Taken out of the package, no backing board included. Please screenshot the installation photos. I've lowered the price accordingly. Easy to install, just cover the seat. Compatible with headrests that can be removed. This type does not have strings to secure the seat bottom. Since it's not thick, the pattern underneath may show through if there's already a pattern on your seat. The black lace part has no fabric, so the color underneath will be visible. Only one piece. No set of two available. Please refrain from price negotiations. Bundling is negotiable. #PurpleCarGoods
