I'm a bit anal about minor wear issues on leather seats . My 2011 car was showing signs of slight scrubbing where a previous owner's backside slid over the side of the seat upon entry to the car, also the drivers seat had sagged a little even though the car had covered only 10k. I decided to swap the seats around together with associated drilling new seat belt stalk mounting points on each seat and also drilling the floor for new mounting position for the seat rails (this is required due to the offset rail mounting position on the seat assembly).
As part of the project I decided to have the drivers seat squab repacked, my local trimmer of 40 years experience did it for £30 and did say the original foam was a bit "lightweight". The result is superb, a nice firm seat and with more squab height gives increased support from the sides. Only problem is that it's so good i'll need to get the other seat done so that it looks as good and matches the comfort of the other seat. By the way I have suplex front end and have just installed bilstein shocks on the rear the latter provided a marked improvement in ride comfort. Oh by the way I also installed wedge the length of the seat rail to provide uplift of about 50mm at the front of the seat for thigh support, I always felt as though I was sliding forward with standard seat lack of for / after inclination.the seats have been secured to the floor/ chassis with 100 x 8mm s/s button socket heads cut to suitable length and nyloc nuts. By the way the seat belt guide mounting bolt on the seat can be installed either side of the seat, the mounting hole is upholstered over where not used.
