With more people using trucks for daily commutes, cabs must be comfortable, and the Sierra provides ample room and nicely built and upholstered seats. Up front, those seats are gently sculpted with firm padding, a wide seat surface and an acceptable amount of support, making for a comfortable ride. Hip and shoulder room is excellent, though drivers may feel as though their feet are a bit restricted in the way they point forward. Extended Cabs have plenty of leg room in back compared to other trucks, though the seat backs weren’t very comfortable. As it is, complaints about the comfort of the Sierra (or Silverado) are few. This is a well-designed and nicely appointed interior, no matter which trim you choose.
