It might be they just don’t suit you, being a seating engineer I would agree with above, it’s often down to posture and how you have adjusted it. Many recline a seat to far or slouch and don’t get the right lumbar support. Personally I find them comfortable, their shape and form feels pretty good to me so I don’t think their is any inherent design issues. Experiment with back angle, steering wheel adjustment as well, don’t stretch to reach anything etc. Make sure your ass is pushed well back into the back of the squab and cushion bite line. If all else fails buy a Volvo .. 😀
