Your workstation must conform to you if it is to work to your advantage, and not the other way around. You need consistency in where the computer is placed, as well as where your hands and feet are to be positioned when working. Your computer chair is also a very significant aspect of making your workstation as appropriate for you as possible.
First, you need to decide upon the surface height of your desk. Will you be standing most of the time, sitting or doing a bit of both? The height of the workstation is contingent on the job you are doing, as well as your own height.
The seat of your computer chair should be such that the work surface is as high as your elbows. You should be able to fit a person's fist behind the calf and extend it to the front of the edge of the chair. This prevents the legs from being pressed more than they should be, and it helps to prevent the feet from swelling. While sitting at your chair, you should be able to slip two fingers under both of your thighs without a problem. As far as the backrest of the chair is concerned, it should push the low back forward ever so slightly. If these requirements are not met, then a different type of chair is required.
The height of the computer screen plays a role in office comfort too. Sit down in your computer chair and close your eyes, allowing yourself to relax. Once you have, and then slowly open your eyes. The spot where your eyes automatically look to upon opening is where the center of the computer screen should be placed. If necessary, raise the computer screen using books or some type of stand.
By ensuring that your workstation is healthy for you, along with applying various desk stretches throughout the day, your body will thank you!
