Office Chair Spring Too Tight

The tight spring of an office chair can be resolved through the following methods:

1. Manually Adjust the Recline Spring Tension
Some office chairs allow manual adjustment of the recline spring tension, usually with an adjustment knob located on the chair's base. Turning it clockwise tightens the spring, while turning it counterclockwise loosens the tension. For example, all models of Hengfa ergonomic office chairs are equipped with adjustable reclining bases, allowing users to operate directly without additional tools. Before adjusting, confirm whether the chair supports this function to avoid damage from misoperation.

2. Adjust the Spring Structure of Regular Office Chairs
For regular office chairs without an adjustment knob, try the following steps:

• Locate the Fixed Components: Flip the chair over and find the fixed screws or clips under the seat (usually located at the bottom edge or side).
• Loosen the Fixed Components: Use appropriate tools (such as a screwdriver or wrench) to carefully loosen the screws or clips, avoiding excessive force that could cause components to fall off.
• Adjust the Spring Shape or Position: Gently press on the chair's spring to feel its elasticity. If the spring is too tight, use your hands or small tools (such as pliers) to adjust the curvature of the spring appropriately, for example, straightening the curved part slightly or adjusting the spacing between springs to reduce tension.
• Re-fix the Components: After adjustment, ensure the spring is in a stable position, then re-tighten the screws or clips to prevent the chair from wobbling.

3. Add Cushioning Material to Relieve Pressure
If the tight spring makes the seat too hard, add cushioning material between the spring and the seat surface:

• Select the Material: Use thin foam pads, soft fabrics, or memory foam, cut to match the size of the seat's spring area.
• Installation Method: Lay the cushioning material flat on top of the spring, then cover it with the seat's fabric or leather, ensuring the material is smooth and wrinkle-free. This method effectively disperses pressure and improves comfort, but regularly check if the material has shifted.

4. Seek Professional Repair Services
If users are unfamiliar with the chair's structure or the issue persists after adjustment, it is recommended to contact a professional repair shop or after-sales service center. Technicians can precisely adjust the spring tension using professional tools (such as spring stretchers) or detect issues like spring deformation or breakage, ensuring the repaired chair's safety and durability.

Precautions: Cut off the power before operation (for electrically adjustable chairs) to avoid pinching injuries; wear gloves when adjusting the spring to prevent scratches; if the chair is under warranty, contact after-sales service first to avoid affecting warranty terms.
