This chair, according to the press release, is a "fusion of sound and feeling." I think I experienced that in college once, but it was chemically induced.
The BodySound vibrates in time with on-screen action and even has a volume adjust feature to improve hard-to-hear sections of dialogue. No MSRP, yet, but rest assured it won't be a $99.99 item. It will be unveiled at Home Entertainment 2005 show.
