Office Chair Pricking

Office chair pricking can be caused by different defects in pneumatic lift chairs, rattan chairs, and bow-shaped office chairs, requiring targeted handling and seat repair.

Common Causes of Office Chair Pricking

1. Pneumatic Lift Chairs:

   • Damaged seals on the pneumatic rod can lead to oil leakage, potentially exposing metal parts that may prick. Immediate discontinuation of use and contacting the manufacturer to replace the five-star base is necessary.
   • When the high-pressure nitrogen inside the pneumatic rod is abnormal, the rod may shoot out like a bullet, causing serious injuries. Such incidents have been reported, so caution is advised against low-quality products.

2. Rattan Chairs:

   • Material and Craftsmanship: Low-end PVC imitation rattan materials feel hard and can become brittle and crack under sun exposure, producing burrs. Natural rattan, if of poor quality or improperly processed, may have fibers with poor elasticity, becoming rough and hairy.
   • Environmental Factors: Natural rattan chairs should not be placed outdoors or in humid environments for extended periods, as alternating dry and wet conditions can accelerate brittleness.
   • Lack of Maintenance: Long-term neglect of cleaning can lead to dust wearing down the surface, and the lack of oil nourishment can cause the rattan to dry and crack, producing burrs.

3. Bow-Shaped Office Chairs:

   • Quality defects can cause the outer layer of the seat cushion to expose steel wires, with the ends of the wires easily piercing through the seat surface, posing a pricking hazard.
   • The market is flooded with "three-no" (no brand, no factory address, no production license) and low-quality products lacking production information and quality assurance, so caution is advised in selection.

Steps to Handle Pricking Injuries

1. Remove Foreign Objects:

   • Wood splinters: Use a sterilized needle or tweezers to pick them out, gently pulling along the direction of insertion.
   • Metal fragments: Use a magnet to attract or tweezers to pick them up, avoiding residue.
   • Plastic burrs: Trim with scissors or sand with sandpaper until smooth.

2. Disinfect the Wound:

   • Wipe the wound with an alcohol swab in a circular motion. If the skin damage exceeds 2 millimeters, apply erythromycin ointment to prevent infection.

3. Inspect and Repair the Seat:

   • Fabric Material: Use a crochet hook to flatten fiber burrs and avoid further friction.
   • Leather Seats: Apply leather care oil to soften and restore surface smoothness.
   • Solid Wood Furniture: Apply beeswax to fill gaps and prevent wood splinter regeneration.

4. Prevent Secondary Injuries:

   • After repair, regularly inspect the seat to avoid reusing damaged parts.

Special Repair for Rattan Chair Pricking

1. Cleaning: Use a soft-bristled brush to remove dust and avoid wearing down the surface.
2. Physical Sanding: Use sandpaper or a fine file to gently sand the burrs until the surface is smooth.
3. Apply Special Oil: Choose natural rattan maintenance oil to moisturize the fibers and enhance toughness.
4. Daily Maintenance: Avoid sun exposure and humid environments, regularly clean and apply oil to significantly extend the lifespan.
