The Industrial Work line of chairs from Perch Chairs & Stools is specifically built to withstand the rigors of industrial environments such as high velocity impacts, exposure to extreme hot and cold, and continual vibrations. These durable industrial polyurethane chairs offer total body support with advanced ergonomic features that improve productivity and reduce fatigue. The ergonomically contoured waterfall seat and back were designed to improve posture, circulation and comfort. These industrial polyurethane chairs feature an Ease Adjust System which allows you to adjust the pneumatic height and lumbar back support from a seated position. The lumbar support adjusts 4 ways – up, down, forward, and back for a personalized and posture correct fit. 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 many years to come. We promise to offer the very best quality and craftsmanship.
