Let’s start with the pillow itself. “If your pillow is too high, then your head will be propped up too high also, bending the neck, which presses the chin against the chest,” explains Stalina Glot, Senior Esthetician at Haven Spa in NYC. “The muscle fibers will tighten, which delays lymphatic fluid to drain properly throughout the body,” she explains. To that end, the Night Pillow was engineered to promote restorative sleep, thanks to a self-adjusting, hypoallergenic memory foam that is lighter, airier, and fluffier than anything on the market—without being overly bulky. The custom-fit silk pillowcase creates optimal moisture levels for your skin and hair—minimizing bed head and hair breakage and promoting clean, hydrated skin. Plus, the signature black hue negates light, acting like a built-in sleep mask. To reap the benefits of the Night Pillow, however, you must not cover it with a separate pillow case, and you should wash it in its special mesh bag.
