Why Do Your Couch Cushions Sag Or Sink?
Sunken sofas may be due to broken frames.
First thing first, we’ll walk through the primary reasons for sofa cushions sinking or sagging. That makes sense when you’re seeking ways to fix the issue.
Broken Frame
Once you notice the sign of sinking, the immediate step is to inspect the sofa frame to see if it’s broken.
Should your couch be made from wood, the frame or board supporting the cushions might break because of the weight loaded on it for a long time.
If that’s the case, you will need to replace the damaged frame using cardboard or plywood.
Uneven Weight Distribution Throughout The Cushions
Normally, you’ll be used to sitting on an area of the couch more often than other parts. Yet, this act is liable to induce uneven weight distribution on cushions.
Over time, they will start to sag. The only solution to make your cushion solid again is to get new fiberfill or foam inserts.
Sleeping On The Couch
It’s hard to resist falling asleep when watching a late-night show. That’s a normal habit among sofa owners.
Yet, this habit will put stress on your couch springs over time, inducing them to worsen.
Once these springs weaken, they’ll no longer be able to provide the cushions with strong support, hence leaving them sagging.
Things to Put under Couch Cushions for Support
We’ve talked about the possible causes of sunken sofas. Let’s delve deep into its structural integrity.
Sometimes, you can prop up the cushion by simply placing the right supporter underneath it. Sometimes, that item can go inside the cushion beside the stuffing that is already inside.
In our experience, the two methods and five items below will provide your sofa’s structure an effective boost to stay fresh and in good condition. So it’s time to study how to keep your couch cushions from sinking.
1. Restuff The Cushion
Restuff the pad to make it new, firm again.
Restuffing is among the best methods to keep your couch cushions from flattening and sinking. Look at either side of your cushion, and you will see a zipper. Simply unzip it to approach the stuffing or cushioning inside.
If you don’t find any zipper on either side, you may have to open the cushion using a thread scissor or cutter.
After that, remove that cushioning from the inside, then refill it. It’s a good idea to take advantage of quilt batting or high-grade polyester fiberfill since they are pretty fluffy and can remain fresh for a long time.
Both options are effortless to find at any local craft shop. Ensure to spread the foam around after inserting it properly. You need to guarantee an entirely even filling spread around it.
If the cushioning inside gets loose, it’s better to use polyester fiberfill since this stuffing material is more straightforward to create a solid shape. Once you finish the filling, simply zip the cushion up, and your sofa is ready to serve.
2. Add a Cardboard Layer or Plywood
Cardboard or plywood provides a firm base to keep the couch cushions from sinking and sagging effectively.
The goal is to find additional supports that you can add to a sagged or sunken sofa but still maintain a good shape.
So, to succeed in fixing a sagging couch with plywood, the first step is to remove the cushion from the chair and measure your sitting area.
After that, cut a plywood piece with the same size as the seating area and use fabric to cover it so that your plywood won’t catch on clothing or cushions.
Place your cushion back over that plywood base, and the sofa should feel a lot firmer now.
Hardware suppliers also offer chair support boards so you can place them under your pads to prevent sagging.
These support bases’ material is often breathable and easy to remove, fold up, and store when not in use.
Based on your sofa’s age and warranty status, you can seek help from both the manufacturer and the retailer or seller where you bought it.
Should you engage with any kind of protection plan or extended warranty, call for help from the company or store first. This act can save you tons of money and time.
3. New Springs
The only way to deal with damaged springs is to buy new ones.
If your couch pads get sunk because of broken springs, the only solvent is to replace them with new springs.
These pad supporters play a vital role in ensuring that the cushion will not sink too overly when someone sits on it.
Therefore, new springs can even do the job more effectively, offering firm support to the pads. They also enhance the chair’s resistance to pressure, shock, and additional weight, hence reducing the chance of sagging.
4. Batting
People usually furnish upholstery, like pillows and quilts, using batting, polyester fiberfill. Surprisingly enough, it also helps make your pads solid again and save you a small budget.
Batting is also straightforward enough to use. All you need to do is simply unzip the cushions and put the batting under the current foam insert. It’ll level out the pad and provide extra support.
Also, batting can maintain its thickness and shape for an extended time, longer than foam inserts. Thus, it’s an ideal option if you want your cushions to remain firm without sagging or sinking on the sectional.
5. Cinching the Cushion
Sew it with buttons to make it stuffier.
Should you wish to make your pad stuffier, you should cinch it with buttons.
First, you will need to detach the stuffing inside as shown in the above section. After that, sew buttons on each side of your pad; we suggest sewing them in the middle area.
Note that your cushion should stay clenched without getting loose by taking advantage of high-grade tensile thread. Please ensure firm, strong cinching between the pads, so it stays in place tightly for an extended time.
When you finish sewing the buttons, simply stuff the pad back in. Now, your sunken couch should recover and serve you well.
6. Add Couch Cushion Lifters or Sagging Couch Support
These couch cushion lifters support a powerful base to the pads and prevent sinking effectively. They’re also rigid enough to carry additional pressure and weight and help with making your posture more comfortable when you sit.
You need an effortless solution that guarantees adequate anti-sagging pad support. Fortunately, some products on the market work perfectly for this purpose.
A standard cushion supporter is rigid enough to tolerate any extra weight. Plus, it can improve your posture when you sit and deter the pad from sagging.
Another beauty is that the user can fold it up quickly for storage if you don’t use it anymore.
There are some pad supports working in the same way as foam inserts. They are easier to use and made from firm, durable materials that won’t sag.
These supports are also foldable, so you can store them easily when you no longer need them.
7. New Foam Inserts
Insert new foams to recover your couch.
The last suggested item to put underneath your chair cushion is new foam inserts. Over time, a long-term foam set naturally loses structural integrity.
Once you notice the sign of that happening, it’s time to reach out to a store and buy new foam.
Most users recommend polyurethane because it’s pretty rigid and can maintain its shape and firmness for a long while.
You can choose to either buy a vast foam piece and cut it off as you see fit with scissors or buy one that bears equal dimensions to your cushions.
Start by getting rid of the current inserts, then slowly insert your new foam insert, gently compressing and squeezing it into shape.
After successfully gaining smooth edges and sharp corners, simply zip up the cushion and place it back to the sectional.
Conclusion
A sofa is usually the focal point of a living room and the most popular decorative furniture. This piece of furniture withstands a lot of use, hence starting to degrade with age.
To ensure a stunning look for your living space, it’s imperative to keep the couch in fresh condition. That’s why you should bear in mind what to put under the couch cushions to add support and keep them from sinking and sagging.
