I work from home seven days a week. All of my work is done sitting in front of a computer screen and keyboard. I love my job but some aspects of it can be quite painful, especially my back and shoulders, from sitting in an uncomfortable chair all day. My current chair just does not seem to fit my body right. There is no lumbar support and my legs rest at strange angles for most of the day. I really think that I need to look into buying an Ergonomic office chair. I went to a store and sat in Ergonomic office chair and I think that they are very comfortable. My back actually feels like it would have the support I need to make it through the day without being in a lot of pain later. I might just have to go back and get one of these chairs.
