You are cracking it because it never stays fixed.\u003c\/h2\u003e\n\u003cp\u003eYou push on the joint. You get the sound. Two minutes later the pressure is rebuilding, and by mid-afternoon you are doing it again at your desk, in the car, in front of people who visibly wish you wouldn't.\u003c\/p\u003e\n\u003cp\u003eAnd it is worst in the morning. You wake up stiff, and it takes the better part of an hour before you feel like yourself.\u003c\/p\u003e\n\u003ch2\u003eThe urge is a daytime symptom. The cause happens while you sleep.\u003c\/h2\u003e\n\u003cp\u003eFor six or seven hours a night, the full weight of your head loads your neck. If the pillow under it holds the correct position for twenty minutes and then gives up, your neck spends the rest of the night sitting off position.\u003c\/p\u003e\n\u003cp\u003eThat is the stiff morning. And that is why the urge builds through the following day — your body is asking to be reset, because the position was lost hours ago.\u003c\/p\u003e\n\u003ch2\u003eYou have binned four pillows. Here is what actually went wrong.\u003c\/h2\u003e\n\u003cp\u003eEvery pillow sells you the position it puts your neck in. Not one of them sells you how long it \u003cem\u003eholds\u003c\/em\u003e it. That is the entire reason the pillow graveyard exists — the memory foam that was perfect for a fortnight, the expensive one, the firm one that was right on your back and wrong the second you rolled over.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory foam\u003c\/strong\u003e — correct at lights-out, bottomed out by 3am.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeather and cheap foam\u003c\/strong\u003e — no height memory at all.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirm orthopaedic\u003c\/strong\u003e — holds exactly one height, so it is wrong for half the night.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eThe mechanism: set, and hold.\u003c\/h2\u003e\n\u003cp\u003eCervaHold is built around two numbers you can check against the product in your hands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e8cm and 11cm.\u003c\/strong\u003e A dual-loft contour with a lower centre channel for back sleeping and raised outer wings for side sleeping — so the loft is correct whichever way you turn, instead of correct in one position and wrong in the other.
