Make an effort to determine your correct height. Ensure that your feet are supported at a height suitable to your position in the chair when you are sitting upright. You should be able to rest your feet on the footrest without tilting the chair forward or having to stretch for the footrest. Alternatively, it should not be too high as this can which can lift the thighs off the seatpan of the chair.
