Hello guys

I have a question
Im buying a 2013 C63 im a newbie the seats are really tight. Passenger seats are even tighter. They only inflate and deflate. The guy selling me it told me that the seats's bolsters can't move apart from each other. Is this true? Please somebody help me. What are the functions of the seats exactly. Thanks

 

The C63 bolsters are fixed. They have an airsac in the bolster which can inflate or deflate to "hug" you better. Also there is adjustable lower and mid-back lumbar. The seller is correct, the bolsters cannot move apart from each other.
