How to sit on ergonomic Chair Correctly?
Correct Posture:- Correct working posture Always sit back and move your chair close to the desk to maintain contact between your back and the seatback to help support and maintain the inward curve of the lumbar spine. This can easily be achieved by choosing a seat that has a forward tilt of 5°-15° thereby ensuring your hips are slightly higher than your knees.
Incorrect Posture:- Poor working posture Do not perch on the front of your seat. Do not place your keyboard too far away. Instead, move it closer to the front of the desk Avoid incorrect slouching where the angle of the pelvis rotates backwards. This results in the loss of the inward curve in the lumbar spine, causing excessive strain on the lumbar discs.
Correct Slouch:- Correct slouch Balanced rocking pelvic tilt and adjustable floating chairs allow the user to release the whole seat and back into free float thereby allowing the user to lean back and 'slouch correctly' whilst the chair supports the user. You must ensure that you remain in the correct position with bottom back and the chair back following the lumbar spine.
Incorrect Slouch:- Incorrect slouch Do not be tempted to slide forwards as this will stop the natural inward curve of the lumbar spine. Take care with synchro mechanisms whereby the "free-float" feature allows the chair back to go past 90° resulting in the pelvis rotating backwards to reduce the curve of the lumbar spine.
