A comfortable position is essential to productivity during work or play. That’s why we've designed the Nitro Series with a durable steel frame, class-4 gas lift, and 5-star black base. Thanks to the high-density mould-shaping foam, the chair will keep you engaged at all times. Use the 2D adjustable armrests to find the arm position of your liking or recline all the way back to 180 degrees if you need to rest a bit during a long day. It’s also got a tilt lock for when you find just the right angle. You can guarantee you’ll be supported with the included head and lumbar support cushions, too.
