What does double rub rating mean for guest chair upholstery?

Double rub rating measures fabric abrasion resistance — one double rub simulates one cycle of a person sitting down and rising from the chair. A rating of 50,000 double rubs is considered adequate for light residential use; 100,000+ double rubs is the commercial standard; 250,000+ double rubs is heavy-duty commercial. For guest chairs in busy waiting rooms, specify 100,000+ double rub fabric to ensure durability over years of use.
