Obus Forme Ergonomic Seat Cushion
This cushion is great for long trips.  It distributes your weight evenly while sitting for long periods of time so that your back doesn't start to get tired.  I wouldn't drive  anywhere without it.  It is light weight and easy to store when not using.[[ASIN:B000FJS6KC Obus Forme Ergonomic Seat, Black]]
