I bought 4 of these and they are holding up very well.  2 at first, then ordered another 2 weeks later because we liked them.  It's been over 90 days with daily use in a family with kids and parents/grandparents who are overweight. (just the parents, over 225 :-D )
My only gripe about the chairs would be they didn't come with rubber washers that go between the metal bases and actual chair.  I'm sure wayfair would have sent some but I went to the hardware store and bought new ones.  All 4 metal bases lined up with the chair base holes and took just a few minutes to put together.  They came with a allen wrench for assembly, my suggestion (because of the clear plastic, it has a molded metal nut inside) would be to *not* over tighten the base screws, keep the wrench nearby to retighten if they come loose.  After 90 days of use, for me, all 4 chairs needed retightening...not a big deal.  Hope this helps others.
