Everyone knows that people come in many different shapes and sizes. Before buying an office chair, there are a few questions that you should ask yourself. You should decide how you plan to use the chair, as this will be the determining factor for true comfort. Almost all office ahirs come with a variety of mechanisms that will control the tilting angle, tension tightness, and a mixture of other controls as well.

Heavy use chair

These types of chairs are for those who plan to sitting at their desk for long periods of time. If this is your profession, you should look for a chair with a tilting mechanism and also a fatigue reducing device on the bottom of the chair seat. Because of this device, moving forward or backward will enable the chair move with you in order to provide support. This will help to support your back at all times.

Moderate use chair

If you are a typical assistant manager or run back and forth between your desk and other areas throughout the day, you should consider getting an office chair with a knee-tilt mechanism. This allows you to lean back in the chair, yet still keep your feet firmly planted on the ground. Chairs that don't have this will typically lift your feet when you lean back and fort, which can ultimately lead to discomfort over time. Best of all, these chairs are normally more stylish than the average task chair.

Executive office chair

These types of office chairs normally have the same types of mechanical features as moderate use chairs, although they are normally larger, more comfortable, and offer more style for the executive. They are designed for the average executive who is busy running about and spends a good deal of time either on the phone or on a computer. Comfort, style, and status are the key features when buying one of these types of office chairs.

For the average security, an office chair that offers the ultimate in comfort is an ideal purchase. You can purchase a heavy use chair, as you'll probably spend a good amount of time at a desk. If you move around a bit, you may want to go with a moderate use chair, as it will provide the comfort you need when you return back to your desk.
