These are ex school solid beech stools, I have done nothing with them their charm is in their history. Maybe you sat on one in past times? I think they are art room stools, they have the handle hole at the top. Their simplicity would fit well with current interior décor trends and are a versatile size for many different rooms; kitchen, bathroom or they would work well as bedside tables.
