Short answer: The raised side wings are specifically designed to fill the anatomical gap between shoulder and ear, preventing the hunched-shoulder feeling common with flat pillows.
Why side sleepers are named the "best fit," not just "a fit"
Of the three sleep positions covered, side sleepers get the strongest, most direct endorsement — a specific, honest ranking rather than a vague "works for everyone" claim.
What the anatomical gap the wings address actually is
Between shoulder and ear is the specific space a flat pillow leaves unsupported — the raised wings fill this gap directly, rather than relying on loft alone.
💡 Worth knowing: the nose-to-chest test is a quick way to sanity-check whether the wing height genuinely suits your build once your pillow arrives.
