How to Fix a Couch Frame

Looking to know how to fix a couch with broken wood? It usually happens when you sit on your couch cushion, and it sinks to touch the floor. If this has happened to you, remove the sofa cushions and turn them over; Look for broken wood pieces or torn fabrics in the couch frame.

A cracked or bowed-out wood has to be replaced; to do so, you need to consume some time and remove upholstery fabric and dust cover fabric on the bottom; If the wood pieces are broken underneath the couch, springs are not going to be supported by them consequently; so, you need to replace the wood piece and reassemble the couch again.

An example couch-fixing list of tools includes screwdrivers, screws, glues, markers, staple guns, and hammers.

  • Screwdrivers are typically used for screwing and unscrewing operations. A manual screwdriver suffices for upholstery projects, but a powered one is good for you if you crave speed.
  • To form strong glue bonds and create durable joints, a wood glue with strong adhesive sealant can hold wood pieces tightly.
  • When the repair process is accomplished, a staple gun becomes useful to drive metal staples into the job surface. You can check out Ronix staple guns.

Sofa Spring Repair

Looking to know how to fix couch springs? It’s not as complicated as you imagine. Just get your locking pliers ready and let’s go!

Check out to see different types of springs used in your couch, and find out whether your springs are zig-zag type or coiled. Your springs may be bent, broken, or loosened; If they are bent, you may be able to repair them yourself, but loosened springs have to tighten with a few tools; use pliers to twist or bend the springs and turn them to their actual shape. Our recommendation is Ronix RH-1412. In case they are broken, to do a couch spring repair, you need an upholsterer’s help. Be gentler in this step because if the springs are twisted harshly, they snap consequently and you will have to replace them. Most modern couches have zig-zag springs; however, older couches have coiled springs, and some sofas may not even have springs.

Bolt cutters, markers, staple removers, and drills fulfill approximately all spring-related problems.

  • In case you desire to change the springs, the new springs might not fit beneath your couch, so the bolt cutters are helpful to cut the springs.  
  • To mark on the springs and cut them, chalk or marker is essential. Marking on the springs and then cutting them provides you with the right measurement and, as a result, a cleanly done job. 
  • Upholstery staple remover pulls out the staples, you should place the head under the staple, and the staple comes loose and it easily gets out; a wire cutter with an extremely small nose can do the same job too.

The foam might have some dents, and you may want to replace it. In case the batting is worn out, get by with just replacing the batting. To fix sagging couch cushions, we suggest some steps to be considered; the steps are as follows:

  • Firstly, remove the cushions and unzip them from the side
  • Take out the foam; if the foam is wrapped in batting, remove it.
  • Replace the low-density foam with a high-density one.
  • Insert the foam and batting into the cushion to fatten them up again.
  • Zip up and place the cushions on the couch

After you’re done with adding the padding to your cushions, you can either leave the cushions on the frame or secure them with zip ties or upholstery clips. In the end, add extra batting or foam if necessary.
