Let me start off by saying that I have used this chair at least 10 times for clients and they always love them.  They are not the best quality but they are a great bang for the buck with regards to style, form and function.  We recently did these in the white vinyl for a client and the vinyl discolored very quickly.  Luckily they are sending a replacement chair but I am worried how they will wear in the future.  I personally own the dark grey fabric ones and have had them for 3 years and they are wearing quite well.
