It looked different, I'll sort of give you that, but advanced? What was advanced about it?
The glowing lights under the chairs?
From the first time I saw the movie in '84, I assumed the glowing supports were force fields and the chairs were suspended in air. Seemed pretty advanced to me at the time, and it still does today.
In fact, this look was duplicated on the Enterprise-D, because you never see supports for the three command seats (yes, they're really attached to the back wall, but I don't think that was the intention).
Arm rests that act as safety buckled for transwarp? I won't even get into how stupid that was. Even K.I.T.T. had an invisible laser restraint system for Michael. These people get manual arm rests.
Just because you can't see it, doesn't mean there isn't some underlying advanced technology at work. Perhaps engaging the arm supports creates a restraint field / individual inertial dampener that secures one's entire body in the chair.
