Ridesafer safety harness/vest for vehicles. Fits children 50-80 lbs who's height is between 45 ans 57 inches. For children 3 years and up. Great alternative/replacement to booster seats, especially for vehicles with narrow seats. I own a single cab truck and this was used for the middle seat where a car seat could not comfortably fit. Can be picked up or dropped off if local. Originally $145 and still being sold online.
