if purchasing on their own, it's not the biggest deal - however we purchased these and the matching arm-chair versions of these and they don't match up a all. Nothing in the description or photos is different so I'm not sure if one was an older version and one was a new but now unfortunately we are stuck with 4 side chairs that have a dark charcoal metal color (NOT BLACK) and then two end chairs that do have the true black metal framing as they should have all come... They also oddly are 2 different seat heights. Very strange
