As with the previous comments, 5 of our garden chairs were showing signs of rust after 4 years but within the guarantee. I contacted Kettler by phone and sent photos via email for evidence. 5 replacement chairs were sent without any hassle. Everyone I spoke to was very helpful. My only minor complaint was that I was asked to re-send information on a couple of occasions. We also had a problem with the parasol which had come with the set but unfortunately they are only guaranteed for 12 months. We eventually managed to get it to work with brute force but it can only be used when in the central hole of the table now.
