First of all upon delivery there were no instructions stating you had to remove a bolt to take the plastic covering off the bottom plate.  One of them had some issues, which was resolved quickly.  With in a few months one of the plungers had fallen, so it looks horrible.  Now almost a year later the stain on some of them are wearing off. These stools are heavy making them impossible for me to lift and move.  Sliding them has caused some scratches in my wood floors.
