Nick W, Dave W - you guys are stars!
I cannot quite stay comforable for 2hrs+ in my (standard reclining) seats of my 4/4. More support is needed in the lower upright section.
Since my wife has an unused orthopaedic lumbar bolster (from when she had an Audi - the sports seats gave her sciatica) I shall adapt this. The support is made of shaped high-density foam so I shall cut it up and see if I can use a section to modify the profile of my 4/4 driver's seat. I would never have guessed the backrests can pull away from the main body of the seat.
