upholstery grade:
Is a designation of a fabric as suitably durable for use in upholstery.
Upholstery grade fabric is typically more durable than fabrics used for general purposes (including fabric used for drapery and other window fashions).

Fabric durability (in part) is measured in “double rubs” and this measurement is usually indicated along with other details of the fabric’s composition at a fabric store.
The fabric on a typical upholstery piece might be rated between 25,000 and 50,000 double rubs. A piece of hotel furniture on the other hand might use a higher grade around 100,000 double rubs because of the extra wear.
