Anyone who works long hours sitting at a desk knows the benefits of a good ergonomic chair. A proper ergonomic chair helps you have good posture, improved circulation, and relieves strain on your back. It also helps you stay comfortable all day long.
Seat height. Ergonomic office chairs contain an adjustable seat feature. An adjustment lever enables you to adjust the seat height so that your feet will be flat on the floor and arms even with desk. Most office chairs seat heights range from 16 to 21 feet high.
A well-designed, ergonomic office chair enables the user to sit in a balanced and comfortable position for extended periods of time. But keep in mind that an office chair is only one component of an ergonomic workstation. Other factors, such as footrest, task lighting, and work desk need to be adjustable to be custom fit to the worker.
Seat depth and width. The majority of office chair seats are 17 to 20 inches wide, which supports most users comfortably. For an office chair to be ergonomic, the user should be able to sit with her back touching the backrest, while also having two to four inches between the seat of the chair and back of her knees. Backrest. An ergonomic office chair should have a backrest that is 12 to 19 inches in width. The backrest should have a forward or backward adjustable tilt.
Lumbar support. Lumbar support is essential to supporting the natural curve of the spine. Sitting for extended periods of time without proper lumbar support can cause slouching, which can lead to strains in the lower spine. An ergonomic chair should have an inward lumbar support curve. For even more of a custom fit, some ergonomic chairs allow you to adjust the lumbar support.
Seat construction. An often overlooked feature of an ergonomic chair is its seat material. The seat material should contain enough padding to be comfortable sitting for long periods of time, but also firm enough to offer support. The fabric should be comfortable for you too. Cloth and mesh are good examples of breathable seat fabrics.
Seat arms. Deciding whether you want a seat with or without arms is often a matter of preference or based upon the type of job you're doing. For instance, if your job requires you to be active or move around while seated, a chair with arms may get in the way. On the other hand, if you'll be spending a lot of time typing or having conversations with customers, clients, or employees, you may find a chair with arms will be a more comfortable way to spend your hours at work. Some ergonomic office chair seat arms are adjustable, which are helpful for computer operators. Seat arms come in varying widths, so be sure to choose the seat width that accommodates your preferences and tasks.
Stability. It goes without saying that a chair for be stable. Look for a five-point base as a sign of chair stability. Swivel. If you job requires you to get up and about from your chair or reach into your desk file drawers frequently, then a chair that swivels will be less taxing on your body.
