Office Chair Support Protrusion

Office chair support protrusions may be caused by unreasonable design, component aging, or damage, and protrusions in different positions can lead to different issues.

Support Protrusion Due to Unreasonable Ergonomic Design

Some ergonomic chairs have design flaws. The most protruding point of the backrest should be the sacral position, not the lumbar line position. The sacral position is a relatively stable part of the human spine and can better disperse pressure. If the protrusion position of the backrest is incorrect, the lumbar region cannot receive proper support. The lumbar spine requires an upward-supporting and slightly reclined slope, not a forward-protruding lumbar support. An unreasonable support protrusion design will keep the lumbar muscles in a tense state for a long time, preventing them from relaxing effectively. This can lead to lumbar discomfort, such as soreness and stiffness, and long-term use may even trigger lumbar diseases.

Protrusion Due to Deformation of Internal Springs in Old Office Chairs

For old office chairs, the internal springs may deform after long-term use, resulting in protrusions. When a person sits down, this single-point hard pressure on the perineal area can cause chronic irritation to the bladder. After being continuously stimulated, the bladder will frequently send out urination signals, causing the user to experience frequent urination. This not only affects the user's normal work and life but may also cause certain damage to the health of the urinary system.

Abnormal Protrusion of the Gas Lift

The cylindrical structure protruding from the bottom of a computer chair is usually the gas lift, which is the core component for realizing the chair's height adjustment function. Under normal circumstances, the gas lift does not pose a safety hazard. However, if the gas rod protrudes abnormally, it is likely that the five-star base is damaged, causing the gas rod to sink. The five-star base is an important part that supports the stability of the chair. When it is damaged, the stability of the chair will be severely compromised. At this time, the chair is at risk of tipping over or failing to adjust its height. Users may be injured due to the sudden tipping of the chair during use or encounter malfunctions when adjusting the chair height, affecting the user experience and safety.
