67 per cent of all employees sit improperly. To sit properly, you need to observe a couple of simple rules of ergonomics.
Your feet should rest comfortably on the floor. The foot surface should form an angle of 90° with the lower leg. This is possible by adjusting seat height to identify the best sitting position for people of various height.
To allow unrestrained blood flow, the knees should form a slightly obtuse angle with the body. The position is possible thanks to a specially profiled seat with height adjustment.
Height-adjustable armrests should make it possible to achieve an obtuse angle between the forearm and the arm.
The backrest should be slightly tilted back (the angle between the trunk and the rest of the body should be greater than 90 degrees) to allow undisturbed functioning of internal organs.
To prevent leg numbness and pressure on the thigh surface, you should use the entire depth of the seat.
The back should be in contact with a specially profiled backrest at all times, thus helping to maintain the natural curvature of the spine.
Sitting in the same position for prolonged periods is not advisable. Such a practice causes excessive load on the body. You should, therefore, change your position while sitting at your desk as frequently as possible, by stretching out your legs, arching your back and swinging in your chair. Dynamic posture changes during work help take the load off your locomotor system.
