And you need a grounded anti-static floor mat for the chair's grounding bead chain to connect to(by drag). Also anti-static shoes or heel/toe straps.(had to wear these at Tektronix,but didn't have anti-static chairs.Had the floor mats,too,along with anti-static smocks and wrist straps.)

Except there's no way to know the day-day conductivity of that method(it's too inconsistent)
Which have to use heel or toe straps or anti-static shoes. I'm not any expert on this,but IMO,a wrist strap is sufficient,if maintained,checked daily,and used properly.

I appreciate the need for state-of-the-art grounding techniques when it comes to electronic assembly, production areas, clean-rooms, etc.
I am looking for a solution for the typical office environment, where in the winter indoor humidities can be very low, and the majority of static buildup seems to be not necessarily from walking on carpet, but from getting into and out of chairs. (and the use of grounding mats, clips and straps are not desirable).
It seems that the rubbing of one textile against another causes a large static buildup that I was hoping could be alleviated by a different construction of the chair (exterior fabric and/or interior padding).
I can spray 1/2 a can of static-guard into the seat and back cushion of any given chair, but I don't think it lasts too long.
Is there no office furniture maker that has a line of static-reduced office chairs that feature some sort of conductive fabric or padding? Is there no demand for this sort of thing?
(I would post this to rec.office.equipment.chairs, but alas such a useful NG doesn't exist - not that rec and office don't go together...)

Well,the chair is only part of the problem. IMO,the best and simplest method would be to introduce more humidity into your office. 40-60% RH is the desired range. That might even be cheaper than buying anti-static office chairs! Even a portable humidifier would suffice.

7000 sq. feet. 14 ft ceilings, 8 or 9 ft suspended ceiling. Lease is up in 1.5 years. Have no intention of buying/installing hvac equipment into a premesis that I don't own.
Have drum-type humidifier at home (integrated into forced-air furnace). Set-point is 100% (ie it runs ALL the time in the winter). It barely keeps the house at 40% RH. Have never seen humidifiers spec'd for an office-type hvac setup (at least not for our size).
Yea, installing 1 or 2 of those residential-type drum humidifiers directly INSIDE the main air supply duct (2 ft x 2 ft cross section) would probably have done some good. But I'm not going to do that for just 1 more winter.
I've messed with those before. "messed" is the operative word here.
