Look for an ergonomic chair on wheels that swivels to avoid excess stretching and twisting of your spine and a five-point base won’t tip over when you recline. The tilt mechanism maintains support as you move and recline; it’s best to have your back slightly reclined while seated at your desk. The seat pan is the component of the chair that supports the majority of the user’s weight. Three or four fingers should fit between the seat pan’s front edge and the back of the knees. Tilt adjustments are preferred to allow for a forward working or reclined posture.
Ergonomic furniture in general and ergonomic desk chair in particular is tailor-made for comfort and ease. You will forget what pain is, once you start using ergonomic desk chairs. Ergonomic products are the best friends for your back and neck because they are designed keeping in mind your body and its contours. Ergonomic chairs keep your spinal chord straight and reduce your fatigue drastically. This, ultimately, enhances the productivity.
Armrests alleviate pressure on the back but can interfere with some lower desks. Tilt adjustments are preferred by most people to allow for a forward working or reclined posture. Almost all ergonomic task chairs come with a hydraulic seat height adjustment, which is probably the single most important adjustment mechanism on the chair. Three or four of your fingers should fit between the seat pan’s front edge and the back of the knees. The seat should always extend at least one inch from either side of the hips for optimum comfort because insufficient hip room can make you sit too far forward and not get enough support for the thighs. Adequate lumbar support is the most crucial element of the backrest.
Ergonomics therefore is a triangular relationship between the environment, the equipment and the human. There is no set formula; it remains the same in any environment that includes humans / machines, or equipment. My knowledge as an Occupational Therapist and my personal experience with a congenital back disorder and osteoarthritis in both hands, will guide you through correct principles for ergonomic performance and safety.
Ergonomics simply refers to the study of designing objects, like chairs, office chairs, keyboards, and workstations that are adapted to the form of the human body. It’s not likely you’ll find a really cheap ergonomic chair or cheap ergonomic office chair but you can find good quality low cost ergonomic chairs. Many times you can find them at a good discount. Some people spend thousands of dollars on new computers, and then buy a cheap chair from their furniture or office supply store, without giving a thought to their ergonomic health.
