Adapts to your every move with an auto-tracking lumbar system.

Up, down, forward, back, pivot side to side and flip up — set them for typing, lounging or deep work.

Five recline angles up to 140°, with tension that adjusts itself to your body weight.

The seat rises to 21.6 in, giving taller users more leg room and better alignment.

The lumbar pad follows your spine with up to 3.5 in of front-to-back travel, supporting you as you lean in or back.

Seven positions across 2 in match the backrest to your torso, from petite to tall.

The lumbar pad pivots through 28° to stay against your lower back as you lean in or sit back.

Seat, backrest and arms all adjust to fit users from 5'0" to 6'3", upright or reclined.
