We're all shaped differently, so a comfortable seat for you may be an aching back for someone else after a long day.i have an 08 and my wife an 2011. I love the seats and the ride. Not sure what you re experiencing.
Those sheel-mann seats look nice and I wonder how expensive they are, but if they can do custom seats for just about any vehicle (and including a Land Cruiser / LX). Even if they cost a few thousand per seat, it's likely to be more cost effective than changing vehicles and should also result in a more comfortable seat in the end as it will be tailored to the requirements of the specific person. The trick may be in figuring out which option is best.
