Our Verdict
Nectar Premier Copper
Nectar Classic
The Nectar Premier Copper is a better mattress than the Nectar Classic. Like most foam mattresses, both options provide great motion isolation, but the medium-plush Premier Copper outperforms the medium-firm Classic pretty significantly in every other area. Its biggest advantage is in responsiveness. The Premier Copper responds very quickly when you compress it, so it's much easier to move around and change sleeping positions. It has better edge support, too, so you don't feel like you might slip off the side, unlike with the Classic.
