What is the point of having a hydraulic height adjustment on an ergonomic office chair if the seat position is fixed so much so that a person's knees are bumping against the modesty panel of their desk?

People are all constructed differently and that is why quality office chairs such as this Ergobrain medium back office chair are the perfect solution for day to day long-term office work station comfort.  With its sliding seat feature and adjustable width and height for armrests, this chair can be set up to accommodate almost any physique.
