The Martindale test is a standard method used to measure the wear resistance of upholstery fabric. In the test, a machine rubs against the fabric a specific number of times to simulate normal use over time. The higher the number of Martindale cycles a fabric can withstand, the more durable it is. This is an important indicator when choosing fabric for furniture that will be used frequently, such as a sofa or an armchair. 10,000 to 15,000 Martindale: Suitable for light use and decorative purposes. 15,000 to 25,000 Martindale: Good for regular use in private homes. 25,000 to 30,000 Martindale: Very durable, suitable for frequent use in most homes. Over 30,000 Martindale: Extremely durable, suitable for frequently used public spaces.
