The Voyage Office Chair in Black features a 100% polyester seat with a breathable backrest for all day comfort. The black plastic base has five casters for mobility and a synchro-tilt mechanism that reclines the back at a 2-to-1 ratio to the seat angle. Height-adjustable arms provide upper body and shoulder support. This modern office chair has a swiveling height-adjustable seat and is available in red. The arms can be left off during assembly or removed later if desired, but an armless version is also available.
