Key Takeaways:
- A mattress can feel firmer when new, but it typically softens over time.
- There are several ways to make a mattress softer without having to replace it, such as adding a mattress topper, adjusting your bed frame, and more.
- Knowing your mattress's material and firmness level is key to finding the right solution.
What is mattress firmness?
Before we jump into the various ways to soften a firm mattress, let’s clarify what mattress firmness means. Firmness refers to how hard or soft the mattress feels when you lie on it. It’s usually rated on a scale from 1 to 10, with 1 being extremely soft and 10 being very firm.
Firmness is subjective—what feels firm to one person may feel just right to another. Factors like your weight, sleeping position, and comfort preferences all affect how firm a mattress feels. Knowing your mattress’s firmness level will help you decide the best approach to make it softer and more comfortable.
9 Ways to make a firm mattress softer
Here are some practical steps to make your firm mattress softer and more comfortable, so you can enjoy better sleep in no time.
1. Break It In Naturally
If your mattress is brand new, there’s a good chance it’s firmer than it will be in a few weeks or months. Mattresses, like a good pair of shoes, need some time to "break in." The materials will naturally soften with regular use as your body compresses the mattress.
Here are a few tips to speed up the process:
-
Sleep on it consistently: The more you sleep on your mattress, the quicker it will loosen up and mold to your body.
-
Walk on it gently: Yes, it sounds odd, but walking on your mattress (gently) can help soften the surface. Just make sure to avoid walking directly on the edges to prevent damaging the structure.
2. Add a Mattress Topper
One of the quickest and easiest ways to soften a firm mattress is to add a mattress topper. Toppers act as a buffer between you and the mattress, providing extra cushioning. They come in various materials, so you can choose one based on your comfort preferences.
-
Latex Mattress Toppers: Latex is a great option for those seeking softness while still maintaining support. They offer a responsive, springy feel that adjusts to your body without making you feel "stuck."
-
Memory Foam Mattress Toppers: Memory foam is a popular choice for those looking to soften their mattress without sacrificing support. It conforms to your body, relieving pressure points.
-
Down or Feather Mattress Toppers: If you love the idea of sinking into a soft, plush surface, a down or feather topper will give you that “sleeping on a cloud” feeling. However, they don’t offer much support, so they’re best for those who don’t need extra back or neck support.
-
Wool Mattress Toppers: Wool is a fantastic natural option that adds a layer of softness while also helping to regulate temperature. Wool can keep you cool in summer and warm in winter, making it a versatile choice.
3. Rotate or Flip the Mattress
Over time, your mattress can develop body impressions—especially if you sleep in the same spot every night. Rotating or flipping your mattress can even out the wear and create a softer, more comfortable sleeping surface.
-
Rotate: Turn your mattress 180 degrees so the head of the bed is now at the foot. This helps spread out the wear across the mattress.
-
Flip: If you have a double-sided mattress (meaning both sides are designed for sleeping), flip it over to get a fresh, softer surface.
4. Use a Soft Mattress Pad
A mattress pad is thinner than a topper, but it can still make a difference in how soft your mattress feels. Mattress pads are usually less expensive and can provide a subtle, extra layer of cushioning.
-
Quilted Cotton or Wool Mattress Pads: These materials are soft and cozy, and they offer a quick, easy way to improve the comfort level of your mattress. While they won’t turn a hard mattress into a soft one overnight, they can make sleeping more pleasant.
5. Switch Up Your Bedding
Believe it or not, your bedding can impact how firm your mattress feels. Thick, stiff sheets can make a mattress feel even firmer, while soft, lightweight bedding can make it feel more inviting.
-
Choose Softer Fabrics: Opt for sheets made from materials like percale or sateen cotton, linen, or bamboo for a softer, smoother feel.
-
High Thread Count: A higher thread count usually means a softer, more luxurious fabric that can make your mattress feel more plush.
-
Add a Fluffy Comforter: Using a soft, fluffy comforter can create a cozy, cushioned layer between you and your firm mattress.
6. Adjust the Room Temperature
If your mattress is made of memory foam, temperature can actually affect how firm it feels. Memory foam responds to heat, becoming softer in warmer environments and firmer in cooler ones. If your room is on the cool side, the foam may feel stiff and hard.
-
Turn up the heat: Raising the room temperature by a few degrees can soften the foam, making your mattress more comfortable.
-
Heated Blankets: You can also use a heated blanket or mattress pad to warm up the surface directly, especially during the colder months.
7. Check Your Bed’s Foundation
The type of foundation or bed frame your mattress is on can impact its firmness. For example, a mattress placed on a solid, flat surface (like a platform bed or plywood) will feel much firmer than one placed on a more flexible base, like a box spring or slatted frame.
-
Switch to a Box Spring or Slatted Base: Box springs and slatted bases have more give, which can help make your bed feel softer by allowing it to flex more.
8. Add Pillows for Extra Cushioning
If the mattress is firm but only feels uncomfortable in certain areas (like your hips or lower back), strategically placing pillows can help relieve pressure points and make the bed more comfortable.
-
Under Your Knees: If you sleep on your back, placing a small pillow under your knees can help align your spine and reduce pressure, making the mattress feel softer.
-
Between Your Legs: For side sleepers, putting a pillow between your knees can ease pressure on your hips and lower back.
-
Body Pillow: A full-length body pillow can offer additional support and softness for your whole body while side-sleeping.
9. Consider a New Mattress if It's Worn Out
If you’ve tried everything and your mattress is still too firm, it might just be time for a new one—especially if your mattress is more than 8-10 years old. Over time, mattresses lose their cushioning and structural integrity, so no matter what you do, an old mattress may never feel comfortable again.
When shopping for a new mattress, test out various firmness levels and remember that mattresses often feel firmer in the store than they will after a few weeks of use.
How to determine the right firmness level
As we said in the beginning, your ideal firmness level will depend on several factors, including your weight, sleeping position, and personal comfort preferences. Understanding these elements can help you make an informed decision when shopping for a new mattress or adjusting your current one.
Here’s a breakdown of recommended firmness levels based on body weight and sleeping position:
| Weight range |
Under 130 lbs |
Between 130 lbs and 230 lbs |
Over 230 lbs |

Frequently Asked Questions
One of the most straightforward ways to break in a firmer mattress is to simply sleep on it regularly. The pressure of your body will gradually compress the materials, softening the overall feel.
If you want to speed up the process, you can gently walk on the mattress for a few minutes each day or place heavy objects on it to apply extra pressure. Just make sure to avoid the edges, as this can cause uneven wear.
It’s also helpful to rotate the mattress every few weeks to ensure that all areas soften evenly. If you have a memory foam mattress, increasing the room temperature slightly can make the foam more pliable, helping it adjust to your body shape more quickly.
If your mattress is too firm, it can lead to several discomforts and potentially disrupt your sleep quality. A firm mattress may create pressure points, especially if you're a side sleeper, as it doesn’t contour well to the natural curves of your body. This can result in soreness in areas like your shoulders, hips, and lower back.
Over time, sleeping on a mattress that’s too firm may cause stiffness and even lead to long-term pain in your joints or spine, as it fails to offer the right support or cushioning.
For some people, a too-firm mattress can also lead to restless sleep, as you may find yourself tossing and turning in an effort to get comfortable. The lack of proper cushioning can also prevent you from fully relaxing, leaving you feeling less rested in the morning.
Yes, most firm mattresses will soften over time, especially as you continue to use them.
Memory foam mattresses are sensitive to body heat, which helps them soften over time. If your foam bed feels too firm, you can make it softer by warming up the room.
A slightly warmer room can make the foam more pliable, offering better pressure relief and a more comfortable sleeping experience.
Adding a mattress topper can significantly change the feel of your bed. A softer mattress topper can add extra cushioning and make a firm mattress much more comfortable without compromising support.
