With an exterior identical in every way to our quality stock seat our Heated Driver’s Seat comes with the added perk of integrated heating that’s designed to keep you warm and comfortable when temperatures start to dip. Stock equipment on the limited edition model.
With comfort seat, this:
COMFORT SEAT

$ 699.99
Extra padding in all the right places in addition to a memory foam layer gives us every reason to call it our Comfort Seat. Smartly styled, its elevated passenger seat gives anyone coming along for the ride a scenic way to enjoy the open road.
And for heated comfort, which is what I got, this:

All the features of the much-loved Comfort Seat with integrated heating. Unit complete with individual
dual-intensity driver and passenger controls for customized warmth when the weather’s cool but the ride is still hot.
So for $210 more you get individualized heat for driver and passenger. That seemed worth it to me. in addition to the
Extra padding in all the right places in addition to a memory foam layer gives us every reason to call it our Comfort Seat.
