I have two (2) Aeron chairs by Herman Miller. Both needed servicing. After weeks of attempting to get Herman Miller corps to help me, I tried a different approach. I called the local Herman Miller franchise dealer. I spoke with one of the most professional folks I have dealt with in a while, Ms. Carol Grimes. With her help, I was able to get both chairs fixed in less than a week. My chairs were NOT under warranty, but I felt the fix, service and quality was worth every penny I paid. My wife needs a new office chair. I will ONLY go to Carol and her staff for that purchase. I highly recommend them. Bravo Business Interiors. read more
