Now the front drivers and passengers seats in the MH are real comfortable, except there isn't any lumbar support. I definitely miss it after having it in our cars. Other than buying a higher end coach...
I ordered custom made seats for my coach after yanking out the uncomfortable Flexsteel junk. If you go to a place that makes captains chairs, you can order the type of foam, etc, to make the seat just what you need for a comfortable ride. I eventually had spinal fusion surgery and now the seats are even more comfortable.
