Heated seats have been available in cars since the 1960s, but remain an optional creature comfort for most models. There are geographical regions where temperatures just don't require heated seats.
What may change their status from optional to standard is the introduction of cooled or ventilated seats in cars. For now, heated and cooled seats are part of option packages. For example, in the Buick LaCrosse, they are part of a $1,300 option package with leather seats and other upgrades.
Heating and cooling functions are typically paired. Drivers in regions not requiring heated seats may well appreciate the cooling effects of ventilated seats when hotter temperatures prevail. Drivers who experience one or the other of these features may find it indispensable when searching for a new vehicle.
