Our Saddle Chairs and Stools allow for an ergonomic experience in environments where you need to "stay on your toes." The durable seat construction allows for rigorous use in most any environment. It has a one-touch seat height adjustment lever and a durable 5-leg 24" diameter fiberglass reinforced nylon base. The seat also tilts for added comfort. We’ve seen other stools fall apart almost out of the box. Bad welds, cheap casters, poor cylinders – they’ll do your stool 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 stool for many years to come. We promise to offer the very best quality and craftsmanship.
