Ultimately I am very pleased with the service I received from Madison Seating. The first Criterion chair they sent me was faulty (wouldn't maintain its seat height), and I was encouraged to return it via FedEx (paid by Madison). I was slow to make this happen (truth be told) and by the time I got around to it, I was unable to disassemble the chair as advised (simply would not work). After further consultation, the company agreed to send me a new chair without having to return the original broken one. I was extremely grateful. My new chair is working beautifully, and a fabulous chair it is: comfortable, sturdily built, attractive, and wildly affordable (given the discounted price). Thank you!
