Check the Sleep Trial Period
If you bought your mattress online, it most likely came with a sleep trial of 100 days to a year, depending on the brand of your mattress. This trial period allows you to see for yourself how the mattress works and feels in the comfort of your home before you fully commit to keeping it long-term. If you are still within the specified trial period, you can get in touch with the mattress company and ask if a firmer version of the mattress is available (if this option is included in the sleep trial policy). If there is no firmer version of the mattress available, you can return the one that you currently have and get a refund as long as the return is made within the trial period. Then, you can proceed to search for a mattress that has the firmness level you prefer.
Use a Mattress Topper
Using a mattress topper is one of the quickest ways to increase the firmness of your sleeping surface. While a mattress topper is regarded as something that is often used to enhance the comfort or softness level of a mattress, the topper can also make the mattress feel more supportive so your body can stay in a properly aligned position while you sleep. To improve the firmness of your mattress, a mattress topper made with either memory foam or latex will do the trick. These mattress toppers are made with dense materials that provide a supportive layer for you to enjoy while you sleep in whichever position you favor throughout the night. A thick mattress topper can also make an old mattress feel comfortable by masking any lumps or soft spots that have formed after many years of use.
Inspect the Box Spring
Box springs will deteriorate over time, especially when the bed is used regularly. Box springs provide your sleeping surface with the firmness it needs to support your body continuously while you sleep and prevent discomfort. When the springs break down, the box springs will not be able to support the mattress the way they once did, causing the mattress to feel extremely soft. If you determine your box spring is damaged, you can opt to buy a new one so you can continue to enjoy a supportive bed. Changing the box spring is a more economical step compared to changing the mattress.
Examine and Replace Damaged Layers
Some mattresses come with layers made with different materials that are all held together by the outer mattress shell or encasement. This type of mattress allows you to remove and replace any layer that has deteriorated so that you can still reap the benefits of the mattress without the need to purchase a brand-new one. Depending on the materials used within the mattress, a worn-out layer may be the reason the mattress became unbearably soft and uncomfortable to use. Replacing the damaged layer can solve the firmness issue and make your mattress feel completely comfortable to use once more.
Fine-Tune the Room Temperature
Some materials that are used in creating mattresses are sensitive to temperature changes. What might feel like a fantastic temperature for your room may be affecting your mattress’ firmness, so you should also check this factor when considering how to make your mattress firmer and more comfortable again. A memory foam mattress tends to become softer when the room is warm and can get firmer in colder rooms. You might want to try bringing the room temperature down a bit to see if that affects the firmness of the mattress.
