An adjustable seat for a snowmobile has a base having an upper sitting
portion for accommodating a driver and a slidable coupling for sliding
the seat relative to a chassis of the snowmobile. The seat is movable
between a forward position and a rearward position. Threaded fasteners or
other connectors are employed to secure the adjustable seat to the
chassis in an ergonomic position. The adjustable seat thus accommodates
drivers of different height and/or drivers who adopt different postures
when riding by comfortably seating the driver on the sweet spot of the
seat regardless of the driver's height or his driving posture.
