How To Make A Memory Foam Mattress Firmer At Home


Improve support

The first and most straightforward way to make your memory foam mattress firmer is to add support. The idea is to add a board underneath the mattress to stabilize it further and keep it from sinking. You are probably familiar with using plywood to fix a sagging mattress, and it’s also applicable for making a soft memory foam firmer. 

Besides plywood, you can use other boards, be it wood or metal, for support. What’s great about this solution is it’s cheap and easy to replace, especially in the long run. You can even target specific areas in the mattress prone to softening, such as those below the shoulders and hips. 

If your mattress uses a box spring, it might also be the culprit why it suddenly feels softer. Over time, the spring loosens and replacing it can help restore the firmness of the foam. And as a bonus, you’ll get a better height on the firm mattress. 


Use a topper

The support underneath the mattress is not the only part that plays a role in making it firmer. Another quick solution is the use of a mattress topper. This will immediately provide you the firmness you want and also prevent the mattress from softening further. 

Because of the many mattress topper options in the market, you should easily find the right one for your mattress. Of course, using it will immediately make the memory foam firmer and even extend your bed’s lifespan. However, please select the right material as this dictates how firm the finish will be. 


Check the room

The final factor that you can manipulate to make your memory foam mattress firmer is the room. Remember that memory foam is highly responsive to temperature. Therefore, it’s prone to softening quickly if the room conditions are warm. 

You can always maintain the ideal firmness by using an air conditioner or any appliance to keep the room cool. You also want to monitor the room temperatures and ensure that it doesn’t get too warm to prevent the mattress from losing firmness quickly. Not only are you keeping the memory foam supportive, but you’ll also feel cool and cozy for sleep.


How to keep your memory foam mattress firm

Now that you know how to make a memory foam mattress firmer, are there practices you can do to keep it firm? You have just read how the room conditions can cause the memory foam softer. But besides maintaining cool temperatures, you can do some direct practices on the foam itself. 

For starters, use covers and protectors for your mattress and ensure that they’re always flat and smooth. These covers will help minimize the daily wear and tear that softens memory foam quickly. They should also help with the pressure the mattress goes through. 

It would be best if you also made it a habit to rotate and flip your mattress. The usage will be well-distributed throughout the material to prevent premature sagging or softening. And finally, always check the care instructions for your bed to avoid memory foam deterioration.
