Office Chair Headrest Too High

If the headrest of an office chair is too high, it can be resolved by adjusting the sitting posture and the height of the headrest; if it is non-adjustable, short users are advised to replace it with an ergonomic chair that fits them.

Health Risks of an Overly High Headrest

An overly high headrest forces the head to tilt forward, causing excessive cervical spine flexion. Long-term use may lead to cervical muscle strain, straightening or even “reverse curvature” of the cervical spine's natural curve, increasing the risk of cervical spondylosis. The correct support position for the headrest should be the lower part of the cervical spine (the base of the neck near the shoulders), not the back of the head. When sitting upright, the distance between the back of the head and the headrest should be controlled at about two finger widths (no more than 4 cm), and the center point of the headrest should be level with or slightly higher than the top edge of the ears.

Adjustment Methods for Adjustable Headrests

1. Adjust Basic Sitting Posture:

   • Keep your hips pressed against the backrest, feet flat on the ground, and thighs parallel to the ground.
   • Adjust the backrest angle to upright or slightly reclined at 100°–110° to maintain the natural curve of the spine.

2. Operate Headrest Height:

   • Press and hold the unlock button below the side support rod of the headrest, then lift or press down the headrest to the desired height.
     • Lifting Up: Simply lift the headrest to the appropriate position.
     • Pressing Down: Press and hold the unlock button before pressing down to prevent the headrest from rebounding.

3. Verify Adjustment Effect:

   • Check if the center point of the headrest is level with the top edge of the ears and if the gap between the back of the head and the headrest is about two finger widths.
   • Ensure the headrest is locked securely to prevent sliding or dropping during use.

Solutions for Non-Adjustable Headrests

If the headrest of the chair cannot be adjusted, short users (e.g., under 160 cm) may find it unusable because even the lowest position of the headrest is still higher than the cervical support point. In this case, it is recommended to replace it with an ergonomic chair designed specifically for short users, such as the ErgoMaster i5. These chairs are optimized in the following dimensions:

• Headrest Height: Fits the cervical position of short users, avoiding being too high or too low.
• Size Fit: Reduces the size of the headrest, lumbar support, and seat cushion to match smaller users.
• Support Position: Precisely supports the base of the neck, lumbar spine, and hips, reducing issues of being “out of reach” or “hanging in the air”.

By making scientific adjustments or replacing with a suitable chair, the issue of an overly high headrest can be effectively resolved, reducing the risk of cervical spine injury and improving sitting comfort for extended periods.
