TIME Magazine named the Herman Miller Equa 2 “Design Of The Decade, ” citing it as one of the best-ever ergonomically designed chairs. This one, in teal, is in superb condition. Designed by Aeron chair designers Bill Stumpf and Don Chadwick, this Equa 2 offers outstanding back support and comfort. The advanced technology of the chair allows you to move around, perform tasks, and sit in a variety of positions in a one-piece shell with an H-shaped cut-out, waterfall edges, and replaceable foam cushions. It’s made to respond to and interact with you, without requiring you to manipulate levers or knobs. Please Note: This is the “Equa 2″ model. The original Equa is an outstanding chair. This model advanced the patented Herman Miller innovative technology even further. Most notably, this version features an adjustable lumbar pump, allowing you to truly customize the lower back support. By adjusting the pump, you can fine-tune the chair’s lumbar curvature to match your comfort preferences. Whether you need more or less support, the lumbar pump ensures personalization. Comfortable, continuous back support from patented 1-piece shell. Height-adjustable and width-adjustable arms with super-comfortable thick padding. Biomechanical knee-tilt mechanism eliminates pressure points on underside of thighs as chair reclines, promoting healthy circulation. Patented built-in pump for lumbar support adjustability. H-shaped cutout allows air to circulate, relieving heat build-up. Thick, foam padding with waterfall edges won’t catch clothing. Super-stable 5-star base with ultra-durable casters. Pneumatic seat height adjustment. Width of seat: 20. Depth of seat: 19. Height of seat: Adjustable from 15.5″ to 21″. Priced at a fraction of the original cost, this is a true bargain. It may be the most comfortable chair you’ll ever sit in.
