Exploring Rub Counts and Durabi – Couch Potatoes Furniture


Selecting furniture for your home is an investment that should stand the test of time. While comfort and style are vital considerations, there’s another essential factor that often goes unnoticed but plays a crucial role in determining the lifespan of your furniture – rub counts.

In this comprehensive guide, we will explore why rub counts are necessary, what they entail, the two primary testing methods – the Martindale Test and the Wyzenbeek Test, and why Couch Potatoes relies on independent labs to conduct these tests.

The Significance of Rub Counts

Why Are Rub Counts Necessary?

Picture this: you’ve furnished your living room with a beautiful sofa, and within a short time, you notice it starting to wear out, with the fabric showing signs of damage. This is where rub counts come into play. Rub counts are a standardized measure of how well a fabric or leather can endure the wear and tear resulting from everyday use. They provide valuable information about a material’s durability, helping you make informed choices and ensuring your furniture retains its appearance and functionality over the years.

Understanding Rub Counts and Double Rubs

Rub counts, also known as abrasion resistance or double rubs, quantify the number of times a fabric can endure rubbing back and forth before revealing signs of wear. A double rub represents one complete back-and-forth motion. Fabrics are categorized into different levels of durability based on their rub counts:

  • Light Duty: Up to 9,000 double rubs
  • Medium Duty: 9,000 to 15,000 double rubs
  • Heavy Duty: 15,000 to 30,000 double rubs
  • Extra Heavy Duty: 30,000 double rubs and above

The Martindale Test

The Martindale Test is one of the primary methods for measuring fabric durability through rub counts. Named after its inventor, Dr. Roger Martindale, this test simulates the abrasion that fabrics experience during everyday use. The testing apparatus involves a circular specimen holder with a piece of testing fabric attached to it. The fabric is subjected to abrasion by rubbing against a standard fabric or worsted wool.

How Is the Testing Carried Out?

  1. Test Material Preparation: A sample of the fabric or leather to be tested is secured to the Martindale machine.

  2. Rubbing Motion: The machine initiates a circular rubbing motion, causing the test material to come into contact with the abrasive fabric.

  3. Observation: Trained technicians monitor the fabric for signs of wear, such as color changes, thinning, or fraying. The test continues until a predetermined level of damage is reached.

  4. Martindale Rub Count: The number of rubs completed before visible damage occurs is the fabric’s Martindale rub count.

The Wyzenbeek Test

The Wyzenbeek Test is the second primary method for measuring fabric durability through rub counts. Named after its inventor, Harold Wyzenbeek, this test assesses a fabric’s resistance to abrasion. In this test, a mechanical arm fitted with a testing material rubs against the fabric in question, replicating the wear and tear experienced during everyday use.

How Is the Testing Carried Out?

  1. Test Material Attachment: A sample of the fabric or leather is secured to the Wyzenbeek machine.

  2. Rubbing Motion: The machine initiates a back-and-forth rubbing motion using a specified force and speed. The test material rubs against the sample repeatedly.

  3. Observation: Trained technicians monitor the fabric for signs of wear, including color changes, thinning, or fraying. The test continues until a predetermined level of damage is reached.

  4. Wyzenbeek Rub Count: The number of rubs completed before visible damage occurs is the fabric’s Wyzenbeek rub count.

Scoring Rub Counts

Both the Martindale and Wyzenbeek tests yield rub counts, which indicate the fabric’s level of durability. The rub counts provide valuable information to consumers about a material’s resistance to wear and tear, enabling them to make informed decisions when selecting furniture upholstery.
