The Helix Twilight Luxe is similar in design to our favorite mattress ever, the Midnight Luxe. Both were actually made for side sleepers, but the Twilight Luxe has a firmer feel than the Midnight Luxe. That said, the mattress is not so firm that we side sleepers can't enjoy sleeping on it. I found myself sleeping comfortably on my side during my days of testing. It has six layers total, with one layer of coils, three layers of foam, plus base support and a pillow-top. You can choose between two pillow-top options, a breathable Tencel or a cooling material. I tested the Tencel option and found it to be plenty cool enough as I slept through the last few summer heat waves.，更多细节参见超级权重
