This kit includes the cover and foam only. It DOES NOT include the pan. You have to use the existing pan to insTall the foam and cover. Complete seats come mounted on an aftermarket pan.
All Standard covers are made of water resistant vinyl. The covers are not waterproof at the seams. If using in a environment where water is a issue wrap the foam with thin plastic before insTalling the cover. Seat Concepts includes a thin plastic sheet with all kits. Water will still be present at seams after rain until the cover dries inside and out.
