Our fabric is of the highest quality. It is Double-rub abrasion tested ensuring durability. Hotels are tough on chairs and they request fabrics from 15,000 to 30,000 Double-Rubs; standard fabrics used on Bertolini church chairs are tested from 50,000 to 250,000 Double-rub without showing signs of wear. These fabrics were also tested for colorfastness when exposed to light. Bertolini uses only the highest quality commercial fabrics from leading mills in the United States. The mills we associate with have some of the strictest quality control procedures in use today. The high standards set by our mills translate into a church chair of the highest quality that will last for many years to come.
