YES YS-88 High Back
The Office Master YES YS-88 is the high-back chair in the YES range, a 24" tall mesh back over a wider, cushioned upholstered seat. It is the model to specify for taller sitters, for long days, and for anyone who wants support that carries up behind the shoulder blades rather than stopping at the mid-back.
Height alone would not be enough, so the YS-88 pairs it with OM's Full Multi-Function (-8b) mechanism, the most adjustable in the YES line-up. Back angle and seat angle are set independently, the back adjusts for height, the seat slides for depth, and the seat tilts infinitely forward for perching or for relief at a keyboard. On a back this size that independence matters: it lets the sitter open the torso angle without the seat following it.
