There are many good styles of ergonomic chair and there are some things that are very important to look for in a good ergonomic office chair. These will allow the individual user to make the chair work well for their requirements.
The best ergonomic chairs have adjustment movement, a movement that supports your body throughout the day, following your movements and protecting the curve of the spine and your posture. Whilst some people, for medical reasons, may not suit a chair with movement, the majority of people would benefit, whether or not they have an existing back problem. Buying an ergonomic chair should be about prevention, allowing good support and posture.
Office chair seat height should be easily adjustable. The Height adjustment lever is the easiest way to do this. The user should have his or her feet flat on the floor, or a footrest, with the shoulders relaxed and the pelvic angle in an open position.
The seat should have enough width and depth to support any user comfortably. The depth (from front to back of the seat) needs to be enough so that the user can sit with his or her back against the backrest of the ergonomic office chair while leaving approximately 5cm between the back of the knees and the seat of the chair. The forward or backward tilt of the seat should be adjustable.
Lower back support in an ergonomic chair is very important. Sitting for long periods without lumbar support can lead to slouching (which flattens the natural curve) and strains the structures in the lower spine.
An ergonomic chair should have a good support and adjustment (both height and depth) so the user can have the proper support to the lower back.A backrest should be adjustable in height and in angle – although this is not always essential if the chair has a good movement in the mechanism. It should be able to support the natural curve of the spine, again with special attention paid to proper support of the lower back.
Are your armrests working? Armrests can support 1/5 of your body weight when seated. Office chair armrests should be adjustable. They should allow the user’s arms to rest comfortably and shoulders to be relaxed. The elbows and lower arms should rest lightly, and the forearm should not be on the armrest while typing. It is also very important that armrests do not conflict with the edge of the desk – most of our chairs are available with short, or retracting armrests to help prevent this.
