I decided on Nappa for my 70 after having standard on my 53... I really didnt rate it for the money... I didnt have vented but did have full multi contour and the massaging option...

The armrest and edge pillow really wore very quickly and overall the seat felt less padded... I really use to notice the difference sitting in other 70s with standard seats...

I went back to standard on the 71 I really dont regret it....

But hey!! its all subjective
