Checklist Questions: Is the turf FIFA-certified or just “FIFA-approved quality”? What is the pile height (40mm–60mm is standard for football)? What type of yarn is used (monofilament vs. fibrillated)? How many microns of UV protection does it have? What is the expected lifespan (usually 6–8 years)? Do you provide installation + maintenance support? Is there a warranty (minimum 5 years recommended)?
