to move around on. On the other hand, the Novaform has better edge support, which is a plus if you prefer to sleep near the side of the bed, although it doesn't perform exceptionally well in this regard. You'll also sink more deeply into the Novaform's upper layers, so you might prefer it if you want a slightly more enveloping feel.
