How to make a DIY seat gap filler for your car

Supplies:

  • Foam pipe wrap insulation or foam pool noodle
  • Serrated knife, box cutter or sharp scissors

Instructions:

  • Foam pipe wrap insulation is an inexpensive and ideal option for a DIY seat gap filler. These foam noodles, commonly used for pipe insulation, can be found at hardware stores in various sizes. Select the size that best fits your car's seat gap. The other option is to use a foam pool noodle, which is equally affordable and available in various sizes.
  • Using sharp scissors or a box cutter, cut the foam noodle to match the width of your seat gap. If dealing with a narrow gap, consider cutting a pool noodle in half lengthwise to create two smaller pieces.
  • Insert the cut noodle into the gap between the seats or the seat and center console. Push it down until it sits flush and is out of sight, effectively closing the gap while remaining discreet. 

More DIY seat gap fillers 

Looking for more easy options? Consider these alternative DIY seat gap fillers:

  • Foam: Cut a piece of foam to fit the width of the gap and slide it into place. Opt for a dense foam for enhanced durability.
  • Cardboard: If you're on a budget, cut a piece of cardboard to match the gap's width and slide it in. Folding the cardboard in half creates a thicker piece for better gap coverage.
  • Rubber: Rubber water pipe insulation is similar to foam pipe insulation, but slightly more pliable, allowing it to slide into tricky seat gap spaces easily. These can be found at hardware stores in various sizes. Select the size that best fits your car's seat gap.
  • Purchase a Seat Gap Filler: If the DIY route isn't your thing, there are plenty of affordable seat gap fillers and organizers available online. These purpose-built solutions prevent small items like sunglasses, wallets or keys from getting lost under the seat and even offer organization solutions, too.
