What do fabric grades mean on an office chair and which grade do I need?

Upholstery grade specification at OfficeFurniture2go.com is application-driven. Standard commercial offices: Grade A (30,000–50,000 double-rub, stain-resist treated). Healthcare or food service: specify treated vinyl or performance Grade A+ fabric with explicit antimicrobial rating and bleach-dilution cleaning compatibility. Executive offices: premium fabric or leather grades for aesthetics. We specify upholstery grade with double-rub rating on every commercial chair order — not just grade designation, but actual abrasion testing data. Call 1-800-460-0858.
