I had recently purchased an identical version of this chair from a local, brick-and-mortar vendor, and liked it enough to want a second. The second chair was delivered promptly, but it broke during the first two minutes of use. First, one set of rivets came undone. After trying to hold the chair together with tape, the second set of rivets quickly came undone as well. I am not particularly heavy (160 pounds), and I used the chair the same way I have been using the first one I purchased, so I don't think I did anything unusual or abusive. There is nothing in the product description that says that the chair is meant for infants!
I contacted the seller, and a representative promptly sent me a UPS label for returning the chair. Presumably, my credit card account will be credited with the purchase price. Of course, I still had to go through the time and expensive of preparing the chair for shipping.
All in all, I purchased the chair because it is very lightweight, but it also needs to stand up to reasonable use. I hope my experience was out of the norm.
