How to Make a Memory Foam Mattress Firmer
Is your mattress lacking in firmness? You’re not alone.
Softness, sagging and loss of firmness are common problems that many owners of foam and memory foam mattresses can experience.
If you’re wondering how to make a memory foam mattress firmer, you’ve come to the right place! In this guide, you’ll learn simple and effective ways to improve the firmness of your bed.
How to Make a Foam Mattress Firmer: The Quick Guide
Foam mattresses are coveted for their softness, but too much softness could actually do more harm than good.
Sleeping on a mattress that is too soft can lead to health problems like breathing difficulties, back pain, muscle strain, joint pain, and various health issues related to the misalignment of the spine and hips.
While softness is important to make your mattress comfortable, your mattress should provide enough firmness to ensure your body is well supported as your sleep.
There is even evidence that issues like back pain and mental stress can be reduced by increasing the firmness of your sleeping surface.
Here’s a brief rundown of all the ways to improve your mattress’ firmness that we will cover in this guide:
- place plywood boards (aka bunkie boards) under your mattress to combat sagging
- use sheets that fit your mattress
- flip or rotate your mattress
- check for dampness and dry out your mattress
- replace an old mattress with a new one
- lower the temperature of your bedroom
Add Support With Plywood Boards
Since older foam mattresses don’t have the same structural support that innerspring and modern foam mattresses have, you may need to provide that additional support through alternative means.
Install plywood boards – also known as bunkie boards – under your mattress on top of the bed frame or box springs.
Plywood is thin enough that it won’t be too heavy or drastically change the height of your bed. However, it’s also rigid and solid enough to give your mattress an extra layer of structural support.Any type of plywood will do as long as it’s at least ¾” thick. Hardware stores and lumber yards will often sell plywood by the sheet.
Do Your Sheets Fit Your Mattress?
If you’re working with a tight budget, purchasing a new set of sheets in the right size can be a cost-effective way to regain firmness.
When your sheets are too small, they can tug and pull on the edges of your mattress causing it to lose its flat structure.
Sheets that are too big can allow for pressure loss, and as a result, a lower level of firmness.
Cover your bed in high quality sheets that promote cooling and sit perfectly flat against the surface of your mattress. Pull the edges of the fitted sheet flat to create a taut fit.
Flip or Rotate to Prevent Sagging
Foam is well-known for its ability to take on and absorb any applications of pressure. This includes the weight of your body as you lie down.
While modern foam mattresses have a stronger structure that more easily regains its shape after any applied pressure is removed, flipping or rotating your mattress every few months can help minimize the sagging and lumpiness that can form after several months of enduring the pressure of your body weight in the exact same place.
Flipping or rotating ensures a more even distribution of pressure is achieved.
All mattresses mattresses can be rotated, and some older models are designed to be used on both sides. Check your manufacturer’s instructions before you attempt any flipping.
You Bedroom Could Be Too Warm
Memory foam is a temperature sensitive material as are most polyurethane-based foam materials. In an environment that is too warm or humid, memory foam tends to sink and sag.
In cooler temperatures, memory foam adopts a firmer, more solid structure. Take advantage of this behavior by adjusting the temperature in your bedroom.
Opening windows, turning on a fan, or even lowering the thermostat can make a huge difference in the firmness of your memory foam mattress.
It Could Be Time to Replace Your Mattress
After years of wear and tear, it may be time to replace your outdated mattress for a newer model. Most mattresses should be replaced after 8 years of use.
The latest generation of foam mattresses are much firmer and better able to regain their shape after applications of pressure.
Featuring temperature adaptive technology and pressure-relieving foam layers, today’s foam mattresses are made with materials that have been specially engineered to be supportive and durable.
Check For Dampness and Dry It Out
Earlier, it was mentioned that memory foam is sensitive to temperature extremes. One of the reasons memory foam becomes softer is due to being in a warm, humid environment.
If you’re the kind of person who sleeps hot or if you’re living in a humid climate, you will find the constant exposure to heat and moisture softens the memory foam layers.
To regain the firmness of your mattress, simply remove the excess moisture. One way to do this is to dry out your memory foam mattress.
Strip the mattress bare of sheets and covers and let it air out inside with a fan blowing to promote air circulation. Alternatively, you can set it outside in a covered area to dry on a breezy day that is not hot.
