Is there any one having the same problem as me. I am around 16.5 stone and after around 30 minuites of driving I finf that there are 2 metal parts that are part of the seat frame sticking up into the seat.
I fear I may way quite a bit more than 16 1/2 stone, but have not experienced any problems like that. I find the seats very comfortable and well supporting. A would suggest taking it back to the dealer for them to have a look, but if some skinny mechanic seats in it, he's just going to say that he found no problem!
I'd say that I might weigh a bit more than that, I'm also 6ft 2, quite a big guy; and I find the seats comfortable and very supporting. Not been in the car for more than about 3hrs straight; but that was enjoyable and I felt fine.
