In my part of the world (NZ) the word moquette is rarely used and it wouldn't surprise me if most people don't even know what it means. Our houses are carpeted, generally wall to wall, and we have mats on the floor, or rugs- these words are both used. But DL is still not accepting mat.
Rugs and mats are the same thing where I come from yet DL will not accept mat. I have reported this a number of times as I always get caught out trying to remember which of the two words DL will accept. Mat is a broader word than rug, but rugs are mats...at least in my part of the world.
