This protector does the job on preventing dents in leather seats.
Remember that these days any type of professional is afraid of a lawsuit, and do not want to use any type of aftermarket product that could interfere with their "professional" installation. That is why no one will approve these mats, or even cupholders on strollers anymore!!!
As a carseat safety fanatic, and being pretty educated on carseat installations I felt confident that I could make a decision if this was inhibiting a proper installation. I see no problems. To be sure the carseat is strapped in super tight, I sit in it as I pull the straps. It doesn't budge one centimeter left or right, or front to back.
This saver was easy to put in the car, and did not need to be adjusted a million times as I tightened in the carseat using LATCH & tether (we use the Britax Marathon). A previous saver bunched and made installation impossible, but this one is very thin, firm and stays put. The add on back was the perfect height, and did not block the tether strap in our F150. It also stayed upright as I put the carseat into place.
This blends in nicely with our black seats and looks good. It's available in three colors - black, tan, and grey. Let's face it - if you're interested in this product it's because you care how things will look long term!
This saver is a great combo of safety and function. While it may not perform perfectly with every single carseat/car combination - if your seat is moving more than an inch in any direction it's not installed correctly whether you are using seat saver or not!
