The cushions can wear down due to wear and tear.You can either buy a new couch or fix it up.To figure out why the couch is sagging, you need to inspect it.It could be a matter of old cushions or a broken frame.
Step 1: Why is your couch sagging?
A bad frame, worn out cushions, or old springs could be the cause of a sagging couch.You're in for an easy fix if the problem is the cushions.You may have to replace the springs or the frame if the cushions seem fine.You may need to replace the entire couch if the damage is high.
Step 2: Take pictures.
Take pictures so you have something to refer to when you take your couch apart.If you can, take the pictures to the furniture repair shop and see if they can help you figure out the problem.
Step 3: Look at the frame of the sofa.
You can see the bottom if you turn the couch over.There are torn fabric and broken wood.If you see cracked wood or wood that isbowed out, you need to replace it.It can take a long time to take off most of the upholstery fabric.The fabric on the bottom may have to be removed to inspect the springs.Don't rip the fabric.
Step 4: Take note of the springs on your couch.
Some couches have zig-zag springs.coiled springs are used on other couches.Determine if the springs are bent or broken.You can fix the springs yourself if they are bent.If your couch is broken, you should bring it to an upholstery shop.Older couches have coiled springs, while newer ones have zig-zag springs.Depending on the frame, your couch may not have springs at all.The space beneath the cushions should be checked.The slats or straps on the couch may have snapped.
Step 5: The cushions should be firm.
You may need to add more filling if the cushions feel soft.Remove the insides of the cushion cover.It is a good time to wash the cushion covers.
Step 6: The batting and foam need to be inspected.
Batting is used to give the cushions a smooth appearance.It can be made of cotton or wool, but can also be a blend of materials.You may need to replace the entire cushion if the foam has dents.If the foam is good, you can just replace the batting.
Step 7: The foam or the batting should be replaced.
Determine what needs to be replaced.At an upholstery supply store you can buy both foam and batting.If you want, you can change the material of your couch cushions.You don't have to use foam.If you want, you can find cotton, down, or old clothing.The material you use will affect how soft the couch is.You want to make sure you like the firmness of the cushion.Consider how long your materials will last.foam padding could last you for a long time, even if some materials don't hold up well.
Step 8: You can layer the batting over the cushion filling of your choice.
It is important to use "sheets" of batting.Wrap the cushions a few layers thick and cut to the seat size.If you don't smooth it over, you may create a weird seat.
Step 9: The cushion covers need to be replaced.
You can put your cushions back in their covers after you've repaired them.The only issue with the sagging couch was the cushions.The frame should be inspected again if the couch is still sagging.
Step 10: Check the slats.
If the wooden boards that support the couch frame are broken, you will need to replace them.Take a note of how many slats you need.It is possible to buy material at a hardware store.Take a slat to make sure you get what you need.You could put a piece of plywood between the frame and the cushions.This isn't a permanent solution, and it could make the couch a little more firm.Wood glue can be used to seal the ends.To secure the beam in place, use a staple gun, a hammer, and thin nails.
Step 11: Fix springs that are bent.
You can bend the springs back into the shape of the other coil if they are twisted or bent.Take your couch to a furniture repair shop if you need to replace the springs.A spring stretcher is a specialized tool for replacing springs.
Step 12: Remove broken wood.
You'll need to replace the wood if the wooden frame is cracked or rotted.It is possible that the wood used to build your couch is plywood.If this is the case, you should replace it with hardwood.The wood you're replacing has fabric attached to it.Do not damage the fabric.The springs that are attached to the frame will need to be removed with a special tool.This process can be dangerous.Take the wood off the couch after the springs and fabric are removed.
Step 13: Attach the wood to the couch.
You can replace the broken boards with your new wood by using a staple gun or hammer and nails.Put wood glue on the board and let it dry.Attach the clips to the wood.The use of a spring stretcher is possible.The clips should be secured with new screws.
Step 14: The upholstery and fabric should be put back on the couch.
You can put the upholstery back on the wood with the frame replaced.Attach the fabric to the frame using a staple gun.
