While the chairs have been useful for me, they all have had problems with the screws loosening from the bottom making the chairs wobbly and dangerous. I’ve tightened them many times over and over but they eventually just go back to being lose again so it’s rather annoying. Another silly thing that happened is that the chair seat cushion on one of them just popped right off. It’s as if they were just glued on cheaply and meant to not stay together.
