You sink into bed after a long, exhausting day. Your head rests on what’s marketed as a "cloud-like," "luxuriously soft" pillow. It feels comforting at first, but you wake up hours later with a stiff neck, feeling restless, or worse, wide awake. You toss and turn, trying to find that perfect spot, but it never seems to come. If this nightly struggle sounds familiar, you’re not alone. Millions of people invest in what they believe is a soft, comfortable pillow, only to find their sleep quality diminishing.
