Seat comfort Leather sports seats Seat Leon ST FR – too hard

Hi Bin for 3 days proud owner of a Seat Leon ST 2.0 TSI FR. As far as satisfied, except with the comfort of the seats. They are leather sports seats in black with red seams. The seats are basically ok, however after about an hour driving I have slight pain in the area upper thighs / popo. lumbar vertebra support is set approximately to the middle. I sit correctly at my discretion (rather upright, legs not too strongly angled, arms not too strongly stretched) . I’m 190cm tall and rougher (so little self-padded upholstery) The seat support seems to me to be very hard padded, in addition to the rather hard chassis (currently 17 inches with winter tires). Now I’m thinking about how to get the cover a little softer: What do you think?
