Shoulder And Neck Strain
There is a good chance that the chair you had been sitting in at the office was comfortable enough for you not to end up with too much shoulder and neck strain. However, the way you are sitting, and the type of seat you are sitting in at home can be a big contributor to this problem. You may want to raise your seat higher by putting a pillow or pillows on your seat so you are keeping the keyboard level at elbow height.
