Jaguar has designed a comfortable seat for the XK, adjustable in myriad ways including inflatable side bolsters, lumbar that moves up and down the seatback to accommodate drivers of differing stature, and a bottom cushion thigh extender. Soft armrests are located on the center console and the door panel. However, the steering wheel is too thick and covered in shiny leather than looks more like urethane. Plus, the door sills are too high and have a sharp edge, making this an uncomfortable spot to rest an arm.
