Office Chair Always Rebounds

If an office chair always rebounds, there may be issues with the gas lift, seat cushion board, or the seal ring of the gas rod. Here are the specific causes and solutions:

Damage to the gas lift is a relatively common and dangerous cause. As the core component for the height adjustment function of an office chair, the internal sealing structure of the gas lift is crucial. If the sealing is poor, the internal gas will leak, preventing the chair from remaining stably at the set height and causing it to rebound. More seriously, a damaged gas lift poses an explosion risk. If an explosion occurs, it may cause serious harm to the user. Therefore, when it is determined that the rebound is caused by a gas lift problem, you must immediately stop using the office chair and replace it with a new gas lift. During the replacement process, choose products with reliable quality that meet safety standards to ensure safe use.

Deformation of the board inside the chair's seat cushion can also trigger a rebound problem. This situation generally occurs in particularly cheap computer chairs. Due to cost constraints, such chairs may use low-quality boards during production. After long-term use or uneven force application, the board is prone to deformation. A deformed board cannot provide stable support for the chair, leading to rebound. For this situation, you can find an experienced craftsman to deal with the deformed board, such as reinforcing it or adjusting its shape. After treatment, the chair usually will not rebound again.

Issues related to the gas rod for adjusting air pressure should not be ignored either, among which damage to the seal ring inside the gas rod is a common factor. The function of the seal ring is to prevent gas leakage inside the gas rod and ensure the stability of the chair's height. When the seal ring is damaged, the gas inside the gas rod will slowly leak out, making it impossible to maintain the chair's height and causing a rebound situation. In this case, you need to replace the seal ring inside the gas rod. When replacing, ensure that the specification of the seal ring matches the gas rod and that it is installed correctly to ensure the sealing effect.
