It's important to get an office chair right. We often sit in one for hours at a time, and if it's not ergonomically designed, it can be a real pain. Designed to support you in comfort, this chair features a ventilated, mid-back design, so that your mid-to-upper back is well supported throughout the day, without getting too hot. The seat showcases a waterfall design, intended to remove pressure from your lower legs and improve circulation. With flip-up arms, a pneumatic level, and rolling caster wheels, it can be easily tailored to fit your desk and comfort.
