I have a 2017 Premium. Found the seats to be extremely uncomfortable when it was new. Went on a 1800 mile trip then and almost sold it afterward as the seat was so uncomfortable. Tried several different after market cushions, lumbar supports, etc. None of them made much difference. It was the stiffness of the bottom cushions that were the problem for me. After several months use though, the cushions softened from use. Now I find them supportive, but not overly stiff. I guess they "wore in" to fit my butt. Been on several long distance trips lately and the seats are comfortable. Maybe time and use will solve the problem for you. Good luck!
