Seat covers are great for fabric. I have leather seats which I highly prefer over fabric and they wear pretty well. However, I do keep a towel handy in the summer time. Hot leather and bare skin just don't mix.
I hated seat covers because they never would stay on. One thing I really liked on my old car were some of the seat covers made of round wooden balls. They helped protect the seat, and they were also extremely comfortable.
I have fabric in my car but I am somewhat of a drill Sargent when it comes to what comes into the car with people. Drinks for adults are okay in holders only, for kids plain water and that is it. Snack wise unless it is something easily vacuumed up it does not get eaten in the car. Mine is about six years old now and the seats still remain amazing. Be diligent.
Yeah, I do cover my car daily after coming from office. I used to clean my car on daily basis and after cleaning with cleanser I cover it by car cover. It give life to the car paint so it is essential to cover your car.
Yeah,its very good to save the seat for a log time with the seat covers,now a days in the market there are many stylish covers are also available but some people don,t like this feel un comfort in drive with the seat covers.
