From the first days of life, we are taught that we should only sit up straight – because it’s better for health, and it’s more productive to work in this position. But in reality, of course, this is not the case.

At first glance, working at a computer seems to be a very easy task. In reality, everything is exactly the opposite – this is a great test for the human body, which has not yet got used (and is unlikely to soon get used to) such activity.
Scientists have been talking about the dangers of a “straight back” when working at a PC since 2006 – but, as you know, we listen to anyone, except those who need to be listened to. So let’s say it again – sitting at the computer hunched over (less than 70 degrees) and with a straight back (90 degrees) is harmful!
How is it correct then?
The “correct” angle is 120 to 135 degrees. Simply put – like in a dentist’s chair. Sit back and have fun.
Picture to help:
A few more important points for those who want to sit correctly:
Lumbar support… The lower back has a natural inner curve. The lumbar support chair helps maintain this natural curve and prevents unnecessary stress.
Foot support… Ideally, they should be level on the floor. If your legs are not long enough for this, use a stand. This also reduces stress on the lower back.
Straight wrists… When typing, your wrists should be in a straight line with your arm up to the elbow. If they are unnaturally bent, prepare for painful problems like tunnel syndrome. Avoiding it is very simple – work on a laptop or, if you have a PC, buy an ergonomic keyboard with an extended wrist rest.
No armrests… With the correct table, chair height and the correct seating position, your elbows will be at a comfortable 90-degree angle. As a result, you, in principle, should not need to put them on the armrests. The latter only interfere – they always collide with the table (and provoke you to lower the chair and thereby set the wrong height), plus resting on the armrests negatively affects the shoulders and back.
Useful advice: If you sit at your computer a lot, you should consider buying a desk for standing (and ideally standing-sitting). Example 1 and example 2.
