You shouldn't need any vibrations with this chair. Blood flow during sitting, is maximized with proper weight distribution, and good muscle tone. http://www.tradersworld.com/cgi-bin...v+Screen=CTGY&Store_Code=TW&Category_Code=TRC Jeffrey
robert- i've been looking over some other software...and it seems to me it would be nice to have some type of programable alert system like some of the other packages offer for ex: being able to set an alert that would show stocks in the s& p that had a five min bar w/ a low but higher close than the previous bar... or maybe something that would alert you to a nas 100 stock that is breaking through a bollinger band intra-day i know some co's have this, but I've heard mnay of them don't work well I 'd be interested in hearing what your own wish list is on software, and how things are progressing with this. Peace
