If you suffer from a bed that is TOO plush, then you'll need to learn how to make a soft mattress firmer. But exactly how can you do that? It might seem ridiculous, but there are possible ways on how you'll be able to change the firmness of your mattress for better sleep.

Read on as I show you how to make a soft mattress firmer.


Why Make a Soft Mattress Firmer?

Yes, it is possible to suffer from a mattress that's too soft! People complain of a plush bed because of its lack of support. It's very detrimental for those who suffer from back problems, as they need a firmer mattress to help keep their back straight and free from any pain. But, you will want a balance of both sturdy and plush, since having a mattress that's TOO firm may leave you uncomfortable.

I know how it feels to have a mattress that can either be too soft, or too firm. As much as I want to purchase a new one, it's too expensive and takes up a lot of effort. You probably feel the same way as well, which is why I want to share these tips I have learned myself.

How to Make a Soft Mattress Firmer?

You might have to experience sleepless nights or wake up groggy from a painful back. If you fall into the mattress quickly and feel like your back isn't straight or has support, then that's the sign your mattress is too soft and needs a firmer feel for your body.

There are many things you can do to achieve a firmer bed. I recommend that you do most of these methods for better results, and to observe the change for a few days. Here are the things you will need to firm up your mattress:

  • Mattress
  • Bed Frame
  • Plywood Support
  • Mattress Toppers or Pads
  • Room Thermostat

Besides the whole bed or room thermostat, you can buy the support or toppers from any online shop and store near you. Get the reliable support that can hold the mattress, as well as a mattress topper that's firm enough for your body.

Follow these steps to firm up your soft mattress:

Clean Your Mattress


It may be a long shot, but having your mattress professionally cleaned might be able to bring it back to its former glory. If you can't have it taken to a professional cleaner, then leave the mattress under the sun for a few hours, cleaning it right after. Cleaning will help get rid of any bacteria and germs hiding, which may be ruining the quality of your bed.

Adjust the Room Temperature


You might be surprised to know that your mattress softness or firmness is dependent on your room's temperature as well. After you have cleaned your mattress, adjust the thermostat and lower down the temperature. A colder place will help firm up the bed. Changing the temperature works especially for memory foam mattresses, as they tend to get softer when placed in heated areas.

If your room's temperature is cold, but you still suffer from a soft bed, then it may be the things on top of your bed. Avoid using heaters or thick blankets. Don't use heating pads or blankets, especially if you are using a memory foam mattress. Anyway, your body warmth will adjust to the mattress.

Try this method and see if it makes a difference. If not, move on to the next step.

Flip Your Mattress

Just like many other materials, they can get worn out, and you might just need to flip it over for some rest. The other side of your bed may be completely untouched (yet) and still holds the same firmness it did, as compared to its other side. Flipping your mattress will help even out the sides, letting it wear on naturally. Plus, it can help lengthen its lifespan as well.

Take note that this step is not applicable to ALL beds, as some are only one-sided. If you have a double-sided bed, then you can use this method. You might need a bit of help flipping it over, though. If both sides of your mattresses are a bit worn, or you can only use one side, then proceed to the next step.

Add a Mattress Topper


A mattress topper is something you can add on top of your mattress to have a firmer feel. Toppers are a surefire way to have a firmer mattress. Not only is it effective, but it's affordable, and you have a lot of choices as to what type of material you want. You can have a mattress pad made out of a soft yet firm quilt, polyester, or something of more breathable material.

Adding the pad is simple. All you need to do is to lay it on top of the bed and make sure you properly align it with the mattress. Lie down and enjoy its firmness! Just remember to test the mattress pad and have a feel of it, making sure that it provides the enough support.

Add a Plywood Support

Are you still suffering from a soft bed that feels like it falls slightly when you lie down on it? No, it may not be you being overweight, but it might just be the way your bed frame was made. Your bed frame might not offer the enough support for your mattress, thus weighing down a bit. You can add a plywood support on your bed frame and under your mattress.

Not only may this help your bed frame, but it's ideal for mattresses that are soggy or worn out as well if it suffers from an old boxspring that can't take weight the way it used to.

Fix Your Bed Frame


Like mentioned, it might be the problem of your bed frame instead of your mattress! If your mattress is brand new and you still don't have the enough support, then your bed frame might have weak supports or legs. Remove the bed and box spring. Inspect the frame to see if there is any damage. If there is, then it's best to call the seller and ask about any repair. If not, then you can also purchase support bars to see if that will provide the enough support to avoid your mattress from sagging down.

Another option would be to use the mattress on the floor instead of using a box spring, which may help it stay firmer without it from sagging down when lied down on.

And there you have it! Enjoy a better feel for your mattress and end the sleepless or groggy nights.
