Our church bought 8 of these 2 years ago, then bought 8 more, mainly as a trial run before committing to buy another 320 for our Fellowship Hall. The 16 chairs worked well, no issues, so in 2020 we bought the 320 also. We did not purchase either of the extended warranties, cost prohibitive for that many chairs. Overall, they have done well, but we have had 6 or 8 collapse. The distributor replaced the first 3 with no problems. We haven't asked them to replace the more recent ones. We've learned about static weight and dynamic weight. The chairs are rated at 500 lbs static weight and 330 lbs dynamic weight. A 350 lb person should be able to carefully sit in the chair without issue, but if they plop down in it, it will likely collapse. We also discovered that it's far more likely to bend the frame and collapse if the seat isn't pushed totally flat. If it's just halfway opened...look out! I think these chairs would be fine for residential use, but beware if you use them in commercial settings.

Very happy with the chair.It has no problem supporting me weight.Comfortable to sit in.

Overall these chairs are adequate for my needs. Not quite as sturdy as I had expected, but a good value for the price paid. I would purchase again.

Looks good after just receiving them at the store. I will have to see how long they last.
