1

Identify The Problem

In order to figure the solution out, one needs to first know what the problem is. The problem causing the sag in a sofa could mainly either be the cushions or the structure of the sofa i.e. the springs or the frame depending on the type of sofa. You are just lucky the cushions are at fault because that is easier to fix. The latter might require some digging into, but nothing you cannot handle. Remember that sagging couches are very common.

Select the Sofa Size According to the Doorway Size

Once you have identified the problem, you need to find a solution for it. We have sequentially jotted down all of the possible forms of problems that can occur in different components of the sofa, and then their possible professional and DIY solutions. Today fixing problems are relatively easier due to access to multiple online platforms. You can get in touch with experts online and get answers to all your queries.

Sofa Cushions

If the problem lies in the cushions of the sofa, the solution is simple. The sofa cushions usually have fabric covering, filled with materials like cotton, polyester, etc. With time, as the sofa is used, this filling does not remain as full which makes them feel mushy.

To fix this, you can take the easy way out and just order new cushions from a couch manufacturer and be done with it.

Restuffing the Cushions

The cost-effective DIY technique is to first check if the cushion covering has a zipper. If it does, great! Open it up to expose the filling inside. If not, the cushions (not made of leather) will need to be cut open and then sewn back up afterward if they are attached. Identify the already existing filling material and either add more of it or, remove all the existing one and upgrade. There are a few options out there for example; 

Polyester Fiberfill


It works well to make loosely filled cushions fuller.

Quilt Batting


It can be wrapped around the filling that has lost shape, which is then wrapped with the cover. This is used to make the cushions firm.

Foam Padding


A full foam padding lasts longer and feels firmer and better. For this process, the foam pieces are cut in the shape and size of the cushion. The fit should be snug inside the cushion so the measuring should be careful. It can be cut bigger at first and then cut down according to need.


While choosing a foam, get one with a higher density as it ensures a longer life.

Upholster Your Sofa

However, if none of this works for you, you can go for a completely upholstered look for your sofa. This will require a bit of work but will leave your sofa looking new. Check if your sofa is one that can be upholstered. Take pictures of the couch at each step so you can put it back together easily. It is very necessary if you do not want to be left confused. It needs to be repeated throughout the whole process at every step. Carefully take the couch apart. It needs to be done in the following manner;


1. First, take all the back cushions off the sofa.

2. Then take the seat cushions off.

3. Flip the sofa and take the covering along with any other upholstery fabric at the bottom, off.

4. Remove the armrests and take off the covers.

5. Take off the remaining sofa fabric covering the frame.

In- depth Process


If the old cover fits well, you can use it as a reference for the new covers. Get new cushion fillings for all the cushions. The high-quality foam will be better than a cheap one for a lasting solution. Using the old cover and the pictures as your guide, roll out, and cut the new fabric. After cutting the fabric for all the sofa components, sew it together and staple it along the edges of the frame of the sofa. First attach it onto the sofa deck, the inside arms, and then the inside back. Hold the fabric taut and be careful that the fabric should be snug otherwise it will get loose faster.


Once the fabric is all wrapped around the sofa, sew the cover over the cushions. After this, attach the outside back and the outside arms.

Cinching the Cushions

You can also fasten the cushion cover using buttons. For this, uncover the cushion first. The buttons need to be sewed on the sofa with the same thread so that they are cinched and tightly fastened with the cushion. The number of buttons used depends upon the size of the cushion. The cinching will remain longer if it is done strongly between the buttons.

Repairing the Webbing

Usually, the bottom layer of the sofa comes with jute webbings that loosen with age due to the springs pressing down on them. One remedy you can apply to repair them is to tighten them. If your webbing is still intact then you will have to take off all the staples from one side. Pull that loosened side towards yourself, stretching the webbing taut towards yourself. Staple it again, preferably in the center of the wooden frame rather than the edge. Fold the excessive webbing like a hem. You may need four or five staples for a piece of webbing. You can also hammer the staples or tacks for extra strength.

What if Your Webbing is Getting too Weak?


If you think your webbing is getting too weak, then you may need to set up an all-new web. Take reference from your older webbing, weaving the strips of fabric in a check pattern.

Sofa Seat Savers

Sofa Savers are a good hack for light problems like out of shape cushions, slightly damaged springs, and frame. It does not solve major problems but just adds a little support or lift. Simple in installation, the saver just needs to be laid under the cushion. It is a foldable slat-like construction made of PVC and hard fiber filling and is flexible in size.

Sofa Springs

If you do not see any problem with the sofa cushions, then you may want to move on to the structure of your sofa. Sofa springs can get weaker with time. To inspect the springs, you will need to remove the fabric covering under the cushions of the couch, by removing the staples on the edges with the help of pliers. Staple the fabric back after you are done. There are two kinds of sofa springs; coil springs and snake springs.

Coil Springs


Older couches have coil springsthat may get twisted, bent, or broken.


They can be a little tricky to fix. (Warning:Use gloves and eye protection.) Once you have exposed the springs, check to see if they are compressed or stretched. Stretched springs will usually plop out of the sofa. You can compare them with a new spring for this purpose. They can be bent back into original shape using pliers although, if handled too harshly, the spring can break completely.


If that fails, then the springs may need to be changed altogether. Identify the worn-out spring and cut the ties and metal wires to remove it. Put the new spring in its place and fix it using a strong piece of string or screw plates.


Check all the springs, for any loose, misaligned, or flattened ones. Reconnect them tightly to the frame or screws.

Snake Springs


Newer couches have zigzag-shaped snake springs. There can be several problems with these kinds of springs.


The springs may have come off their clips. The springs may be looser or tighter as compared to one another resulting in an unsynchronized movement or some springs may be broken. For longer sofas, the central portion of the springs may have become weaker with time. 

If the spring has come off its clips, or if a clip has fallen off, then here is what needs to be done. You will need a pair of pliers to bend the spring back into the clip in the first case. If a clip has fallen off, then you will first need to buy a clip resembling the other clips on your sofa. Once you have got the clip, fix it into the sofa in the place where the original clip should have been, with the help of screws. Bend the spring into the clip and you are good to go.


In the case of an unsynchronized movement, you will need to link your springs with each other tightly with a strong string, rope, or zip tie. This will distribute the support evenly.


If any spring has broken, then you need to get a replacement spring. Luckily, the replacement spring is easier to latch onto the clips.

Sofa Frames

Every sofa is made different, but it is sure to have some kind of support frame, be it wooden or metallic. To fix the problem in your sofa, you need to first study it. Expose the frame by removing the covering and understand how it's built. Check your frame thoroughly and look for any wobbly or broken areas.

Metal Frames


If you see a bent metal frame, then try straightening the bent parts.


It is quite rare for a metal skeleton to break. In such a situation you will have to weld it back together.


If you want a long-lasting, permanent solution, then get parts replaced for proper support, for more informations read the guide about how to replace a couch.

Wooden Frames


The sag occurs in the center of the sofa where the frame is weakest.


Usually, it may be one wooden slat that has given in from the rest of the sturdy frame and the entire slat may need to be replaced. It can be temporarily fixed by wrapping the wood for better support but in the longer run, the problematic slat needs to be removed and replaced with a sturdier slat of the same wood.


When a sofa frame and slat are one piece then plywood can be used to save the sofa. Take the cushioning off the sofa. Cut a plywood piece of the same size or slightly smaller, as the bottom of the frame. Place the plywood on the frame and tuck the sofa cushions on top of it. This will help make that part sturdier, allow extra support, and create a firmer landing for seating. If the landing is becoming too firm and uncomfortable to sit on, foam sheets can be cut up to size and placed on top of the plywood to make it softer and give a better comfort. Metal brackets can also be used as support.

Sofa Mantenaince

Sofa springs can be damaged with time if the sectional sofa or sofa bed is subjected to rigid use and they can cause a saggy sofa.

The best way to keep the sofa cushions from being flattened, they should be flipped occasionally.

However, if you are a careful user and your sofa is still sagging, don’t be too hard on yourself. The material used on your sofa might not have been too durable or it could just be due to the passage of time. If you want your sofa set to last for 5 years or 10 years, then constant upkeep is very important. If you keep on delaying an issue, it will over time turn into something big. Keep investing your time and effort into your sofa overtime or for that matter any furniture piece, to increase its life.
