The spring stool keeps rotating, which has the consequences of explosion. Because frequent rotation can easily lead to explosion, the spring will be damaged after long-term use, or the internal air pressure changes will explode. When using the chair, try to avoid repeatedly rotating or lifting the chair, do not sit down violently, and do not often sit at the front edge of the chair to avoid the chair being damaged by torsional force. Once cracks and looseness are found, they should be repaired and replaced in time.
