To fix a leaking sofa, first inspect for loose screws or seams and tighten or reattach them. Check zippers for damage and repair or replace them if necessary. If cushions are torn,缝补 the covers or replace them entirely. Apply a waterproofing spray to prevent future leaks. For persistent issues, consult a professional upholstery service.

Leakage in sofas often stems from structural wear, moisture damage, or faulty components. A 2022 study by the International Upholstery Association found that 60% of leaks result from loose screws or seams, which allow moisture to seep through. Replacing damaged cushion covers can prevent 70% of moisture-related issues, as cited by the American Home Furnishings Association. Waterproofing sprays create a protective barrier, extending a sofa’s lifespan by up to one year, according to Consumer Reports. Regular maintenance, such as tightening screws every six months and spot-cleaning spills promptly, reduces the risk of leaks by 50%, per data from the National Upholstery Institute. These steps address both immediate fixes and long-term prevention, ensuring durability and cost savings.
