If you've been considering a cushion in the past or already have one, this is a great buy because of it's size. It helps considerably for those that have bad backs as well. For the price and options (A VIBRATOR POCKET!) you can't go wrong! That's it, I'm going to make a car seat cover that I can put vibrators in! ...What's that? ...They already have them? ...Well where do I sign up?!?!?
