JJB BFF Changing Mat

Hi, everyone. First time buying a diaper bag and I plan to pre-order the new JJB BFF coming out late September. But before I do, I have a couple of newbie questions.

Does the JJB BFF normally come with the light changing mat or the memory foam changing mat?

Which of the two changing mats is better?

The BFF comes with a memory foam changing pad.

Which of the two is better is a personal preference I think. The memory foam is nice and comfy for baby but is thicker than the light changing pads. I prefer to have a light pad so that I can stick other things (books and stuff) where the changing pad goes.

Thank you, boobearzmama
