I've just bought my S-Max 


I don't want everything in the back just loose, so I need to think about boot safety solutions. I don't know where to start and some of the Ford options are for the continental 5-seater version.
So what has everyone else got - tie down nets/ dog guards etc. Are there any dog guards that would still allow you to fold down the middle back seat (for carrying long stuff without having to remove the whole guard.
Does anyone have the retention net? And how much do they all interfere with your rear visibility???
Thanks (i hope you all know what I'm talking about!)
