Tell us about yourself!
My first Chevy Equinox in 2005 had something similar, it laid flat in the cargo area, and flipped for two sides - one side carpeted to match interior, the other side hard plastic (which matched interior) so that yo could put wet things, etc on it and it wouldn't damage carpet. You could fit it in - I forget exactly how, with either side up, and it allowed you to store underneath (unseen) and on top! When I bought in 2008, it wasn't there! I think now you have an option for it!
