4. Reclining


The optimal posture for the angle of the backrest (reclining) varies depending on the type of work, but the basic rule is to try to prevent your back from moving away from the backrest by leaning forward, and it is preferable to make sure your head is in line with your spine so that the weight is held properly.


When working with a computer, it is also important to avoid a downward-facing posture. The display should be at eye level, and if you are using a notebook PC, you can use a stand to elevate the display to reduce the burden on the body.


5. Seat Depth


The basic premise of how to sit in a chair is to sit deep in the seat. Sit deep in the seat, making sure your back is against the backrest, leaving no space in between. If your hips shift forward on their own, there is a high possibility that the chair is not best suited to your body and posture.


Most of the Okamura’s office chairs have seat depth adjustable function. Office chair can be adjusted back and forth, make a small gap between the front of the seat cushion and back of your knees so that about two fingers can fit. The tip of the seat should not hit the back of the knee or put pressure on the back of the thigh where large blood vessels run.


6. Armrest


An armrest supports your elbows and reduces the burden on your shoulders, especially if you use a computer keyboard. The keyboard should be placed in front of you so that you can operate it with your elbows resting on the armrest. At this time, adjust the height of the armrest so that your shoulders do not lift unnaturally. If you don't have an armrest, you can put your elbow on the desk.
