My mattress is too soft how can i make it more firm?


If you find that your mattress is too soft and you’re not getting the support you need, there are several ways you can make it more firm. Whether you prefer a firmer mattress for better spinal alignment or simply want to extend the life of your current mattress, there are a few methods you can try. In this article, we will explore some effective ways to make your mattress more firm.

Adjusting the Foundation

One of the simplest ways to make your mattress firmer is by adjusting the foundation it sits on. If you have a box spring or slatted foundation, you can try adding a piece of plywood between the mattress and the foundation. This provides a solid base for your mattress, reducing the sinking feeling and increasing the overall firmness.

Another option is to replace your existing foundation with a firmer one. Box springs tend to be softer, so opting for a platform bed or an adjustable base with a firmer surface can make a noticeable difference in the firmness of your mattress.

Using a Mattress Topper

A mattress topper can be a cost-effective solution to make your mattress firmer. Look for a topper made of a denser material, such as memory foam or latex, as these materials provide more support and can help alleviate the softness of your mattress. Place the topper on top of your mattress and secure it with fitted sheets to prevent it from shifting.

Keep in mind that while a mattress topper can add firmness, it may also change the overall feel of your mattress. Experiment with different thicknesses and materials to find the right balance between firmness and comfort.

Using Mattress Firmness Inserts

If you don’t want to invest in a new mattress or topper, you can consider using mattress firmness inserts. These inserts are typically made of foam or rubber and are designed to be placed between the mattress layers to add extra support and firmness. They come in various sizes and thicknesses, allowing you to customize the level of firmness according to your preference.

To use mattress firmness inserts, simply lift the mattress and place the inserts in the areas where you need more support. This method allows you to target specific areas of your mattress that feel too soft, providing a tailored solution to make your mattress firmer.

Rotating and Flipping

If your mattress is double-sided or has a symmetrical design, rotating and flipping it regularly can help maintain its firmness. Over time, mattresses tend to develop body impressions and sagging in certain areas. By rotating and flipping your mattress every few months, you distribute the weight more evenly, preventing excessive softening in specific spots.

Check the manufacturer’s guidelines to ensure that your mattress is designed for flipping. Some mattresses have a specific top and bottom layer, and flipping them may affect their performance and comfort.


If your mattress is too soft, there are several methods you can try to make it more firm. Adjusting the foundation, using a mattress topper, utilizing mattress firmness inserts, and rotating/flipping your mattress are all effective ways to increase the firmness and support of your mattress. Experiment with these methods to find the right solution that suits your preferences and needs.
