I am selling office master YS 72 chair. It's a great ergonomic design featuring adjustment in seat depth, seat tilt, back height. I bought it last month with additional features including DCS memory foam and Grade 5 fabric, original price including tax 434. I am selling it because I am not using it very often. (I spend most time in lab and not using chair at home a lot)
