Follow The Steps Below on How to Upholster a Cushion

1. Measure Cardboard/plywood And Cut It In Size

At first, you have to measure the benchtop you wanted to upholster seat cushion. Take a measuring tape and measure the benchtop length and width.

You can take plywood according to your benchtop size from a home depot. You can also cut the wood at home by yourself. Measure a piece of cardboard/plywood at the same size as the top of your bench and mark it with a marker. Cut the plywood according to this mark with a table saw if you have one.

2. Cut The Foam To Appropriate Size

Now take a foam of a preferable thickness. You can take thicker foam if you want a more comfortable chair or seat. Place the plywood in a corner of the foam and mark the edge of the plywood with a marker.

Scissors will not work for cutting a thick foam. A bread knife is easy to find, or you can use an electric knife if you have one. If you are new to using an electric knife, you can use a bread knife too. It will help you to cut foam with an even edge. Carefully start cutting the foam with a bread knife according to the mark.

3. Cover The Workplace Surface

To avoid adhesive spreading all over the place, you need to take precautions. Take all the things of work aside. Then place the piece of cloth around the work area.

4. Place The Foam

Now put the plywood on the cloth. Spread adhesive all over the surface of the wood. Then put the foam carefully on the plywood and line up the edges. Gently press on the foam to attach the foam to the wood. Wait until the adhesive gets dried.

5. Cut And Attach The Batting

Using batting will cover the uneven side of the foam.  It will also minimize the friction between the foam and the fabric and make the foam from tearing.

Now lay the batting over the foam. Mark the batting 4 to 5 “larger on every four sides than the foam. Then cut the batting with scissors.

Start it from one side of the foam. Spray the adhesive on the edge of the foam and gently press the batting on the foam.

Apply the same process for all four sides of the foam. Attach the corner carefully so that the batting spreads evenly on the foam. Secure the batting on the corner with small folds to smooth the corner. Do not leave it with wrinkles. Finally, trim the extra batting with the scissor.

6. Measure The Fabric And Cut It In Size

Measure the fabric and mark it according to the foam size.  Then cut the fabric to leave 3-4″ extra material around four sides.

7. Attach The Fabric

Put the fabric on the foam. Then turn the pillow upside-down with the fabric. Make sure the material is equal on all sides.

To attach the fabric to the plywood, you need a staple gun.  Now pull the material and place it on the back of the wood. Take the stapler and staple pin on it. Start it from the middle of one side. You should staple the pin 1-2″ away from the edge.

Be careful when pulling the fabric. Pull the fabric gently so that the material does not get weird pulling or pleats on it. Continuously lightly stretch and staple the fabric with the plywood, leaving 3 to 4″ from the corners.

Do not leave space between the two stapler pins more than a few millimeters. If you staple far more than a few millimeters, the fabric can get torn when anyone sits on it or the material gets pulled.

On the other hand, you do not have to worry about the cost. The staple pins are so cheap that you can use as many as you want to secure the fabric.

8. Trim The Corner

Now cut the extra batting from the corner. Trimming the excess materials from the corner help to avoid any lumps when raping the corner.

9. Wrap The Corner

If you follow the simple tricks I did, you will be able to wrap the corners quickly. First, pull the center of the fabric lightly and staple it on the back of the foam.

Then there will be two sides; fold them one by one, and staple them. Secure all three folds with more staples. At last, cut the extra fabric and the batting around the board backside if there is any.

10. Add A Dust Cover

You can use a dust cover to hide the unevenly cut fabric, batting, wood, and staples. Cut a piece of cloth for dust cover at the same size as the cushion, then continuously fold the edge and staple it with wood.

11. Install The Cushion

Now it is time to place the bench pillow on the bench. You can use some screws to place the DIY cushion permanently on the bench.  Take the screw long enough so that it can go through the benchtop and the plywood.

Place the pillow on the benchtop as you want it to place. Then drive a few screws from the underside to the plywood to secure it on the benchtop.
