For sale: Galvanized iron flying chair bases, same as the pictures. One is 80x40. The second is a bit shorter, approximately 70x40. I custom-made 4 bases, used two, and changed my mind about the remaining two. If you are in Al-Ahsa and want to see how they are installed, you are welcome. I had them made for 200 each and am selling them for the same price. Serious buyers, please contact me.
