How To Choose The Best Couch Support Slats And Inserts

1. Material Of The Support

As we have seen in our reviews above, most couch cushion supports are made of particleboard, wood, or fiberboard. Others use foam, which might not be as strong as wood or particleboard.

The material used also determines the stability or rigidity of the support. So when choosing the inserts, pick the one that feels firm and offers maximum support when the seat is sat on.

2. Extent of The Support You Need

It is important to consider the extent of the sagging before picking the type of support insert you need.

This is because couch supports will not prevent your couch from sagging if the cause is broken springs. In this case, you might have to replace the springs.

The supports work best if the frame of the seat is broken or the cushions have lost their firmness. The supports are strong enough to provide additional support without having to replace the broken frame.

3. Size Of The Cushion Supports

Cushion supports and slats come in different sizes so have to fit different seats such as loveseats, sofas, recliners, chairs, and couches.

In order to cater to the different seat sizes, the supports are foldable. So you can adjust them to fit different seats in your house.

Nonetheless, you are strongly encouraged to measure the length and width of seats under the cushions so as to choose the right size.

You don’t want to buy one that extends past the cushions since it will be visible and will make the seats very uncomfortable to seat on due to being pricked on the legs.

1. How to replace couch cushions?

The first step is to know which cushion foam works the best for you. You should pick durable ones that live longer, so you can choose either memory foam or polyurethane foam. The next step is to measure the cushion, so it is easy to determine the size of the filling you need. 

2. Why do cushions sag?

Cushions come with a softer filling which can compress over time. This causes them to sag. Improper weight balance can also throw them off. Cushions typically also sag if the serpentine springs within the couch frame are loose. They have to be reattached and secured to prevent them from loosening again. Sometimes, you must replace the springs if they are broken from their attachments.  

3. How to prevent the cushion from sinking?

The simplest way is to fluff the cushions so they do not sag often. Remember to flip them regularly as well. Another way to lessen the sagging effect is to wash your cushion covers so that their shape is retained. Investing in good quality furniture is also helpful since sagging can be caused by the couch too.
