What does double-rub rating mean for lounge seating fabric?

The double-rub rating measures fabric abrasion resistance using the Martindale or Wyzenbeek test — each 'double rub' simulates one back-and-forth motion of normal seating use. Residential fabric: 15,000–25,000 double rubs. Light commercial: 30,000–50,000. Heavy commercial: 100,000+. For office lounge seating, specify a minimum of 50,000 double rubs; for high-traffic waiting rooms, choose 100,000+.
