3 Reasons why your sofa cushions overeat or sink
The couch cushions could be sagging because of the following reasons;
1. The framework is broken
The first thing you need to do in order to find the origin of the sagging would be to assess if the couch framework is broken.
In case you have a wooden trainer, the board or the frame that supports the cushions can break due to a lot of weight being exerted on it over time.
So, if it’s broken you will need to repair it by replacing the frame using plywood or cardboard.
2. Uneven distribution of weight around your cushions
You might be fond of sitting on several parts of the couch while other areas are less often sat on.
This is likely to cause irregular distribution of weight on cushions and with time, they may start sagging. The only way to generate the cushions firm again is by getting new foam inserts or fiberfill.
3. Sleeping on the couch
We have done it. Sleeping on the couch is a habit that is hard to stop.
This is a bad habit that with time puts pressure on the sofa springs causing them to deteriorate.
When the springs become weak, they cannot offer strong support for the cushions, which makes them sag.
Replacing the springs with fresh ones could be an easy fix if you don’t wish to buy a different couch.

5 Things to place under couch cushions for support and prevent sagging & Sinking
1. Plywood or cardboard
Plywood or cardboard offers a solid furniture base; thereby, preventing the cushions from sagging.
It is a easy DIY method so you don’t have to be professional to do it.

Get the plywood and cut it into a rectangular shape dependent on the dimensions of your couch.
Ensure that the plywood perfectly fits the length and the width of the trainer sitting space.
Place the plywood on the sofa framework without the cushions. If it sticks a lot beyond the front of the sofa, cut it till it matches perfectly.
Considering that the plywood will be rough on the cut edges, you’ll have to cover the edges so they don’t hurt you or snag the cushions.
You may use duct tape or get slipcovers to pay the plywood while protecting the seat from damage.
Put the cushions back to the couch and relax since there’ll be no more sagging.

New foam inserts
If your cushions are sagging, you will need to add new foam inserts to make them firmer because the old ones may have lost their capacity to offer much support.

Compress and squeeze them inside the covers until you get sharp corners and smooth edges so that they inserts can remain place all the time.
