They are not as flimsy as some of the other reviews made them seem.  They are not bulky at all which is perfect for what I needed them for.  I have them for my pub height dining table that seats eight and I can fit two on each side of the square table if I wanted to.  The other day I stood on one to reach something in a top cabinet and I was extremely sturdy.  Very happy, I may get more to finish out the table.
