Sofa—your favorite place in the living room

Couches and sofas are our beloved spots in the house—admit it!

We love hanging out with our families and friends on the couch. 

We can’t wait to spend lazy Sundays or busy Friday evenings among cozy pillows, chips, bottles of wine, and inside jokes. 

Where does it all take such an excellent shape if not on a couch?

However, using this most exploited piece of furniture comes with a couple of burning questions. 

First off, there’s a purchase stage. 

You pick an expensive, luxury sofa to place in the center of the living room. You know that the right sofa has the power to establish the atmosphere of the room. 

Your guests love it! 

Yet, cushions are like people—they get old. 

After some time, as you continue being super comfortable on your couch, dents begin to show on the cushions. 

The embarrassment that they cause you in front of others is one thing. 

Sitting on these couches could start to be complicated—this issue from the practical point of view is even more problematic. 

It’s hard to maintain posture when you are sinking all the way in.

With time, cushions start sinking. That’s just how it is. 

It’s essential to take action when you notice it instead of sinking into despair. 

Is there a way to prevent the wear and tear of a couch, or more specifically, to prevent couch cushions from losing their shape? 

You could use a few handy tips to learn how to prevent your couch from sagging, don’t you?

Correcting the problem of sagging cushions can not only improve your posture—it will also improve the returns that you get on your furniture investment.

Let’s give it a shot!

Why are cushions sinking in the sofas?

Couches are durable in their nature. 

They can put up with:

  • stains, 
  • spills,
  • children, 
  • pets, and 
  • naps;

So why is a sagging sofa such a common problem? 

Let’s find out why couch cushions start sinking before discovering how to repair this issue using DIY methods.

For starters—you sit or lie down in the same spot on your sofa for several years. 

How could couch cushions not begin to alter their form?

The foam in your sofa cushions will inevitably sag at one point, simply because you use it so often.

What are the most common reasons behind a cushion sinking?

Sleeping on the sofa

As we mentioned above, using your sofa excessively is not the best idea for both of you. 

Important: This piece of furniture is uneven and usually shorter than a traditional bed. It makes it an unhealthy place to sleep. 

The biggest issue that your couch will face is the weight pressure on the springs. 

When you sleep on your couch too much, its springs will deteriorate and lose elasticity—and deteriorated springs won’t keep sofa cushions firm and in place. 

Broken frame

The second reason that could cause the sagging of your sofa is a broken frame. 

If this nasty sag is concentrated on a specific spot, it may be helpful to examine whether the wooden frame isn’t broken. 

In this case, the whole sofa doesn’t have to end up in the trash! 

It’s just a matter of a quick repair to fix the whole problem. 

Uneven weight distribution

When you pick your favorite spot on a couch, you usually do it for a reason:

  • it may be where it’s most comfortable to watch TV, or
  • where sitting with your laptop is the most convenient;

This habit is excellent for you, but not so much for your sofa. 

Spending too much time in one place means it will show signs of wear and tear earlier than in other places. 

It also means that this particular place will sooner show a dent and begin to sag.

How to bring our sofa cushions to their ideal shape?

Fluff your cushions by hand

Here’s one easy way to revamp your living room seating.

Fluffing your cushions with hands is just as simple as it sounds. 

Keep your couch cushions from sagging by taking them in your hands and fluffing; 

Tip: You can do it with your foot if you wish; it doesn’t have to be done with your hands. Play with your kids inventing the best way to fluff your cushions!

Here’s how to do it:

First, place your couch cushion on a clean surface.

Then, punch the cushion thoroughly on one side—or stomp on it in clean socks if you feel like it. 

Flip it over and repeat the process. 

Do this for each sofa cushion.

It will ensure the fuller and fluffier look of your beloved couch.

Add polyester fiberfill to your sofa cushions

If you tried with fluff, but it wasn’t sufficient, consider the following method. 

Add extra padding to turn your cushions into fresh-looking ones.

Polyester fiberfill is an affordable way to provide some extra volume to worn-out cushions.

It only sounds sophisticated. Stuffing your sofa with a fiberfill to undo your sagging sofa is actually a popular method, and this material is widely available at any craft store. 

You’ll do best to make use of a high-quality polyester fiberfill or quilt batting—they are both quite fluffy in nature, and they will maintain their own. 

Also, both options are readily available at any craft store.

How to refill your cushions with a DIY method?

First, unzip your cushion cover. 

Cut a piece (just a thin strip) in the inner lining that covers the padding.

Feel around for any empty spaces within the padding.

Now, take a piece of fiberfill and begin filling in any holes you find. 

Tip: Keep the fiberfill fluffy and not compacted when you insert it into a pillow.

When the fullness of your cushion seems sufficient:

  • sew the inner lining back together, and 
  • zip up the cover;

Make sure that after inserting the foam, you spread it around correctly.

Tip: You want to ensure that the entire filling is spread around evenly. Otherwise, you’d have to buy a new polyester fiberfill over and over.

Repeat stuffing for all remaining cushions. 

It requires a little cost to purchase and even less effort to make your sofa look new!

Add a plywood layer

Sometimes, the issue that you’re facing with your sofa cushions is structural.

It means that you need to do more than replace missing polyester fiberfill filling. 

A piece of plywood support needs to be placed under the sofa cushions.

Plywood is designed to provide more significant support and prevent further structural problems that your sagging couch goes through.

If you can’t find a piece of plywood made especially for a “sofa emergency,” DIY cut a piece of plywood and use it instead. 

Plywood is readily available at any carpenter or joinery store.

Repair the jute webbing

Another solution to the problem of a sagging couch is a minor repair. 

If you have a web of jute underneath the cushions, determine if it needs to be repaired. 

Important: We find Jute webbing in the suspension systems within the furniture. It’s made up of a natural vegetable fiber spun into very strong bands.

It may be the case that your jute supports must undergo adequate repairs. 

When it’s done, it will bring the cushions back to their firmness while placed on the sofa. 

Simply put—if the webbing is loose, the cushions are going to sink into the sofa.
