That would take another poll. 
I wasn’t thinking of any specific type of bath mat. We use just put hand towels on the floor, and they are only used as bath mats. I would like to have the typical hotel bath mat - the one which is similar to a hand towel, but slightly heavier.
The ones here typically have a backing, which will break down fairly quickly due to floor heating, or are really thick and heavy, so they don’t dry very fast.
Because we use a hand towel, it is pretty damp after my husband (who steps onto it and then dries off) uses it. But it dries fairly quickly due to the floor heating. Just not fast enough, if I happen to take a shower after him. So I shower first.
When we’re at my parents, who have a big fluffy bath mat, we hang it over the edge of the bathtub, or over the bar on the sliding door to the tub.
Regarding the washing of towels, the towels, that means the hand towels in the bathrooms, plus the bath towels, get washed approximately once a week. But we use fresh washcloths (husband actually uses a bath mitt, like these) every day, and change the dish cloths every 3-4 days, depending on how much we’re cooking at home.
Cite? I couldn’t even buy cheddar here (Switzerland) the first 5-6 years, and it’s only been the last 2-3 years that there’s any cheddar made here.
This website says Mozzarella is the most popular. As it’s popular in both Europe and the U.S., especially on pizza, that seems reasonable.
Of course, for straight eating, cheddar is better. Mozzarella is only worth eating straight as string cheese.
