The leather surfaces of my front seats feel very rough/coarse to the touch and overall, the material feels very hard. The back seat doesn't seem to have this problem.

I tried applying Lexol Leather Cleaner and Lexol Leather Conditioner several times, but it hasn't helped. Is this just how these seats are or can something be done about this? Maybe I need to use a better conditioner? Any suggestions?

This is an '02 e39 with sport seats. I bought it 1.5 years ago and it's been like this since I bought it. Up until last month, I was living in FL, so I thought high humidity would actually prevent leather from becoming so brittle, but I guess this issue has nothing to do with humidity.

I have used Leatherique on my 1994 325is and it does a great job of re-conditioning and adding some softness to the leather-making it more supple.
