What is a double rub?
It sounds like a strange term to find on a fabric, but double rub counts is actually the industry standard for measuring fabric durability.
Whether you are furnishing a busy family room or outfitting a high-traffic office, understanding these numbers is the secret to buying furniture that will last! Here is a breakdown of what double rub counts actually mean, how the testing works and what it actually says about the life expectancy of your fabric.
What Exactly is a “Double Rub”?
A double rub is a measurement of abrasion resistance of a fabric. Simply put, it tests how well a fabric can handle the friction of daily use before it starts to show visible wear, tear or yarn breakage.
Think of a “double rub” as a simulation of someone sitting down on a piece of furniture and getting back up again. The forward movement is one rub and the backward movement is the second rub—hence the term, “a double rub”.
To determine this number, the textile industry relies on two primary testing methods. While they both measure abrasion, they do it in completely different ways.
The Two Methods: Wyzenbeek vs. Martindale
In our showroom, you will see both of these testing methods used by our suppliers. Because Canadian manufacturers import textiles from across the globe, understanding the difference between the North American standard and the international standard is highly beneficial.
1. The Wyzenbeek Method (The North American Standard)
The Wyzenbeek test is the standard used across North America. Most of our manufacturers use this method. A piece of rough material (usually heavy cotton duck canvas or a wire screen) is rubbed back and forth over the test fabric in a straight line, going along both the warp and weft (the vertical and horizontal threads).
The machine counts every full back-and-forth motion as one “double rub”. The test stops when the fabric shows noticeable wear. This is officially defined as “two yarn breaks”.
2. The Martindale Method (The International Standard)
If you are looking at European fabrics or globally sourced furniture, you will likely see a Martindale rating instead.
Instead of a straight back-and-forth motion, the Martindale machine rubs the fabric in a continuous, oscillating figure-8 pattern. This is designed to simulate natural, multi-directional wear and tear. The results are measured in “cycles” or simply “rubs” rather than double rubs.
How They Compare
| Feature | Wyzenbeek | Martindale |
| Primary Region | Canada (& USA) | Europe & International |
| Motion | Straight back-and-forth | Figure-8 / Oscillating |
| Measurement Unit | Double Rubs | Cycles / Rubs |
| Best For | Heavy-duty, structured use | Multi-directional wear |
Note: Because the motions are so different, there is no direct mathematical conversion between Wyzenbeek and Martindale scores. A fabric that scores brilliantly on one test might only score adequately on the other.
Translating the Double Rub Count Numbers: What Do You Actually Need?
Now that you know how the numbers are generated, how many do you actually need? The Association for Contract Textiles (ACT), whose guidelines are widely followed in Canada, sets clear benchmarks for double rub counts.
Residential Use (Wyzenbeek)
- Delicate/Decorative (Under 3,000): Best for throw pillows or formal dining chairs that are rarely used.Light Duty (3,000 – 9,000): Suitable for formal living rooms.Medium Duty (9,000 – 15,000): Great for standard family rooms.Heavy Duty (15,000+): Ideal for busy homes with children, pets, and daily Netflix marathons.
Commercial & Office Use (Wyzenbeek)
- General Contract (15,000 – 30,000): The bare minimum for a standard office, private workspace, or waiting room.Heavy Duty (30,000+): Required for high-traffic environments like hotel lobbies, restaurants, and 24/7 hospital waiting rooms.
(If you are looking at Martindale ratings, 20,000 cycles is great for general domestic use, while 40,000+ cycles is recommended for severe commercial use.)
Life Expectancy and the “Indestructible” Myth
It is a common industry rule of thumb that a 3,000 Wyzenbeek double rub count equals roughly one year of regular use. Therefore, a fabric rated at 15,000 double rubs has a theoretical lifespan of about 5 years under consistent, everyday use.
However, you shouldn’t fall into the trap of thinking that a higher number alone guarantees a fabric will outlive you.
Sometimes, manufacturers boast massive numbers like “250,000 Double Rubs” to make a fabric seem indestructible. But according to the ACT, abrasion test results that far exceed standard guidelines (like 30,000) do not often indicate a proportionally longer product lifespan.
Why? Because friction isn’t the only thing that can shorten the life of a sofa. A fabric with a 150,000 double rub count might be incredibly resistant to abrasion, but it can still succumb to:
- UV fading from sitting in a sunny window.
- Harsh cleaning chemicals (especially in medical or commercial settings).
- Staining or seam slippage.
Furthermore, ultra-high double rub fabrics often require incredibly tight weaves. This can make the fabric sometimes feel stiff, boardy and less comfortable to sit on.
The Bottom Line for Double Rub Counts:
When shopping for upholstery at Lfurniture, aim for the sweet spot. If you want a durable family couch, look for a Wyzenbeek rating of 30,000 to 40,000+ double rubs (or 15,000 to 20,000 Martindale cycles). This will give you excellent longevity without sacrificing the soft, comfortable feel you want in your home. You will however find most of our fabrics at around the 100,000 double rub count (wyzenbeek rating). But most importantly whichever fabric you choose, make it a fabric you actually like – Because at L Furniture whatever you buy is going to last a very long time!!
