Perch Lab Chair with Large Back

This line of medical chairs with large back from Perch Chairs & Stools offers extraordinary durability and excellent comfort for anyone in the medical field. 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, lower or tilt (optional) the seat; as well as adjust the lumbar back support up, down, forward and back. The stationary model enables you to direct all of your attention to tasks requiring extra attention to detail. 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. We promise to offer the very best quality and craftsmanship, and we guarantee it with a 15-year warranty on parts and a lifetime warranty on cylinders.
