If you have a favorite old sofa and you’re not quite ready to part with it, consider giving it new life by retying the sofa springs. This project will take some time, especially if it’s your first time to tackle a project like this. An upholsterer takes several years to master this.
Basically, the way to tie sofa springs is by using a clove hitch knot. The process is repeated per spring coil throughout the entire seat, which is why it is tedious work. Here’s how to tie sofa springs.
- Get the chair you want to work on and have a clear space where you will work. Make sure to put on some workman’s gloves, since you will need to protect your hands. You will also need pliers and scissors to cut off the old springs.
- Remove the upholstery and padding of the chair you are working on. Measure the height of the old spring so you know how much compression you need when you tie it back. Remove the old springs, webbing and old nails. This will leave you with just the frame of the chair.
- When doing this, each row of springs must be comprised of one continuous twine. Also, when completed, the twine should be tight with no slack and the springs should be able to spring straight up and down evenly to allow for compression.
- Measure the depth or the seat, from front to back and multiply that number by four. This is the length of twine you will need.
- Stagger nails or upholstery tack on the front and back frame of the seat, putting two nails in the back and three in the front. Don’t drive the nails in all the way. Secure one end of the twine on one end of the nail with a clove hitch knot and hammer it through. You will now thread the twine back to front, then later side to side then diagonally on each side. This is why it’s called an 8 way twine. This provides the most secure support. As you move the twine, it wraps around each spring.
- To tie the springs on the twine, you will need to make a clove hitch knot. To make it, loop the twine around the spring. Wrap the twine under the spring then pull it back up and push it back down with the first loop behind it. Place the right side of the twine under the left side of the twine, forming an X and pull the left side up to secure it. Click on this link to see an animation: animatedknots.com.
- Repeat the process for all the springs. When you are done, each spring is securely connected to the spring next to it.
This project takes a while but once you get the hang of it, you’ll see that it can be done with a little patience and effort. If you find this project too overwhelming, than consider bringing the chair or sofa in to a professional, but be prepared to pay the premium. Your last resort is to throw it out and buy a new one. The choice is yours.
