The Autonomous ErgoChair Ultra 2 is the most recent chair offering from Autonomous after years of making great chairs.
I have reviewed many of them, including the ErgoChair Pro, ErgoChair Mesh, several desks, and other items from Autonomous. They are known for high-quality gear, rivaling that of Herman Miller and other notoriously fabulous companies. These chairs are created with quality materials, and there is some evident care of quality and performance when designing and building these chairs.
