The search for a good chair was not easy. Steelcase is good choice, It is ergonomic chair, livelumbar technology flexes with movements for ergonomic comfort, there are several color to choose. I've been using a Leap chair for nearly two years, and overall have been very pleased with it. I tested out Steelcase think, Steelcase Leap chair is more comfortable than other chairs, example Aeron. Main difference is that Leap is more flexible and comfortable in many positions, while Aeron is more rigid and you have to sit in a single position.
