Grandma be not ready to give up leather seating in she car and want something to protect the leather from damage when a booster seat be install . the Prince Lionheart two Stage Seat Saver seem to be what I be look for . not only be it somewhat more rigid than other seat protector , but it come in tan so that it match my car 's interior . additionally , since I live in south Texas , the lighter color be more desirable for purpose of keep the vehicle 's interior from get so hot . there should be no issue with the seat saver stain the lighter leather black as , base on reviewer ' comment , some other brand do . the Prince Lionheart two Stage Seat Saver be easy to install . the base fill one of the back `` bucket '' seat ; the seat saver 's back need to have be about 4 '' longer to completely protect the booster seat back from come in contact with the vehicle 's seat . further , it would have be helpful if each side of the Prince Lionheart two Stage Seat Saver have tab that extend over the seat back . that would have prevent the booster seat strap from digging into the vehicle 's seat when the booster seat be correctly install . because of the vehicle 's seat depth , the Prince Lionheart two Stage Seat Saver 's front flap do not `` bend '' at the marked area , but still provide a bit of protection to the seat edge . have a little one who like to `` drum '' he foot make I appreciate this feature ; I do wish the flap have be a bit longer and have multiple groove for bend . there be no slide of the Britax Frontier 85 SICT Booster seat which be install on this seat saver ; the booster seat hold firmly in place . the backing on the Prince Lionheart two Stage Seat Saver be a rubber-like mesh , similar to the material use to keep floor rug from slide . since I have not yet have the seat in place during one of we very hot Texas summer , I do not know whether there will be a sticking problem . I will probably remove the booster seat during the summer unless we little one be visit so that I can avoid this potential problem . I would have rate the Prince Lionheart two Stage Seat Saver a 4.5 , if that rating have be available . with the exception of the suggest change , I be very pleased with this product .
