Use a Mattress Topper

If your mattress feels too hard, adding a mattress topper is one of the easiest ways to make it more comfortable. Memory foam toppers are great because they contour to your body, easing pressure points and adding softness.  Feather or down toppers create a cozy, plush feel, while latex toppers provide a good balance of softness and support. But who needs a firm mattress in the first place? If you sleep on your back or stomach, a firmer mattress might offer better spinal alignment.

However, if you find your mattress too soft, you can also explore ways to firm up a memory foam mattress by adding a firmer topper or adjusting the bed’s foundation. Aim for a thickness of 2 to 4 inches in your topper for the best comfort upgrade.

Break in the Mattress

If  your mattress feels too firm, it might just need some time to adjust to your body. A new mattress can feel stiff at first, but regular use can help soften it. Try sleeping on it consistently to help the materials break in naturally. You can also walk on it gently to loosen up the fibers and make it more comfortable.

Rotating the mattress every few months can also help even out the wear and soften the surface over time. However, there are reasons why a firm mattress may be hurting your back — if the mattress is too rigid, it might not be providing the right support for your spine, leading to discomfort.

 

That’s why it’s important to give your mattress at least 30 days to break in before deciding if you need to make adjustments or add a topper for extra comfort. Your body needs time to adjust!

Adjust the Room Temperature

Memory foam and latex mattresses can feel firmer in colder temperatures.

  • Keep your bedroom temperature between 68°F to 72°F for a softer feel.
  • Use a heated blanket or mattress pad to warm up the surface and soften the material.

Temperature plays a big role in how a mattress feels, especially with foam materials that tend to harden in cold environments.

Try a Plush Mattress Pad

If a mattress topper feels too thick or pricey, a plush mattress pad can be a great alternative. It adds a soft layer without adding too much height, making your bed more comfortable without feeling bulky. Cotton or microfiber mattress pads are lightweight and breathable, providing a gentle cushion.

Wool mattress pads are another great option since they naturally regulate temperature while adding a cozy layer of softness. Understanding the difference between a firm and a plush mattress can help you decide if a mattress pad is the right solution.

A firm mattress offers more support, which is better for back and stomach sleepers, while a plush mattress provides a softer, more cushioned feel, ideal for side sleepers. Mattress pads are also easier to clean and maintain compared to thick toppers, making them a low-maintenance way to fine-tune your bed’s comfort level without the hassle.

Use Soft Bedding

The right bedding can make a big difference in how your mattress feels without changing its structure. Soft, breathable sheets made from materials like bamboo, cotton, or linen can create a cozy and inviting feel. Adding a down comforter or quilt on top can make your bed feel softer and more luxurious.

Fluffy pillows also help improve overall comfort by providing extra cushioning and support where you need it. If your mattress feels too soft and you’re looking to make a mattress firmer, layering firmer pillows or adding a more structured mattress pad underneath the soft bedding can help strike the right balance.

Soft bedding creates a plush surface, giving you the sensation of sleeping on a cloud — even if the mattress itself remains firm. It’s all about combining softness with the right level of support to get the comfort you need for a restful night’s sleep.

Flip or Rotate the Mattress

A mattress protector is a great way to add an extra layer of support and protection to your bed. It can make a noticeable difference in how firm your mattress feels while also shielding it from moisture, dust, and allergens. Look for a tightly fitted, quilted protector made from high-quality materials like cotton or polyester for the best results.

A good protector not only adds firmness but also helps maintain the mattress’s shape over time. If you find your mattress too firm, you might also want to explore simple ways to make a firm mattress softer. Adding a plush mattress topper or using softer bedding can help balance out the firmness without sacrificing support. A mattress protector is a simple yet effective way to enhance both comfort and longevity, giving you a better night’s sleep while keeping your mattress in top condition for years to come.

Layer with a Blanket Under the Sheets

Adding a soft blanket between your mattress and fitted sheet creates a softer surface.

  • Use a fleece or cotton blanket for extra cushioning.
  • A quilt or comforter can also work well as an added layer of softness.

This trick works well if you want a quick and cost-effective solution to a firm mattress.

Check Your Bed Frame

A firm mattress can feel even harder if it’s on the wrong type of base.

  • Slatted bed frames with wide gaps can make a mattress feel firmer.
  • Try placing a piece of plywood or a mattress board underneath to create a more stable base.
  • If possible, switch to a platform bed or a box spring for better support and softness.

An uneven or unsupportive base can make even a soft mattress feel too hard.

Use a Foam Roll or Pool Noodles Under the Mattress

For a DIY solution, try using foam rolls or pool noodles under the mattress to adjust the firmness.

  • Place them under the mattress to create a slight lift and reduce pressure points.
  • This works especially well for hybrid or innerspring mattresses.

It’s a creative and affordable way to tweak the feel of your mattress without spending much money.

Final Thoughts

Making a firm mattress softer doesn’t have to be expensive or complicated. Small adjustments, like adding a mattress topper, switching to softer bedding, or even adjusting the room temperature, can make a big difference in how comfortable your bed feels. If you’re considering replacing your mattress altogether, it’s important to know where to buy a firm mattress that suits your sleep style and body type.

Many mattress stores and online retailers offer trial periods, so you can test out different firmness levels before committing. But before you go that route, try a few of these simple tricks to adjust the feel of your current mattress. Sometimes, a soft topper or plush bedding is all you need to strike the right balance between softness and support. Finding the perfect comfort level can help you sleep more soundly and wake up feeling refreshed every morning.
