This design has multi colored blue stripes on one side and a solid royal blue on the reverse side. You can use it on either side. The double layers of terry cloth fabric, not only gives you extra comfort but will keep you from burning your legs on hot steamy days and keep you much warmer on cool damp mornings. It also will help protect you from possible germs on the seat. The weight of the fabric keeps it from blowing off on windy days. No attaching anything, it simply slips over the handles of the cart. Machine wash and dry. Made in U.S.A.
