Time was if you wanted to keep your kids in the jump seat of your extended cab pickup, you had to make a cage out of chainlink fencing.
But with the revolutionary Jump Seat Extension Headrest, the 2015 GMC Canyon has finally led us out of those dark, Social Services-alerting days. The Canyon's rear headrests are designed to pup into the front edge of the jump seat, thereby giving you the requisite seat bench area to safely install a child's car seat.
This short seat depth problem is endemic in Japan as well, but there, rather than cages or headrests, all the car seats come with floor braces. I think the Seat Extension Headrest solution is far more elegant.
