The sofa looks so inviting and comfortable, it beckons you as you’re attempting to focus on your work in your new home-office. So, what’s wrong with just sitting on the sofa while you work?
The problem is that using the sofa for office seating rarely provides a good fit in proper alignment or neutral postures. Prolonged sitting without sufficient support or in misaligned postures can place significant stress on your entire musculoskeletal system and set you up for discomfort that increases the longer you spend in this configuration.
Remember that short term comfort does not always lead to long term health. So, find a chair with back support for improved fit and seated postures while working at home.
