For active sitting — at home, at work, or in game.

Phantom 4 Series is here with our first dynamic auto-tracking lumbar design and more ways to customize your support to help you sit better, move freely, and support a more comfortable sitting posture throughout the day.

Dynamic Auto-Tracking Lumbar

Engineered with a motion-responsive lumbar mechanism, The lumbar support of Phantom 4 Series can be extended forward with 15 locking positions across a 0–3.7 in mm range. In extended positions, the lumbar swivels 5° left or right and tilts 25° forward or back for personalized support.
