Perch Polyurethane Lab Work Stool

The Polyurethane Lab Work line of stools from Perch Chairs & Stools is specifically designed for outstanding comfort and long-lasting use in the toughest workplace environments. These durable polyurethane stools offer exceptional support to improve productivity and reduce fatigue. The 13.5" polyurethane self-skinning, chemical- and puncture-resistant, and fully washable seat was designed to improve posture, circulation and comfort. These lab work polyurethane stools feature a 360° "All-Around" pneumatic height adjustment lever that allows you to quickly adjust the pneumatic stool height from anywhere you reach under the seat. Optional features include foot ring, and stationary caps. 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, and we guarantee it with a 15-year warranty on parts and a lifetime warranty on cylinders.
