I am now at 165.9+K on the clock. I would like to know how are your guys seat cushions holding up? Mainly on the driver's seat. I don't know maybe my mind is playing tricks or also my advance age (72+) that I feel the cushions are not plump as they use to be. But on the other hand, maybe also this is the time when all these times that my SO always chews out my ass to the bone that I do not have the meat left to my rear end?

Does weather also play a factor on cushion deterioration? Car always parked in shade/canopy. But would temperature changes affect cushion deterioration?

Wondering if a reputable upholstery shop would be able to replace the cushion? And what type of oem cushion as replacement?

Thanks.
