Headrest for Herman Miller Aeron Chair

Eliminate upper-back, shoulder and neck pain by adding this headrest to your Aeron chair. This headrest was specifically created to offer neck support while leaning back in your Aeron chair. This ergonomic accessory is a must for every avid Aeron owner. 'FreeFlow Motion' - A simple ergonomic concept which in principal keeps the Headrest's 'Up/Down' and 'Tilt' features loose. The pillow "floats" freely with every change in sitting position powered by shoulders and head movements. Rather than being fixed into a single position, 'FreeFlow Motion" keeps correct neck support moving with you. Easy 1-minute installation! (tool included) Important Notes: Made to fit the Herman-Miller Aeron chair ONLY. Color may not match every model perfectly. (Shown on Graphite chair). This headrest is NOT made by Herman Miller. Note: Unit will not "lock" into single position. "FreeFlow Motion" allows headrest to move and adjust along with shoulder and head movement. "Hassle-Free" Box contains: 1 Headrest unit, 1 hex-key tool, Assembly Instructions.
