The Martindale test measures upholstery abrasion resistance; which values are enough for home and commercial use.
When a sofa fabric's catalogue says '40,000 Martindale', the figure tells you how well it resists abrasion. To interpret it correctly, though, you need to know how the test works and which range is enough for your use.
How is the test done?
A fabric sample is rubbed against a standard wool abradant in a figure-eight motion. Each full motion is one cycle. The number of cycles at which the fabric shows two broken threads or visible thinning is reported as its Martindale value (EN ISO 12947).
Which value is enough?
- 10,000 – 15,000: decorative use (cushions, a rarely used armchair)
- 15,000 – 25,000: light domestic use (guest room)
- 25,000 – 40,000: everyday family use (living-room sofa)
- 40,000 and above: heavy domestic use, homes with children or pets
- 50,000+: commercial use such as offices and hotel lobbies
Martindale is not the only criterion
Besides abrasion resistance, pilling, colour fastness (to light and rubbing) and stain resistance matter too. Linen blends breathe well but can wrinkle; velvet looks beautiful but its directional pile can show crush marks. Microfibre resists stains and releases pet hair easily.
Which fabrics does Mervo use?
Fabrics of 40,000 Martindale and above are standard on our living-room sofas; the Liman linen blend is rated 45,000 and the Zümrüt velvet 50,000 cycles. Because covers are removable you can wash them at 30°C. You can ask for free samples to see the fabric in daylight, and a fabric-selection appointment takes just 30 minutes.
Questions to ask when buying
- Was the fabric's Martindale report prepared to EN ISO 12947-2?
- What are the colour fastness grades to light and rubbing (on the 1–8 and 1–5 scales)?
- Is the fabric used as a washable cover or as fixed upholstery?
- Is there a fire-resistance (EN 1021-1/2) certificate?
A fabric may look good in a catalogue, yet in real life pet claws, denim dye and sunlight come into play. In homes with pets choose tightly woven microfibre or linen blends, and in sunny living rooms choose solution-dyed yarns resistant to fading.
Real life in a home
In theory 40,000 cycles cover about eight to ten years of regular use on a sofa sat on four hours a day. In practice lifespan varies with the way you sit, clothing friction, pets and cleaning habits. So when buying, look beyond the figure to the weave of the fabric and the option of a replaceable cover.
