This stuff is expensive. Most of anti-static carpet fabric will have wire threaded through it and a drain wire attached that you should ground.
Just to formally close out the carpet thread, there appears to be a single source for the stuff. 3M makes tiles and treatments, and many carpet companies have carpet that has a special anti-static backing, but only one seems to have "certified" static-free carpet. You can find it at http://www.utp.com. The process involves some type of conductive carbon fiber woven into it that is bound to a conductive backing. At approx. every 1000 sq. feet there is a grounding strap. The carpet is available in rolls or in tile-sized pieces, and looks to be completely safe for any computing environment. Pricing starts at about $22/sq yd. for the roll product. Any carpet installer should be able to order it and install it, as there is no special process involved other than attaching the grounding strap, and anyone who's handy should be able to figure that part out. The folks at UTP are pretty friendly on the phone and will answer any technical questions you can think of. You get some nice free samples if you call. We're going with this solution. Our machine room is very small, and the surrounding build/test/repair/work area isn't that much larger and could use some static reduction. Charles
It may be far easier to pick up a grounded chair mat that you can place at the table. Any used office supply place should have them.
