Moderate use chairs are meant for people who spend half their working time at their desk and the other half moving around the building. The recommended moderate use chairs are the ones with a knee-tilt mechanism which allows users to lean back while their feet are rested on the floor. In chairs without knee-tilt mechanisms, the feet get lifted when the user leans back and this causes discomfort. Moderate use chairs possess more style than the commonplace task chair.
Just like the moderate use chairs, executive office chairs possess features such as the knee-tilt mechanism with the differences being that executive office chairs are bigger, have more comfort and possess more style due to the seniority of the user’s rank in the organisation. These kinds of chairs are designed with the busy executive in mind who usually shuttles between conference rooms and expends a good portion of his working time speaking on the telephone and typing on the computer keyboard. They are designed to offer comfort, style, and are status symbols as well. Most executive office chairs are high-back chairs.
In general when buying office chairs there are several conditions the office chair should meet for the user. It should be possible for the user to rest their feet comfortably on the ground and their thighs should receive full support. The user’s back should receive adequate and comfortable support so that the angle between their torso and their upper legs varies between a right angle and one hundred and five degrees. While it should be possible for the user to lean back, it should not be extremely easy. It is also important that the desk chair allows recurrent changes in posture.
