Buying an office chair may seem simple, but depending on your needs and your job, many models will fit better than others. The chair must contribute to the well-being of the staff to avoid a backache. But which criteria best fit your choice of chair?
Ergonomic office chair
A good office chair first offers a comfortable seat when you use it for 8 hours or more a day. The most common pains are in the lower back, neck, arms and hands. An ergonomic chair allows you to adjust the office chair for optimal seating comfort.
The sitting position
First of all, you can not forget that an ergonomic chair is not enough. The sitting position is also essential to avoid pain. Keep your back straight, put your feet on the floor (flat on the floor) and relax your shoulders.
An ergonomic chair allows you to recline the seat. Avoid tilting forward and favor a horizontal or slightly inclined position towards the back.
The armrests of an office chair are well adjusted when you have your back straight and you can relax your arms on the armrests at an angle of 90 degrees.
An ergonomic office chair allows you to adjust the backrest, often with a tilt function. The hollow of the lower back should be well supported and the backrest should fit the contours of the spine. The back should be slightly tilted back and the trunk angle should be 90 degrees or more.
The height of the chair is well adjusted when the feet are flat on the floor (or on a footrest) and the knees are at a 90 degree angle.
Relationship between desk and screen
The distance between the screen and the eyes should be the length of the arm from the sitting position. The right position for the keyboard is straight in front of the bust, about 10 cm from the edge of the desk. The armrests are at the same height as the desk. Make sure the top of the screen is at the same height as your eyes.
