My preschoolers love them! My class is 5 or 6, plus a few other flexible seating options. They are definitely favourites. You fall over when you stand up (I've seen people complain about this), but if you teach your students to put the pencil case on the floor next to them, then it's no problem if the seat falls over. I might get more in the future!
