Perhaps the wrong place to ask...but anyone know anything about the grading or standards for cloth used for furnishings - specifically our 3 piece lounge suite. The cloth no is A202 Feathers Beige and is shown as 36% Cotton, 18% Spun Rayon and 46% Polyester. And I have seen other bits of cloth used for furniture covering advertised with references B, C, D etc...no doubt the letters refer to the quality and make up of the cloth...just wondered if anyone had knowledge of where to find info about the cloth grading. Thanks. John.
