I use a wooden stool in my studio and yes my butt goes to sleep on it too! :lol: :lol:
I wish I could use something other than a stool but I need to be at a certain height for my bench and treadle. If I am in my house using one of my treadles in here I have a vintage sewing chair made just for treadles. It has lots of padding and a low back to it.
