This was not the first time I purchased carpet for my office so I knew that I needed a high wear carpet and a very thin pad for the wheels of my equipment to work. I specifically told the salesman of this and was assured that would be possible.
That was a lie since the company does not carry more than one type of pad. When I complained about this the company offered to replace pad only if I purchased an entire roll of that padding and paid for reinstallation.
I have also found that their pricing was way out of line and one would be a fool not to negotiate price. I would discourage anyone from purchasing from such a company.
