Short answer: Typically 3–7 nights of adjustment — a specific, disclosed timeline worth understanding before judging the pillow on night one.
Why the timeline is broken into three specific, named stages
Night 1 (unfamiliar firmness), Nights 2-6 (settling in), and Night 7+ (neutral position) — three distinct stages, not one vague "give it time" suggestion.

"First few nights felt odd, almost too firm. By night five my morning neck stiffness was noticeably gone" — Howard T.'s account directly reflects this stated, staged timeline.
💡 Worth knowing: reduced morning stiffness is the more commonly reported outcome by night seven and beyond, once the adjustment settles.
