No-Slip Chair Pads with Box Corners

Printer-friendly versionSend by emailPDF version

This Sew4Home exclusive design allows you to create a beautiful chair cushion with fancy accent piping and nice square corners but without any beads of sweat forming on your brow. There's no side gusset; we use box corners instead. And the piping is attached as individual strips, so there are no trickhy corners. You'll be sitting pretty in no time. These easy cushions are designed for chairs with a solid back that can't accommodate the more traditional ties used to secure most off-the-shelf chair pads. Our solution: gripper fabric on the bottom to keep the cushions from sliding. Of course, you could use them on any type of chair as an alternative to dangling ties. 

We used quilting weight cotton, which might seem like an unusual choice for something that will be exposed to daily wear and tear. But our samples have easily stood the test of time. This is a S4H Classic Project that has been in use for several years in the home of one of our team members. Because we chose a quality designer cotton, there are no worn spots and very little sun damage. It's one of the reasons we always promote the use of quality fabric. It's not only better to sew with as you put together your project, the finished item retains its good looks. 

Like the placesettings shown above? You can find instructions for both the revisible placemats as well as the super-simple napkins

Our chair cushions were originally made with fabric from the Flora & Fauna collection by Patty Young. This is an older grouping that can be hard to find. As an alternative, we selected two combinations from Caravelle Arcade by Jennifer Paganelli for FreeSpirit which we found in good supply at Fabric.com.  

Sewing Tools You Need

Fabric and Other Supplies

Our sample chair measured 14¾" across the back, 15¾" across the front and 14½" from front to back through the center. The fabric amounts listed below will accommodate this basic size. If your chair seat is quite a bit smaller or larger, make your pattern first, and use it to figure out your yardage.

  • Fabric for seat cushion tops: ½ yard of 45" wide fabric will yield two seat cushion tops
  • Fabric for seat cushion bottoms: ⅔ yard of 45" wide fabric will yield two seat cushion bottoms
  • Fabric for piping: ¼ yard of 45" wide fabric will yield enough fabric for two seat cushions
  • ¼" cording: 3⅓ yards will be enough for two seat cushions 
  • One apx. 12" x 24" package of anti-skid fabric; we used Dritz Anti Skid Gripper Fabric 
  • 1 yard of 18"+  wide 2" thick NU-Foam by Fairfield cushion insert foam (or similar)
    NOTE: NU-Foam comes in various thicknesses and is sold as pre-cut squares or in pre-determined widths on a long roll that can be cut to length. Measure the seat size on the chairs you would like to make cushions for, and check to see if a pre-cut NU-Foam insert would better suit your needs. 
  • All purpose thread in colors to match fabric
  • See-through ruler
  • Long, solid ruler (metal is best)
  • Seam gauge
  • Seam ripper
  • Fabric pencil or pen
  • Iron and ironing board
  • Scissors or rotary cutter and mat
  • Straight pins
  • Permanent marker
  • Pattern paper or similar
    NOTE: This is a great opportunity to reuse other large pieces of paper around the house; newspaper, old wrapping paper, shopping bags.
  • Craft or serrated knife

Getting Started

  1. Make a paper pattern of your chair seat to use to cut the foam inserts. (Our chair measured 14¾" across the back, 15¾" across the front and 14½" from front to back through the center.)
    NOTE: Chairs differ widely, so making a simple paper template, like professional upholsterers do, gets the job done quickly and easily. Fold your finished pattern in half to make sure both sides are mirror images of one another. Trim as needed to insure your final pattern is accurate and true.
  2. Make a second paper pattern to use to cut your fabric. Use the first pattern as your base, but extend 1½" on all four sides. This provides the 2" depth needed for the box corners, plus the ½" seam allowance. (In our sample, that meant our fabric pattern was 17¾" across the back, 18¾" across the front and 17½" from front to back through the center.)
  3. Using the foam insert pattern and a straight edge, trace the shape of your chair seat directly onto the foam with a permanent marker. We made six cushions, so we traced this six times.

  4. Using a craft or serrated knife, cut out each foam insert. We found it was helpful to use a board to help weight and hold the foam as we cut.
    Click to Enlarge
  5. Using the fabric pattern and a straight edge, cut out the cushion TOPS.
    NOTE: Our top fabric had a large directional print, which needed to be fussy cut so it was straight and centered on the cushion. We carefully cut our first piece, then folded that piece in half and used it to align all the subsequent cuts. If you have a particularly large design, you may need to buy extra fabric in order to accommodate the repeat of the design and be able to center your cushion pattern correctly.

  6. For each cushion BOTTOM, cut one strip 12" high x the width of fabric (44" in our sample).
  7. Cut each strip in half. This yielded two 12" x 22" pieces for our sample.
  8. Cut 1½" x width of fabric strips from the piping fabric.
    NOTE: The number of strips you need will depend on the perimeter measurement of your finished cushion (ours was approximately 60") and how many cushions you are making. Figure out your perimeter by measuring each side and adding them all together; multiply that by the number of cushions you are making, then divide the total by the width of your fabric to get the final number of strips needed. In our sample: 60" x 6 cushions = 360" ÷ 44" wide fabric = 8.18. You always round up, so we needed to cut nine strips total.
  9. Cut two 4" x 12" pieces of gripper fabric for each cushion.
    NOTE: This size should work well for a basic chair pad. If your chair's seat is quite a bit larger or smaller, you may need to adjust the the size accordingly. 

At Your Sewing Machine & Ironing Board

  1. Make a ½" double-fold hem along one long edge (the 22" edge) of each cushion bottom piece (we had twelve pieces to finish for our six cushions). To do this, fold and press ½" along the edge, then fold and additional ½" and press again.
  2. Using a straight stitch, sew close to the inside folded edge to finish. Set aside the hemmed panels.
    Click to Enlarge
  3. Using one of the cushion TOP pieces as a guide, lay one cushion bottom piece face up on top of the cushion top piece, matching the raw edges along the BACK edge and centering it side to side. Lay a second cushion bottom piece, also face up, over the cushion top fabric, matching the raw edges along the FRONT of the cushion top piece. For our sample, the two pieces overlap approximately 4".
    Click to Enlarge
    NOTE: This overlap creates the back envelope opening, which allows you to insert the foam. It also means you can remove the covering and launder it after the inevitable Morning-Cheerio-Milk Incident.
  4. Pin securely, then flip the whole thing over, and trim the sides of the cushion bottom fabric flush with the cushion top.
    Click to Enlarge
  5. Repeat for each cushion bottom needed.
  6. Place a 4" x 12" piece of gripper fabric face up on a cushion bottom piece approximately 2" from the long raw side edge and centered top to bottom.
  7. Sew the gripper fabric in place, stitching approximately ¼" from the edge all around. Remember to stop with your needle in the down position and pivot at each corner.
    NOTE: The gripper fabric will not fray, so the edges can be simply straight cut and stitched in place; they don't need to be hemmed.
  8. Repeat for the remaining cushion bottom pieces.
    Click to Enlarge
    NOTE: If the foot of your machine is sticking or dragging on the gripper fabric, you can switch to a Teflon® type foot, such as Janome's UltraGlide foot, or you can try laying a sheet of wax paper on top, which is easy to see through and tear away, but helps a regular foot to move across without drag.


  1. Using a straight stitch, sew all of your 1½" piping strips together end-to-end to create one long strip.
  2. Center the ¼" piping cord on the long fabric strip. Wrap the fabric around the cord, matching raw edges.
  3. Using a Zipper foot and a straight stitch, sew close to the cording to create piping.
    Click to Enlarge
  4. The piping will be sewn to the right side of each cushion top piece. Because of how our cushion corners are uniquely constructed (they are trimmed and boxed), you will stitch a length of piping to each edge individually rather than in one continuous length.
  5. To do this, center a length of piping along each edge, aligning the raw edges. Cut the piping so it starts and stops ½" in from the corners. Pin in place.
    Click to Enlarge
  6. At each end of each piping piece, use your seam ripper to gently peel back the fabric to expose the cording underneath.
    Click to Enlarge
  7. Cut the cord back 1½" from each end - do not cut the fabric. Replace the fabric and re-pin. This removes additional bulk to accomodate the boxed corners.
    Click to Enlarge
  8. Still using a Zipper foot, stitch the piping in place, staying as close to the cording as possible.
  9. Repeat for each cushion.

    NOTE: If you are brand new to working with piping, take a look at our tutorial about how to make it and attach it. 

Assemble top and bottom

  1. Pin each cushion top to each set of cushion bottom pieces right sides together. Be careful with your pinning; you need to make sure the overlapping bottom pieces don't shift when you sew.
    Click to Enlarge
  2. Using the Zipper foot, sew as close to (right on top of if possible) the previously stitched piping seam. This means the cushion top fabric has to be on top so you can see those previously sewn stitches.
  3. Repeat for all cushion tops and bottoms.

Boxed corners

  1. With the cushion cover still wrong sides out, trim each of your four corners.
    Click to Enlarge
  2. Using both hands, pinch and pull apart the corner.
    Click to Enlarge
  3. As you keep pulling, the fabric will begin to make a little peak with the trimmed corner point at the top and the seam lines running down the middle of the front and the back.
    Click to Enlarge
  4. Carefully and precisely, line up these seams. The two seam allowances should fold opposite one another. This will help you align the seams. Remember when we cut back the piping in the steps above? This is why. As you align the seam lines and adjust the fabric folds to make a perfect triangle peak, it is very helpful to not be fighting with the bulky piping cord.
    Click to Enlarge
  5. When your seams are aligned and you have your perfect triangle peak, set your seam gauge to 2" and slide it down the peak about 1" until it hits a width of exactly 2".
    Click to Enlarge
  6. Make a couple dots with your fabric pen or pencil to mark this width line.
    Click to Enlarge
  7. Use your see-through ruler to connect the dots and draw a horizontal line across the peak.
    Click to Enlarge
  8. Check your measurements: you should have 1" to the right of the seam line, 1" to the left of the seam line, and 1" from the top of the peak to the drawn line.
    Click to Enlarge
  9. Stitch along the drawn line. Stitch back and forth along the line two or three times to reinforce.
    Click to Enlarge
  10. Turn the cushion cover right side out and gently push out the corners with your finger to reveal the ‘box.'

    NOTE : You'll notice the piping is slightly offset at the corners. Now, there are bound to be some of you who are driven slowly insane by this off-set. To you I say, 'But you didn't have to make a gusset!!' That's the whole idea of this project. It's a thick and comfy chair pad with nice boxed corners and a lovely piping accent, but you didn't have to use the much-more-complex gusset technique. And, I bet, unless you spend the entire day down on one knee staring at the cushion corners, you'll forget about that tiny off-set in about five minutes. I've forgotten about mine already.

That's  an awesome project.  I have tons of foam I was going to throw away. I'm so happy I saw this. 

I have plenty of chairs that need cushions and plenty of fabric. Thanks. It's beautiful.

@ rachelcortez16@yahoo.com - You're so welcom -- we went to the extra trouble to show how to do the pattern for the seat to try to make the project as flexible as possible for a variety of chairs. Have fun - and let us know how yours turns out

Foam is super easy to cut with an electric knife - you know the one down deep in the cupboard that only gets brought out at Thanksgiving or Christmas.  : )

Thank you for tutorial.

@ Loves to Sew - yes! We've heard before that an electric knife is a good option. Thanks for the reminder.

I bought a piece of foam a few months ago to make a cushion for my office chair but hadn't made the cushion because I wasn't sure how to do it.  Now I can!!  Thanks so much!!

@ Mary H. - Happy to help! This project is really flexible and could be used for all sorts of different chairs.

Brilliant idea to use gripper fabric.  I have new, tied on cusions that still slid about.  A large square of gripper fabric on the chair has solved the problem, without even being sewn on.  And that means I can still use both sides of the cushion pad as top

@ laceandbits - Thanks! We've used these handy grip strips on several projects. It's also great for sofa and bed caddies.
