BMW Active Seat

The Active Seat is an advanced devel-
opment in BMW seats. These seats are
engineered with orthopedic consider-
ations so that you will be less fatigued
during longer trips and sitting for long
periods without moving. The seat is no
longer a passive link between the road,
the running gear, and the driver. In-
stead, by means of an active modifica-
tion to the seat's surface, the seat
causes weight transfers which are slight
and imperceptible. The basic seating
position is not changed by this.
In the seat's upholstery, beneath the
surface of the seat, there is a cushion of
fluid on the left and right. The fluid is
slowly circulated back and forth be-
tween the cushions by means of a
pump.
