I love my current E320cdi estate, it's the sports version and is fitted with sports seats. Now, I'm sure these are supeb for the average driver, but I've had a spinal fusion carried out and am finding that the seat is making my lower back and thighs ache on longer journeys. The main problem seems to be not enough lumbar support, coupled with side bolsters that are a bit too supportive for my lardy *rse. Now, I did think about buying an aftermarket seat, but the only one I can find that's approved for the car is a Recaro 'Ergomed', which would cost around £2500 to have supplied and fitted. Bear in mind, that's for ONE seat only! So, I'm looking for any suggestions that might make my life more comfortable. Is there another type of OEM Mercedes seat that could be used? If so, where to look for them? Is there a custom upholsterer in the country who could re-jig my current seats somehow? Or should I just change the car? Currently, the latter is seeming the more attractive option! If I do change the car, what seats were available that might be more comfortable? All suggestions will be gratefully received!
