Is an adjustable headrest worth it on an ergonomic chair?

Headrest specification at OfficeFurniture2go.com is application-driven. Adjustable headrests are specified for review, reading, and extended call postures. Fixed headrests are not specified for commercial task chairs — they push the head forward at standard monitor heights. We specify adjustable (height and angle) headrests only. Call 1-800-460-0858.
