It’s also available in a variety of colors and styles to suit any room. No more jockeying for the right position to reach the seat lever. The ergonomically contoured waterfall seat was designed to improve circulation and comfort. With the "EaseAdjust" system at its core you can quickly and easily spin, raise or lower the seat; as well as adjust the lumbar back support up, down, forward and back. And we don’t skimp on comfort, either: 3 inches of foam separate you from the supportive base of the chair. We’ve seen other chairs fall apart almost out of the box. Bad welds, cheap casters, poor cylinders – they’ll do your chair in quickly. That’s why we place so much importance on build quality. This model employs reinforced fiberglass nylon and steel to make sure you can trust your chair for years to come.
