Microfibre Grades: What the Numbers Mean
Microfibre fabric is rated by weight (gsm — grams per square metre) and rub count (double rubs — a measure of abrasion resistance). For a sofa seat that will be used daily, minimum 180 gsm and 250,000 double rubs is the specification to ask for. Anything below 150 gsm or 200,000 double rubs is a short-lifecycle product. Premium microfibre used in luxury applications is 200–250 gsm with 400,000+ double rubs. Ask for the technical datasheet before purchase — any reputable brand will provide it.
