Mattresses with horsehair
In order to keep the heat balance of our body we need air as well as water. Our body sweats all day in order to maintain this balance, the air circulation ensures the evaporation.
Our body needs the same process during the night, because while we sleep, our body sweats about a half to one liter of water. If we want to drain the sweat properly, the place where we sleep should have a very good air circulation. If you ventilate you bedroom, the horsehair "breathes" fresh air and "exhales" moisture that way your bed stays dry. Thanks to this circulation your mattress will always be clean and you'll feel as if you're lying on a cloud.
