Automotive Seat Repair

Your vehicle is an important part of your day to day life. Since you depend on it to get you to and from work, school, or errands on a daily basis, the seats need to be comfortable enough to accommodate all that driving. If your seats are showing signs of wear and tear, foam is the best way to fix them for a renewed sense of comfort. A car with an uncomfortable seat is never fun or safe to drive so it’s important to take care of this matter as soon as possible. Let’s take a look at using foam for automotive seat repair.

Why Foam?

When it comes to automotive seat repair, there are a few reasons why foam is the ideal candidate for replacements. For starters, most car seats are made with foam as their cushion base which provides the support and softness you need for sitting. Foam is also ideal because you can glue it in place to handle holes in the seat without replacing the entire seat cushion. Foam is an affordable solution available in a range of types and densities to suit any preference. It is also easy to work with in terms of measuring, cutting, and gluing in place for added convenience.

Items Needed

When attempting automotive seat repair with foam, there are a few tools of the trade you will need before you get started. These tools are relatively easy to find at most hardware stores or foam suppliers.
This is the tool you will use to remove the cover to access the area where the foam will be placed.

High-Density Foam

A higher density foam will give more support while still offering ample cushioning for comfort. The amount of foam you will need will depend on how big of a repair you are making, but it is always better to buy a little more than you need than to not have enough for the scope of the repair. It is best to buy larger sheet foam so you can cut it to your exact specifications.

Measuring Tape

This is important for determining the size of the replacement foam as you make your cut.


You will need a marker to outline where you will cut the foam based on your measurement.

Sharp Blade

A blade is used to cut the foam from the sheet so you can add it to the seat.

Spray Adhesive

The spray adhesive will be used to secure the foam to the rest of the cushion for a secure hold. You should make sure you use spray adhesive intended for foam to get the best hold possible.

Fabric Stapler

This is used to hold the fabric in place after you pull it taut over the seat cushion once more.

How to Repair Seats with Foam

Once you have assembled all the necessary tools for the job, you are ready to get started. This is a relatively easy and quick task so it shouldn’t take more than 30 minutes to complete.

Step 1: Removal

The first step is to remove the fabric or cover from the car seat. The way you do this will depend on your car seat since every car is different. While some cars may have removable seat covers, other car seat covers will have cloth sewn over the seat area which you will need to remove with the seam ripper tool. When using the seam ripper tool, use care not to tug on the fabric so you can salvage it later. Take the cover or fabric off so you can see the area of the cushion you will be working on.

Step 2: Measure

The next step is to take some measurements. Using the tape measure, take measurements of the hole or area of foam missing from the cushion that you need to replace. You should also measure the thickness of the seat cushion. If you need to glue the sheets together to accommodate the thickness of the seat, you can do so later.

Step 3: Mark

Next, you will need to mark your measurements on the new foam sheets so you know how much you need. Make an outline to match the hole in the seat cushion but make it about 1 inch more than you need on each side. This allows room for any errors and you will trim it down later as needed to match the exact hole in the cushion.

Step 4: Cut

Once you have marked the foam, it is time to cut using the sharp blade. Make sure you cut on a surface you don’t mind cutting up when the blade goes through the foam.

Step 5: Place and Glue

Now that you have cut the foam out, you can spray adhesive to the back of the foam and quickly place it in the hole, trimming off the excess as you go. Make sure you don’t spray the glue on the excess before placing it so you can trim it down with ease. Finish trimming all the excess until it is smooth and then press the foam firmly in place, holding for a few minutes to provide a secure hold. If the foam feels loose, you can add some extra foam or extra spray to get a better hold and fit.

Step 6: Recover

Once the glue is dry and you are satisfied with the job, you can recover the seat. If it is a traditional seat cover, simply place it back on the seat and you are done. If it has a seam, you will need to pull the fabric back in place, and staple it down with a fabric stapler. If the fabric has a hole, you will need to replace that during this job with either a new seat cover or new fabric.

These are the tools and steps for replacing a foam car seat. Foam is a great asset for this job and can help restore your seat in no time. It’s an easy task sure to give your seat new life for maximum comfort and support!
