What is a double-rub rating and why should I care about it for lounge fabric?

The double-rub rating measures how many cycles of friction a fabric can take before showing wear — each double rub simulates one back-and-forth motion of someone sitting. Residential fabrics typically land at 15,000–25,000 rubs; light commercial starts around 30,000–50,000; heavy commercial goes 100,000 and up. For any office lounge chair, aim for at least 50,000 — and if it's a high-traffic waiting room, go 100,000+. FindOfficeFurniture.com lists double-rub ratings on every fabric option — call 888-719-4960 to make sure you're spec'ing for your actual traffic level.
