I purchased a Herman Miller chair from Madison seating a few years ago. Within 2 years the armrest material (? Leather) began to crack and look awful. Madison seating sent me a complimentary replacement pair which I installed myself. 3 years later, new armrests are cracking again! When I called today I was told they won't replace these and that I should go to eBay to get a replacement set. Even though the manufacturer (Herman Miller) warranties the arm rests for 12 years, the reseller (Madison seating) refuses to do so. For me it's all about customer service and this represents poor service.
