Nectar Premier Adjusts To Your Sweaty, Freezing, Warm, Hot, Perfect, Whatever, Self.

While Nectar uses cooling materials in the cover, Nectar Premier builds on this by using ActiveCool memory foam, which dynamically adjusts to individual body heat. So if you sleep hot, it wicks your heat and stores it. If you sleep cool, it releases stored heat to help warm you. And with the Premier, you get the cooling cover, too. So you, or you both, or you all sleep even-steven and wake up like hibernation’s over. More Cradling And Contouring. Less Motion Transfer

Doze off even more dreamily with denser foam in Nectar Premier’s comfort layer. That means you can really find your sweet spot without waking your partner, while drifting off as snug-as-a-bug in a body hug.
