A good night’s sleep is essential for overall well-being, and a key factor in achieving that is having a comfortable and supportive mattress. However, over time, even the highest quality mattresses can lose their effectiveness and begin to affect sleep quality. This raises an important question, how often should you replace your mattress?


Should I replace my 20 year old mattress?

Deciding whether to replace your mattress depends on several factors. After 20 years, it’s likely that your mattress has surpassed its expected lifespan. So if you’re wondering ‘should I replace my 20 year old mattress?’ The answer is most likely yes. When it comes to adjustable beds and their mattresses however, it’s important to replace your mattress every 8 years to receive the best comfort and support possible. While an adjustable bed can provide additional comfort and flexibility in terms of adjusting the position of your bed, the mattress itself plays a vital role in ensuring a comfortable and supportive sleep surface. 

Why replacing your mattress is important

There are many reasons why replacing your mattress is important and those who overlook the negative alterations in their mattress condition will most likely suffer with its undesirable outcomes - such as discomfort and sleeplessness. We list below some other ways in which this could affect you. 

Comfort and support

Over a period of time, mattresses tend to lose their firmness and original shape. You may find that your mattress is either causing discomfort or has started to sag or become lumpy. This could be a sign that it’s time for a replacement as a worn-out mattress will gradually affect quality of sleep and lead to aches and pains in your body. 

Hygiene and allergies

Dust mites, allergens and bodily fluids can accumulate over time on your mattress. Therefore, if you’re experiencing an increase in your allergies, it may be advisable to replace your mattress for better hygiene and a healthier sleep environment.

Sleep quality

A new mattress with the right level of comfort and support can enhance sleep quality and overall well-being. If you’re constantly waking up feeling restless, tired and are experiencing difficulty falling asleep, this is yet another sign that your mattress is no longer serving its purpose. 

Spinal alignment

A mattress that no longer provides adequate support for you can cause improper spinal alignment, leading to back, neck and joint pain. By replacing your mattress with one that matches your body’s needs, can help ease any issues and improve your spinal alignment.


How often should you replace your mattress? The answer to this is that Most mattresses are designed to last around 8-10 years depending on the quality and type of mattress. Thus, a 20 year old mattress is generally considered to have surpassed it’s expected lifespan. 

How to extend the life of your mattress

Taking good care of your mattress and using preventive measures can help extend the lifespan and save you money in the long run. Here are some actionable tips below on how to extend the life of your mattress before it’s in need of replacing. 

Mattress protector

A mattress protector in general will be more affordable to replace than an entire mattress. Consider buying a high-quality protector to protect your mattress against any stains, spills, dust mites and allergens. A mattress protector acts like a barrier, preventing any substances from seeping and causing damage to your mattress. 

Mattress topper

A mattress topper adds an extra layer of comfort and protection to your mattress - minimising any wear and tear whilst providing additional support and extending the life of your mattress. 

Rotate and flip

To prevent excessive sagging and indentations to specific areas, it’s important to regularly rotate and flip your mattress. 


Vacuuming your mattress consistently will remove any dust, dirt and allergens that may accumulate over time. 

Follow guidelines

Following the manufacturers guidelines can help in your search of how to prolong the life of your mattress.
