Ergonomic office chairs should help you to increase back and neck support and also help to improve your posture and help prevent slouching. Many employees of the office often experience back pain because they sit in their chair for extended periods of time. Doing this will increase stress in the spine, neck, arms, shoulders, and even the legs. By getting a chair that isn't ergonomically friendly, you could end up aggravating any existing conditions you may have.
The ergonomic chair you select should be an inch wider or more than your hips or thighs on both sides of the chair. The seat pan on the chair should be contoured for equal weight distribution and also to provide maximum comfort. You should also make sure that your back arches against the chair, as this will help to prevent slumping.
A helpful feature to ergonomic office chairs is the adjustable height mechanism. This can be a great essential for busy office meeting rooms or conference rooms where different people use the same chairs. Most chairs that offer teh height mechanism will also allow you to fine tune the back rest of the chair in all directions. If your chair doesn't have a back rest, you can simply use a pillow or cushion to support your lower back.
All in all, ergonomic office chairs are ideal for those who are at their desk extended periods of time. These chairs don't cost a lot of money either, yet they will provide you a lot in terms of comfort and support. If your office is in need of office chairs, the ergonomic chairs are definitely worth adding to your office.
