I thought I remembered a thread a while back that pondered whether or not the new generation Britax covers were interchangeable. I had both my ma70 and advocate 70cs in for cleaning and thought I would snap a couple pics for everyone. The headrest cover for the ma70, of course, does not go on the advocate, so I left the advocate's on. The cover fits fine, it does not line up perfectly around the adjuster strap because the advocate has the cs feature and the ma does not. It is close enough and still functions perfectly. And Allison Anna makes a cute seat even if the browns don't match perfectly
