The company I work for manufactures them and has done so since the 1980s. The ones we typically make have a polished stainless steel cylinder base that adjusts in height from 17" to 28" from an internal lift mechanism operated by remote control. We just sent one to Russia, and I am concerned that the remote control might be operating at a frequency that may violate their radio wave regulations! They are only supposed to be used in the U.S. Our furniture is at the extreme of high end, and so it is excellent quality, but with a price to match. The table is not in our catalog but can still be custom ordered.
