Back Pain Caused by an Office Chair That's Too High
Back pain caused by an office chair that's too high can be alleviated by precisely adjusting the chair height, properly adjusting the lumbar support, and adopting good back-care habits.
Precisely Adjust the Chair Height
If the chair is too high, the soles of the feet will be off the ground, the knees will be raised, the pelvis will tilt forward, the lower back will lack stable support, and the muscles will become tense over the long term, leading to soreness. When adjusting, use the naturalไธๅ of the elbows, with the elbow joints at a 90 - 110ยฐ angle and the desktop slightly lower than the elbow joints as a reference. Adjust the height by turning the lifting rod clockwise to raise it and counterclockwise to lower it until the soles of the feet are completely flat on the ground, the knees are bent at 90ยฐ, the thighs are parallel to the ground, and the feet can step firmly on the ground without tiptoeing or hanging in the air. You should be able to get up without using any external force, which indicates the appropriate height. If your height is insufficient and your feet are off the ground, you can use a footrest that is 10 - 15cm high to keep your feet flat. If the chair height cannot be adjusted, place a wooden board under the seat to raise your hips and use a footrest to level it out.
Adjust the Lumbar Support Properly
A good lumbar support can increase the coverage of lumbar support from 40% to 89%, preventing muscle fatigue. The core criteria for adjusting the lumbar support are to position it at the lumbar dimples (3 - 5cm above the belt, the position pressed by the thumbs when placing your hands on your hips) and adjust the pressure to just support the lower back without being too tight. It is best if the lumbar support can automatically push forward by 2cm when leaning forward to type and remain in close contact when leaning back. Different chairs have different adjustment methods: for chairs with adjustable lumbar support, first raise the height to align with the lumbar dimples and then adjust the front-back tightness; for chairs with fixed lumbar support, use a 5cm thick supportive cushion; for chairs without lumbar support, roll up a towel and fix it in the corresponding position with tape as a temporary lumbar support.
Adopt Good Back-Care Habits
Take regular breaks: Get up every 45 minutes of sitting, move around for 3 minutes, and do 15 twisting movements to activate the core muscles and relieve lower back pressure. Check the desktop height: After adjusting the chair height, the desktop should be level with the elbow joints to avoid bending your head or stretching your arms, reducing lower back compensation. Choose the right chair: If you have a limited budget, you can choose a basic model with a 4D lumbar support, which can provide good lower back support.
