2010 rear seat back damage?

[Marvintpa]

For those who own the 2010 hatch, have you noticed any/much damage to the backs of the rear seats when you load in heavy items with the seats folded down?

This is the way my car-to-be will be 99% of the time, so just wondering.
The frames of the seat backs don't seem even and flat (like on a Matrix, for example) so I'm just wondering.
My goalie bag and dive gear can get kinda heavy and this might not be the best choice of car if they'll destroy it.

I haven't noticed any damage, and I'm always folding down my rear seats. However, if I ever plan on placing "anything" on the backs of my seats, I always use a towel or blanket. Regarding the Matrix, if I'm not mistaken, the backs of their seats are covered in hard plastic? So in your situation, I guess that would make it more practical.
