Love the chairs.They seem to be well built. I love that the screws go into a metal lined hole, not just wood. They were hard work getting four screws to line up a one time, but doable if your patient. On a couple he had to do three screws and tighten them first. The fourth screw would then line up to go in. The fifth screw always went in easily. These screws hold the seat to the back, so we feel this is very sturdy now. Hope to have these chairs a very long time
