More Frequently Asked QuestionsWhat are the height and weight limits for the AndaSeat Phantom 4?
Available in size L, Phantom 4 Series gaming chair is recommended for users up to 185 cm (6'1") tall and up to 100 kg (220 lbs).

How does the dynamic auto-tracking lumbar work?
The Phantom 4's dynamic auto-tracking lumbar system automatically adapts to your movement to provide continuous lower-back support.
Beneath the lumbar padding is a motion-responsive mechanism that allows you to pull the bottom edge to extend the lumbar into 15 different locking positions, with an adjustment range of 0–95 mm.
Once extended, the lumbar support responds to your body as you lean back — swiveling up to 5° left or right and tilting up to 25° forward or backward. This multi-directional movement helps maintain consistent spinal alignment as you shift, recline, or adjust your posture.
