Our Verdict
Beautyrest Harmony Lux
Nectar Classic Hybrid
The Beautyrest Harmony Lux is a better mattress than the Nectar Classic Hybrid for most people. It's a much more responsive option, with better edge support. Shifting sleeping positions, getting in and out of bed, and sleeping near the edge of the mattress are all easier and more comfortable on the Beautyrest. It's also slightly more cooling, though they are more evenly matched in this regard—the Beautyrest keeps you cooler as you fall asleep, but the Nectar transfers more heat throughout the rest of the night. The Nectar also offers better motion isolation, which is important if you or your sleeping partner toss and turn.
