How Should the Ergonomic Seat Be ?
Ergonomic seat is an extremely important feature for desk workers. Because we know that a correct posture while working at the desk is very important to protect the musculoskeletal system from problems such as contracture and discopathy, as well as to feel more comfortable during the hours spent at the desk and therefore to do the job better.
It is important to have an ergonomic chair to achieve good results. An ergonomic work chair has standard numerical parameters, specific dimensions, height, width, etc. respects... But these are of course dependent on the person using it, and it is therefore advisable to take into account the specificity of each and adapt these parameters to the situation.
Basically, to make an ergonomic chair functional, you will need to choose it according to your physical build. The chair needs to be adjusted as we are not all the same. Adjustment controls should be accessible and easy to use while seated. We usually find them under the seat.
How exactly should the chair be set up ?
The chair should be best calibrated to your body. This includes adjusting the seat, armrests, and backrest. The seat is at the correct height when the upper and lower legs are at right angles and the feet are flat on the floor, together. its entire surface should be filled. Then your entire back should be against the backrest.
How to Sit Correctly ?
The tilt of the pelvis is directly related to the support of the spine. While walking or standing, the pelvis should be at the same angle. This provides good support for the spine. An office chair with a forward - bent seating surface while supporting the backrest will keep the spine in a natural double S shape.
Step 1: We adjust the seat height
Ergonomic seat should be height adjustable and match the forearm top to bring the angle from the knees to 90-110. The lift of the seat ranges from a minimum of 39 cm for a height of 1.45 m to 55 cm for a height of 2.05 m.
Feet should be placed on the ground and also rest on great support when needed.
Step m 2: We position the pelvis correctly
To sit correctly, it is necessary to bring the pelvis back as much as possible by leaning on the backrest to dissipate some of the forces from the spine.
Step m 3: Let's adjust the backrest
The back of the work chair plays a very important role, so it must meet multiple requirements and be adjustable in various ways.
As for the features, the backrest should:
• Have a semi-rigid fill and a breathable lining
• It is of medium height and provides lumbar support, better if its height can be adjusted. Height adjustment is made by placing the hands on the base of the backrest and moving them upwards. In this way, it is possible to position the lumbar support exactly in accordance with the lumbar curve of your back.
• Be adjustable in inclination by means of a special lever that blocks and unlocks the swing of the backrest and fix it at the most comfortable inclination for the torso, between 90 ° and 110° relative to the thighs
• In summary, the basic angles that must be followed in order to get a correct posture are those that must be greater than 90 ° at elbow, hip and leg alignment, are suitable for muscle lengths, and do not prevent lymphatic blood circulation.
• Also, great attention should be paid to the shoulders, which must remain relaxed when the hands are typing on the keyboard, using the museum, or when the forearms are resting on the table or armrests.
• Ergonomists remind that the spine suffers from prolonged positions in any case, so it is better to avoid sitting for more than 30 minutes, and it is imperative to change positions frequently even while sitting. Therefore, besides choosing an ergonomic seat, it is useful to have a modern sitting desk for maximum comfort.
