Here's what no one tells you: the average pillow is a one-size-fits-all rectangle that starts breaking down within months. It goes flat. Your head sinks. Your neck bends at an angle it was never meant to hold - for seven or eight hours, night after night.
So you wake with a stiff neck. A dull ache between the shoulders. A lower back that takes twenty minutes to loosen up. You blame your age, your mattress, "sleeping funny."
But the culprit has been under your head the whole time.
You've probably already tried to fix it. The firm memory-foam block that felt like sleeping on a brick. The "luxury" down one that's now flat as a pancake. The supermarket two-pack you replace every few months. None of them worked - because none of them do the one thing your neck actually needs: stay supported and aligned, whichever way you sleep.
