What are the best ways to clean and maintain dining room chair foam to ensure its longevity and comfort?

To clean and maintain dining room chair foam for longevity and comfort, regularly vacuum the foam to remove dust and debris. Spot clean any spills immediately with a mild detergent and water solution. Avoid using harsh chemicals or excessive moisture, as they can damage the foam. Rotate and flip the cushions periodically to distribute wear evenly. Consider using a protective cover or upholstery cleaner to further protect the foam.
