Anyone here have a child booster seat in back? Dented in cushions?

I am adding my daughter's child seat but had a question. My dad bought a used Camry that a mother owned and she had a child seat in the back and even 3 years later you can still see in the seats where a child seat used to be, like it "dents" into the backseat. Anyway to prevent this without compromising the seat integrity and safety design?

 

I have a small blanket under the car seat, and that seems to keeps the dents out.

I bought one of those seat protectors, haven't tried it yet, wondering if they are any good

 

Use a thick bath towel under the car seat.

 

I have one of those seat protectors in my truck and my wife's car, and they work excellent.

 

Have these under the two in the back.

 

I have the seat protector and it works great. Had to use a chunk of foam pool noodle to level it up.
