If you work in an office or at home, chances are the majority of your time will be spent in front of a computer, typing away. This lifestyle can wreak havoc on your health due to people not thinking about their posture. Most people do not think about it, and end up regretting it somewhere down the line when its too late.
To prevent aches, pains and health problems in the future, its extremely important to maintain a good posture. Adoption of a good posture can be hard, but perseverance will slowly make it a natural thing to do.
People come in all different shapes and sizes, and so do office chairs. Having access to a chair that suits your size is extremely important. A decent sized chair for an individual should allow your feet to be placed firmly on the floor while keeping your knees level with your hips.
The next thing you should check your chair has arm rests. Spending a lot of time at the computer without resting your forearms can cause of a lot of discomfort before you know it.
Also, be sure to check that your chair back is high enough to support your whole back.
