Our Verdict
Nectar Classic
Novaform Serafina Pearl
The Novaform Serafina Pearl is better for most people than the Nectar Classic. The Novaform is much more cooling, so it can keep most people comfortable, and it's much more responsive, so it's easier to move around in your sleep. Its edge support is also better. The Nectar Classic is a firmer mattress, however.
