I purchased these chairs in order to have a few extra seats for a poker night I was hosting. They arrived promptly and seemed to fit the bill in terms of quality and value for money, however as soon as one of the chairs was used it became apparent that the design simply doesn't work. The back support frame of the chairs is not connected to the chair's back/support tubes, it is simply meant to rest against it in order to provide the necessary support, which basically doesn't work at all. If you look at the picture of the item, the black bits which connect the back leg support to the main frame chair are simply little bits of cheap plastic that are moulded to fit the shape of the main frame, thereby supporting them. However the plastic bits are not actually secured to the top of the frame and therefore pop off when any pressure is applied to them, rendering the entire chair useless because without that support, the chair collapses. We had several people of varying sizes try to use this chair and it still malfunctioned under the weight of the smallest person in our party (whose weight I would guess to be around 9 stone).
