This is a colorful blue stripe with a reverse side of solid blue. Can be used on either side. There is no attaching anything, it simply slips right over the handles of the cart. The weight of the double layers of terry cloth not only provides extra comfort but will keep the seat cover from blowing off on windy days. So no more sitting on a hot sticky seat on those humid summer days or sitting on a cool damp seat on those chilly spring mornings. And don't forget about that extra protection it provides from any germs on the seat. Trims may vary depending on availablity. Machine wash and dry. Made in U.S.A.
