What the community says
Specialist reviews (BTOD) and user consensus place it among the most versatile Herman Millers for its dynamic backrest and adjustable seat depth. The most repeated criticism is one of taste: the polymer backrest isn't for everyone and those expecting classic mesh may be disappointed.
