How To Tie Springs

Tying upholstery springs can be a complicated affair, and it is a skill that takes years to perfect. Coil springs should be tied down firmly to prevent them from moving sideways out of position, with the firmness of the spring determining the amount of compression needed upon tying them. The springs must also be tied to the same height so that their upward expansion is restricted. If you are serious in learning the fine art of tying springs, here is a straightforward guide in doing it:

  1. Prepare the materials: spring twine, ruler, protective gloves, shears, hammer, spring tacks, pen and paper.
  2. Remove the fabric and padding. Measure the height of the springs before removing the existing ties to determine how much to compress them with the new ties. If the springs have different heights due to wear, compute the average. Measure the distance across the frame lengthwise and crosswise as well, and write it down.
  3. Unhitch the old ties one at a time. Use the gloves to prevent injury from sharp edges. Proceed down each row until you reach the last, then pull out the old tacks.
  4. Sever a piece of twine for the first row of springs. The twine length should be four times the length of the back rail to the front rail. There should be one piece of twine for each lengthwise and crosswise row of springs.
  5. Hammer two tracks into the frame for each row. Align them with the center of the springs. The tacks should be half an inch apart and embedded only halfway into the frame.
  6. Knot a clove hitch at one end of the twine. Loop this around the set of tacks then hammer the tacks all the way in, fixing the twine in place.
  7. Push down the edge of the spring closest to the tacks then loop the long end of the twine around the top of the spring. Pull the twine and tie it to the top of the spring with an overhand knot, then tie the other side of the spring with another overhand knot. Work your way down the row until you reach the last spring. Pull the twine to compress the entire row of springs to the necessary height. Keep the twine taut all throughout the tying process then secure it to the frame with another set of tacks. Trim any excess twine.
  8. Repeat the process with the next row of springs until you reach the back row then do the same for each column of springs. There must not be any slack in the twine at any point when any row of springs is fully tied.
  9. Replace the padding and the fabric. Test the result for evenness.

Be ready to redo the ties several times until you get the method right. A spring is in the correct position when it is standing straight, although the top of the edge springs may be slanted. Always use spring twine for this work. Don’t rush your work, as this will affect the lifespan of your chair or couch. And finally, dispose of old material properly and store away the tools and materials.
