What is the seat height of the Eames Executive Chair -if on casters?

As a handicapped and very small adult, it is imperative for me to see all the measurements, especially seat min./max., and best to receive the information directly from you -not third parties.

Also, do you have more detailed descriptions of the chair fabric options -elsewhere here on your site or perhaps in a catalog?

As displayed now, subtle yet important factors remain elusive between your options: one fabric may be considered quite comfortable and hardy for the demands of a long-hours, large-staffed office while another fabric may be widely agreed as the softest against the skin and while also long-lasting, perhaps better suited to the demands of one person's daily usage.

Thank you for the ease of a Product Q & A option here -and of course for the incredible products you offer.
