Save the leather seats

6months pp. FTM. Is there a way to save my leather seats? I removed the car seat base from my car and placed it into my husbands truck. Well I saw that the base has cause indentions on my seats. I plan on trading out of my vehicle into a larger vehicle and I don't want my seats to look like that otherwise I won't get as much money as I'd like when trading out. Is there something I can place in between my seats and the car seat base to prevent from any more indentions occurring?
