there are many models, colors and styles of ergonomic computer chairs on the market today, with varying price ranges.
Regardless of the brand or price, there are some basic tenants that a good chair should have which are even endorsed by OSHA, the US government’s Occupational Safety & Health Administration The chair height must be adjustable.
The user should be able to sit comfortably with their feet resting flat on the floor or a foot rest.
A seat height that ranges from 16 to 21 inches is appropriate for most people.
The backrest should conform to the natural curvature of the user’s spine, and provide adequate lumbar support. Many chairs offer adjustable backs that move forward, backwards and tilt at different angles. In addition, a good chair offers the appropriate seat width and depth to support each user’s unique body shape and size. Armrests, if part of the chair design, should be adjustable so the user can rest their arms comfortably, close to their body, with their shoulders relaxed. When a user reaches to use their mouse, the armrest should not be an obstacle in their way. A chair on wheels/casters, that swivels and allows easy movement on the floor is also recommended. It also goes without saying that the chair overall should be comfortable and contain enough padding or cushioning for the user to sit for long periods of time.
