It was scientifically proven that the squiggly lines make the seat seem cleaner than it actually is.*
*Or not.
That’s why hotel carpets have similar godawful patterns. You can’t spot the stains.
Hey now, be careful about what heresy you speak; the Dragon-Con Cult of the Marriott Carpet doesn’t fuck around!
Wasn’t this just to make grafittis on the seats invisible enough to determine potential teenage artists?
“We need a design that obscures ketchup, vomit, and shit stains”
“Absolutely on it, sir”
Is there an actual reason behind it?
I heared it is that way so you dont see the dirt on the chairs
I also heard a claim that such patterns can (marginally) discourage graffiti of the seats. And if branding is a thing you care about, they can reflect some parts of that. London S-Stock trains’ seats point to the lines where they run, and there have been Danish trains that straight up feature the old DSB logo in the seat pattern.
