From what I understand the new HE seat leather is similar to the pre-2016 leather. Having had both the new HE and a pre-2016 LC would you agree with that? As silly as getting hung up on seats may be, the amount of seat time it takes crossing the country bumps them up in the priority list... especially as I have gotten a little older. Our current Navigator seats are, simply put, amazing. I don’t expect to achieve their level of comfort but I do appreciate supple, comfortable supporting seats.
If the new HE seats are similar, then they should be durable. I never got to see pristine seats from the 2011 as I bought when it had 105k on the clock. But one of the reason I bought the 2011 was because the seats were in solid condition (previous owner didnt slide off the sides like most people do). Cushion-wise they both felt/feel great. I would argue the new HE seats feel softer to the touch though. Just my uneducated opinion.
