I use an office chair to use my desktop PC at home. However, I wonder whether this would be the best and most comfortable option, especially to avoid pain in the back. This is my current chair:
I wonder whether I should consider buying something else. I have read that gaming chairs are comfortable and appropriate for spending long hours in front of a computer. They are also very colorful, which is not very good as they may not go well with the rest of the furniture.
There are also some ergonomic chairs which I have seen and which are more subtle. I have read somewhere that gaming chairs are ergonomic, and other sources say that gaming and office chairs are not ergonomic at all, and that I should consider buying something more specific.
I need some advice. Should I keep my current chair as it is ergonomic (I do not think so, though)? Is a gaming chair as good as any other ergonomic chair, just more colorful? What should I pay attention to when buying a chair?
Thanks.
