Office Chairs | Desk Chairs
Office chairs, or desk chairs, are adjustable chairs designed specifically for performing desk tasks. Typically designed with high degree of adjustability based on individual ergonomic preferences and the height and stature of the user, office chairs are usually capable of rotating a full 360 degrees, rolling on casters, and can adjust the heights of both the seat and the arms. Office chairs are further specialized for different office needs that range from task chairs for short term usage, mid-back chairs with greater back support, and executive chairs with full back and head support. High-end office chairs are ergonomically designed to comfortably support a user for longer periods of time.
Office chairs have wheels for a variety of reasons, but the most important reason is for the ease of mobility around the office without standing—a design feature originally implemented by Charles Darwin to move around his laboratory. Most office chairs today have five legs for improved stability when moving on the wheels.
Lumbar support in office chairs refers to the form of support given to the lower back. Lumbar support is built into the shape of the office chair and is designed to be pushed flush against the small of the back when sitting in order to keep the spine in natural alignment.
Desk chairs should be set to a height just below the height of your knee cap when standing. Setting your desk chair to this height allows your feet to be flat on the floor and your knees to be comfortably and ergonomically bent at a 90° angle.
