There has been quite a few comments about the massage seats feeling less padded. I'm with SoySauce cause my wife thought it was just my flat ass, lol.
It makes sense they can't have all the padding if the rollers are supposed to come through the bottom. I guess turn 'em on more to relieve the feeling from them being thinner. After getting off the train those seats are clutch for the quick drive home to get the blood flowing again.
