The idea is great - but doesn't work out too well. When placed between my two kids' carseats in the back, the only part that actually functions is the main compartment where things can fit. The side pockets are inaccessible (I have a Mercury Mariner SUV for reference) and the cup holders don't fit any size kids' cups or water bottles that I tried. This item may fair well in a larger SUV with a wider backseat, but it didn't work for us. And the cup holders were so small, I don't know exactly WHAT would fit there besides a skinny disposable water bottle?
