We’ve had our X1 X-line 15 months now. On the long journey home on collection, I couldn’t get comfortable in the driver’s seat. After a lot of experimentation with the position it improved, but I found seat height and backrest angle was quite critical, reclining the backrest more than I would normally do.
Half the trouble seemed to be that the seat leather (or what’s under it) when new was very tight and stiff. It gradually improved with use and is now fine. In fact I sat in the car for an hour yesterday while Mrs Wigwam had a hospital appointment, without even thinking about the seat.
It is the case that swapping drivers between her and myself needs more adjustment than previous cars, so there is something odd about the seats.
It could be SpinaB that the car you test drove had been well used and the seats had softened up, but clearly you’re not in a position to wait for that to happen. I do hope the dealer can fix the problem for you, but I suspect you may have to get Motability to change the car.
