How to Make Mattress Firmer: Enhancing Your Bed’s Support

The firmness of your mattress significantly impacts sleep quality and spinal alignment. Over time, mattresses can lose their firmness, but there are several ways to enhance their support. From simple at-home fixes to specific products, this guide will explore how to make your mattress firmer.

Can You Make a Mattress Firmer?

Adjusting the firmness of a mattress is indeed possible and can be done using various methods.

Possibilities of Enhancing Firmness:

  • Environmental Adjustments: Room temperature can affect the firmness of certain mattress materials.
  • Use of Mattress Toppers: A firm mattress topper can add an extra layer of support.
  • Regular Rotation: Regularly rotating the mattress can help in maintaining even wear and firmness.

How to Make a Mattress Firmer

Enhancing the firmness of your mattress can contribute significantly to improved sleep quality and better support for your body.

Methods to Firm Up a Mattress:

  • Plywood Boards: Placing one or two plywood boards between the mattress and the bed frame can provide a solid foundation, thus adding firmness to a sagging mattress. This method is particularly effective for foam mattresses that may lack adequate support from a worn-out box spring or slatted base.

  • Replace Worn Layers: For mattresses with replaceable layers, such as certain latex or modular foam models, replacing compressed or worn-out layers can restore the original firmness. It’s a cost-effective way to rejuvenate a mattress without buying a new one.

  • Adjustable Base: Utilizing an adjustable bed base can also help in making your mattress feel firmer. These bases allow you to change the angle of your mattress, which can improve support and potentially alleviate back pain. Some adjustable bases come with settings that can mechanically firm up the mattress.

  • Flip the Mattress: If your mattress is double-sided, flipping it over can also help. Using the less worn side can provide a firmer sleeping surface. This is especially useful for innerspring mattresses.

By employing these methods, you can effectively increase the firmness of your mattress to suit your comfort needs. This can lead to better sleep posture, reduced back pain, and a more rejuvenating sleep experience. Regularly assessing and adjusting the firmness of your mattress is an important aspect of sleep hygiene and overall well-being.

What Can I Put on My Mattress to Make It Firmer?

Adding specific accessories or making adjustments can significantly firm up your mattress.

Accessories and Adjustments:

  • Firm Mattress Toppers: A high-density memory foam or latex topper can add firmness.
  • Mattress Pads: Firm mattress pads can provide extra support and comfort.
  • Climate Control: Control the room temperature as some materials, like memory foam, are temperature-sensitive.

Incorporating these adjustments, much like how Puffy mattresses are designed for optimal comfort and support, can greatly improve the firmness and overall quality of your mattress.

How to Firm Up a Sagging Mattress

A sagging mattress not only affects comfort but can also lead to back pain.

Solutions for Sagging Mattresses:

  • Mattress Helper: Use a mattress helper or a mattress firming insert under the sagging area.
  • Check the Box Spring: Inspect the box spring or foundation as it might be contributing to the sagging.
  • Topper for Sagging Areas: Strategically place a topper to even out the sagging areas.


Making a mattress firmer is achievable with the right techniques and products. Whether it’s through adding a supportive topper, using plywood boards, or regulating room temperature, these methods can significantly enhance the firmness of your mattress.
