The carpet is very thin and limp, just around the corner in an apartment building but that does not matter. bottom is rubber and above a "flat plastic threads-gefussel" I do not know how to describe it better ... thus you can definitely cede dirt, but wet shoes remain just wet. Unfortunately, he stinks at the beginning also insane, but has ausgedünstet after a week approx. and he is a little too wide for an average inHaus doorstep, thereby fold the sides up. still looks great :) is more a decorative than useful object.
