Every detail has a purpose. Designed to work well in a variety of spaces, these task chairs are ergonomically engineered to support users as they shift and move, without the use of complex manual adjustments. Innovative YouFit® technology delivers a personal fit with three distinct flex zones: the first zone fine-tunes the backrest to the curve of the spine to deliver constant lumbar support; the second calibrates the back angle during recline; and the third evenly distributes the user's pressure points to enhance comfort. These zones control the movement of the independent seat and back, and deliver continuous support to the user.
