3 Reasons why your couch cushions sag

The couch cushions could be sagging due to the following reasons;

1. The frame is broken

The first thing you should do to find the cause of the sagging is to check whether the couch frame is broken.

If you have a wooden coach, 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 need to fix it by replacing the frame using plywood or cardboard.

2. Uneven distribution of weight around your cushions

You may be fond of sitting on some parts of the sofa while other areas are less often sat on.

This is likely to cause uneven distribution of weight on cushions and with time, they may start sagging. The only way to make the cushions firm again is by getting new foam inserts or fiberfill.

3. Sleeping on the sofa

We’ve all done it. Sleeping on the sofa is a habit that is hard to stop.

This is a bad habit that with time puts stress on the couch springs causing them to deteriorate.

Once the springs become weak, they cannot provide strong support for the cushions, which makes them sag.

Replacing the springs with new ones could be an easy fix if you do not want to purchase another couch.

Make sure the plywood perfectly fits the length and the width of the coach sitting area.

Place the plywood on the couch frame without the cushions. If it sticks too far past the front of the couch, cut it until it fits perfectly.

Since the plywood will be rough on the cut edges, you will need to cover the edges so that they don’t hurt you or snag the cushions.

You can use duct tape or get slipcovers to cover the plywood while protecting the seat from damage.
