3156 Bariatric Task Chair: Built Bigger. Built Better. Meet the 3156—the heavyweight champion of 24/7 seating. Engineered to support up to 800 lb., this chair doesn’t just meet industry standards—it doubles them. Designed from the ground up for strength, comfort, and confidence, the 3156 sets a new bar in bariatric seating. Packed with ergonomic adjustments like tilt, seat depth, back angle, lumbar, and arm height, it’s built to keep users supported, aligned, and focused all shift long. And thanks to safety casters, the chair stays put when you sit down or stand up—no unexpected movement, just stability when it counts. With industrial-grade hardware (hello, Grade-8 bolts) and our Ergo Air Suspension System, you get full-body support and all-day comfort. And with a sleek design that matches the rest of the 3150 family, it blends seamlessly into any workspace. Backed by our full multishift warranty up to 800 lb., the 3156 is more than just a bariatric chair—it’s a durable, ergonomic solution that gets the job done.
