We had purchased the Siena mesh chairs a couple of years ago and, athough it states that the chairs can be left out all year, we did store them in the winter. On getting them out recently we noticed all the coating was cracked and peeling off. I contacted Dawsons World who we had purchased them from as there is a 3 year warranty on the product and they contacted Kettler on our behalf. We received an email directly from Kettler within a few days to confirm that all the chairs would be replaced. We felt this was excellent service and cannot fault our experience. Hopefully the new chairs will not have the same problem. Thank you Kettler for an excellent service.
