Major design flaw! One of the 2 of these chairs I ordered in November 2023 has already broke. The seat is welded to the base and these welds are not strong and do not hold up to normal use. It looks like there are bolt holes ...looks like they should have bolted them together....maybe bolts would have been stronger? Meanwhile it is over the 30 days and now have one (and maybe soon a second) useless chair.
