Using this green office chair is easy. Just sit on it and enjoy your work or relaxation time. Since it's non - adjustable, it offers a fixed and stable sitting position. When using, avoid putting excessive weight on one side to prevent imbalance. As for maintenance, regularly wipe the chair with a soft, dry cloth to keep it clean. If there are stains, use a mild cleaner. Remember, this chair is a used item, so it might have some normal wear marks. And don't forget it's only for local pickup at the MSU Surplus Store.
