My m sports seats were a lot more comfortable after I discovered the side bolster adjusting rocker switch, the previous lady owner must have been a little less broad than me, ahem!

Must admit it takes a while to adjust them just right but I have two settings programmed in. One for normal driving and one for long distance motorway stuff. Both comfy
I already have a damaged sciatic nerve which is why I traded in my Lotus Elise for the Z4 ... collected it from the UK and drove it to the South of France without any problems at all. Maybe we all have different leg problems so the seats suit some and not others ... I'm OK with mine! ...
