I have no idea how long these things will last before rust sets in but do not care, rust on furniture like this is part of the charm. The double chair was a bear to put together, you need two people and about two hours but the single chairs and the table are quick and easy. I recommend putting the double together first and definitely use your own tools. As a side note, I priced one of these chairs at a local supply, can tell it's exactly the same mfr, and they wanted 89.00 each plus 10.00 to out it together, so this is a good deal. I only received one box when I placed the order and was told on the phone that the other part of the order could not be fulfilled and I would not be getting the rest of the order, I could take a 20% discount or cancel ... there went my good deal! So I demanded the cancel and arranged for the one box to be picked up, and was given a refund. The next day the other box arrived, so I cancelled the refund etc. That was a little irritating but it all worked out in the end. I really like the grasshopper green color sitting out in the grass in my yard, looks good.
