We were extremely happy with these until the first rain.  These are supposed to be aluminum but when I moved them after the rain a huge puddle of rust water came out of the chair every time it was moved (picture is after I wiped up the first puddle) and there are large rust spots on the foot rest but that doesn't account for all the rust water - not sure where that is coming from but it appears to be from inside the chair itself!!  Very disappointing as we bought two sets.  Very misleading description.
