The Snooze Control is a car seat cover that allows the person in the front passenger seat to sleep comfortably and safely.  The bottom seat portion of the cover is filled with a fluid that resists rapid motion -- we used a pillow filled with oobleck.  When you are sitting in the car, the pillow is sort of like a waterbed (your legs sink into it), but if you are in a  collision it hardens up and prevents you from sliding into the dash or door.  The Snooze Control has multiple velcro straps, making it easy to put on and off. It has a neck pillow with a slip on it, which helps with head support. The slip of the neck pillow has velcro on the back, allowing you to adjust the neck pillow so that it is comfortable for all sizes. Another safety feature is the seatbelt. The seatbelt is like a baby seatbelt -- you put your arms through it so that if you are in a head-on collision or rear-end collision it stops your upper body from jerking up. The seatbelt and slip are anchored to a sturdy part of the car by a strap with a clip.
