First of all they did not deliver on time. Second, the chair was extremely poor quality, the adjustment mechanism broke down after three weeks use. I've tried to get this product replaced or repaired, or claim 30 days money guarantee Madison Seating offers. They replied there is no warranty, there is no money back, I cannot replace the chair because "I was supposed to file a claim immediately with the carrier when it arrived". When I unpacked the chair it seemed ok, but it did not last more than 3 weeks. They either sold me extremely poor quality product or the one with latent defect and they did not want to find a solution for the problem. They do not reply to my emails on time, they promise on the phone they would come back with some solution or at least the answer the next day. They never do. I had to send numerous reminders so they could finally reply that I am not entitled to get the money back, or replacing the item even when it doesn't work after 3 weeks of normal use. Very bad customer service, very bad quality product for approx $200 price."
