Sometimes a new seat just isn't in the budget. Here are some great options to bring new life to your truck seat and continue to get the miles out of it. We do advise that you check the support of your cushion and replace it if it has broken down and is not supporting you anymore.
Even better, buy a cover to protect your seat from the begining of it's life - especially in outdoor environments. The Coverall product is for high back seats and fits most brands.
