Do you want to use your Mazda 6 to stow luggage or gear for a road journey? If you do, you may encounter problems like no enough room for both people and items. What to do with the situation? Is there any solution to solve the trouble without a huge investment or a complicated installation process? We are here to help, no worries. 

Your Mazda 6 is a midsize car with 14.7 cubic feet of trunk space for loading stuff; however, you can fold down the 60/40 split-folding seats to generate more room for carrying large items. It seems the problem is solved by finding the foldable rear seats, but it isn’t. If you usually travel alone, you can fold the rear seats down to create more loading space for bringing all the essentials on the roads. Your Mazda 6 can carry up to 5 people, so you cannot fold all the rear seats down when you have more than two travel companions.
