We are all different, and it's very important to find a chair that is right for you.
Most people look for a chair that they think looks good. Because that is important, but I have a couple more tips about what you should be looking for in a new chair.
If you're often hot, a chair with a mesh backrest is perfect as it will keep you cool and comfortable during the day.
If you feel the cold, choose one with an upholstered backrest.
Another thing to bear in mind is that the armrests on the chair should be adjustable up and down to provide good support for your shoulders throughout the day.
You should also have a little bit of space between the front of the seat and the back of you your knee.
This helps to improve the blood circulation in your legs. The more adjustment features a chair has to offer, the better the chance that you'll find a position that suits you.
Good luck choosing your office chair.
