The highly complex intra-office power dynamic at the accounting firm of Adams, Fitzhugh & Associates shifted dramatically Tuesday, when a $229 Futura EZ-Roll office chair was delivered to the cubicle of Henry Rozema. The deluxe new chair, ordered to replace a broken one, stands a full two inches higher than that of co-worker Bill Kraft and, unlike Kraft's chair, features such options as a fingertip-controlled pneumatic height adjuster, customized swivel/tilt controls, a five-blade base with dual-wheel casters, and a leather-upholstered ergonomic backrest. 'This radically alters the elaborate, ongoing power struggle between Henry and Bill,' office manager Brenda Rutt said. 'As partner Willard Haines' retirement draws ever closer, Henry and Bill's desire to replace him only grows stronger, and this striking, option-packed piece of office furniture gives Henry a substantial psychological edge.'
