A sagging couch ruins the look and comfort of your living room. To give a new life to your couch, you need the best couch cushion support.

A couch can sag due to different reasons. But the most common one among them is the cushions being worn out. So what to do in such a scenario? Do you change the entire sofa?

Luckily, the answer is no. Cushion supports are an easy and inexpensive fix for your sagging cushions. They not only improve the current shape of your cushion but also strengthen them and increase its durability.

Here, read all that you need to know about cushion supports along with the details of some top picks of couch cushion support.

What is the Best Thing to Put Under Couch Cushions?

Couches are not only some pieces of furniture. Rather, they are our comforting places. We relax on them, watch movies lying on them and sometimes even sleep on them; because who can resist the comfort, right?

But when the cushion sinks, the couch becomes uncomfortable to even sit on. People sometimes throw out fine couches simply because the cushion has worn out; because they don’t know any other options.

To start, let’s know the reasons why cushions sink. There are a number of causes behind this. Such as the frame being broken, some parts of the couch being more frequently sat on than other parts of the couch, the springs not working, etc.

When these are the culprits behind your sagging sofa, there are pretty inexpensive things to put under couch cushions to make them firm again. Below are some options for fixing your sagging cushion.

Cardboards and plywoods

A couch support board can serve as the base of your couch. They fix your problems with broken frames or sagging cushions.

Cardboards or plywoods provide your couch with strength and support, making it durable. It is also a cheap option. You don’t need any skills for this DIY project.

Start by buying large cardboard. The stronger the better. Use any cutting tool that allows you to cut the cardboard precisely.

Measure the length and width of your cushion for the precise sizing of the cardboard. Then carefully mark some points on your cardboard for cutting directions.

Make some smooth cuts on your cardboard to give the size of your cushion. Now place the cardboard under the cushion to see if it fits perfectly. If it doesn’t, cut it again and again until the right size is achieved.

Before using them under the cushions, cover the edges of the cardboard with duct tape or slipcovers to prevent them from ripping the cushions.

New foam Insert

One of the biggest reasons behind couch cushions sagging is the foams being shabby. Foams are not so durable materials, and when the couch is often used for sleeping or the weight is unevenly distributed on different parts of the couch, the foams sag.

But there’s nothing to worry about; foams are also cheap enough to change once in a while. They are incredibly easy to get, but you should try to find some better quality foams for more comfort.

Once you get some food foams, unzip the cushion covers and bring the old foams out of them. Then insert the new ones into the cover and you’re done!


Polyester fiberfill or batting is a much more durable option compared to foams. They can be used on cushions and pillows.

Insert them into your cushion covers just like you would do with foams.

Under Cushion supports

Not everyone has either the time or energy for DIY projects. If you’re one of them, you can get some ready-made cushion supports for a quite reasonable price.

Things to Know Before Buying Cushion Support for Couch

There are several things to consider before buying cushion supports. Below are listed the important factors that you need to keep in mind.

Damage Type:

As previously mentioned, there are different factors behind the sagging of your couches. The repairing process also varies according to the cause. But almost all the problems are easy to fix.

When the frame gets broken, you need to use some cardboards or plywoods to complete the structure of your couch. So before ordering any repairing tools, you should first check the frames.

If the frame is alright but the foams are sagging, then get new foams or substitutes for foams. But remember, the quality of foams will make much difference to the comfort of your couch.

Lastly, if the springs are not working properly, get new springs. The installation process of springs may require special tools and skills, but it is still far inexpensive than getting new couches.


The size of cushion supports must fit the size of your cushions. It doesn’t matter whether you put the supports under your cushions or inside them, if they are visible from the outside, then it will ruin the elegance of your couch.

That is why measure your couch and cushions before ordering any supports. If you’re not sure about the size of the supports, get customizable ones. You can easily cut them and make them fit perfectly into your cushions.


Everyone doesn’t prefer to sit on the same kind of surface. Some like their couches to be a bit rigid, others want them to be soft. The rigidness or softness of your couch depends on the materials of the inserts. So, it is up to you what kind of inserts you will choose for your couch.

Usually, foams are much softer than batting. So if you want a softer surface, buy foams. The quality of foams also varies and impacts the overall comfort of your sofa. But batting is more durable than foams and they last longer.

FAQ’s About Sagging Sofa Cushion Support

Why should I get cushion supports?

Cushion supports are helpful to both new and old couches. If you have an old couch that has started to sag, cushion supports can make them firmer again and protect them from further damages.

What to put under sofa cushions for extra support? 

There are many cheap and widely available options that you can put under sofa cushions. Use cardboards, plywoods, or any lightweight wooden boards of this kind to support the overall structure of your couch.

How do I fix the worn-out springs of my couch? 

There are special tools and skills required to fix deteriorated springs. Usually, fixing them isn’t enough to make your couch comfortable again. So you should consider getting new springs for your couch.

How can I prevent my couch cushions from sagging? 

To prevent the couch cushions from sagging, provide them with extra support such as putting cardboards or plywoods under them. Also, use good-quality foams or batting inside the cushion covers.

There are also a few things that you can do to elongate the life of your couch. Do not sleep on the couch! Sit on different parts of the couch after every while to ensure even load on different parts of it. Following these, you will increase the strength of your couch.

 Final Words
