With clean, classic aesthetics and smart ergonomics, Amia earns its keep as a versatile chair that works –anywhere. Ama's LiveLumbar flexor system, hidden in the backrest of the upholstered model, changes shape to support your entire spine in its natural, healthy S-shape. Amia’s arms adjust through a full range of motion – 360 degrees – for support that follows you as you work with multiple tech devices and interfaces. Armrests are designed to remain parallel to your work surface as you move, so you can stay comfortably on task at every angle of recline. Features include adjustable seat depth, fully adjustable arms, adjustable lumbar, seat height adjustment, recline tension adjustment, upright back lock, upholstered back and seat, and wheels for carpet flooring. Arrives fully assembled and is backed by a 12 year warranty.
