Feast your eyes on what may be the most advanced office chair ever conceived. Produced by Herman Miller, the Embody Chair ($1,600) is the successor to the Aeron Chair which claims to improve lower body circulation, mind-body connection and office productivity. Embody targets the wiggly worker who lives with laptops, flat-screens and wireless devices. Embody is the last design from the late Bill Stumpf, who created or co-designed the Aeron, Ergon, and Equa work chairs. His legacy led to his reputation as the father of modern ergonomic seating. In 2002, Stumpf told Herman Miller: “I think I have one more in me.” Inspired by a uniquely comfortable pair of shoes, Stumpf pursued the new chair design with protégé and partner Jeff Weber. After Stumpf died in 2006, Weber, 45, evolved the design at his Minneapolis-based Studio Weber & Associates. One significant feature of the new chair is an exposed spine-like flexing structure for the backrest. The back moves with 56 flexors to support the occupant, and the seat cushion is topped with 93 connected plastic discs, or pixels, to move as the sitter moves. Other facets, including a backrest narrowed at the top and extendible depth for the seat, give laptop and keyboard users more freedom to move.
