Our Verdict

Nectar Premier Copper

Novaform ComfortGrande Plus

The Nectar Premier Copper and the Novaform ComfortGrande Plus are fairly well-matched foam mattresses. You may prefer either, depending on what's most important to you. The medium-plush Nectar has better responsiveness and edge support, making it easier to move around and get in and out of bed. The medium-firm Novaform, on the other hand, offers better motion isolation and keeps you cooler, making it a better choice if cooling is a priority for you or if you're a light sleeper.
