Thinking of buying a mattress and want to know how long memory foam mattresses last?
This is the perfect blog for you.
Investing in good sleep is important, and knowing your mattress’s lifespan helps you plan and ensure you’re always getting the best possible rest.
The good news is that a quality memory foam mattress generally has a long lifespan, typically lasting between 7 and 10 years.
But this isn’t set in stone, and a few factors can influence that lifespan.
Let’s take a look at what these are and some tips on how to get the best out of your memory foam mattress for as long as possible.
What is the Life Expectancy of a Memory Foam Mattress?
As mentioned above, you can usually expect a good 7 to 10 years of service from your memory foam mattress.
But this can be heavily influenced by a variety of factors, including mattress quality and usage.
A top-notch, well-cared-for mattress might go a bit beyond the 7-10 year range, while a less robust one might start showing its age a bit sooner.
What Influences the Life Expectancy of a Memory Foam Mattress?
Ever wondered what makes one mattress go the distance while another doesn’t quite keep up?
Here are the main factors that influence the life expectancy of a memory foam mattress.
The Foam Itself (Density and Quality)
This is a big one.
Denser foam usually means a tougher, more durable mattress.
The overall quality of all the materials used in every layer can also contribute to how long it'll keep you comfy.
In fact, a bad memory foam mattress can sometimes last less than 5 years, so it’s really worth investing in a good quality foam.
How You Use It
If your mattress is getting nightly use from two people versus one, or if the kids think it’s a part-time trampoline (we know, it’s tempting!), it might wear a bit quicker.
Your weight can also play a part in how the foam settles over time.
A Bit of TLC (Maintenance and Care)
Taking care of your mattress can make a significant difference.
Simple things like using a protector and giving it the right support can add years to its life.
The Right Support (Bed Base)
Your mattress needs a good foundation.
If its base is saggy or not quite right, your mattress can wear unevenly and won't last as long.
Who Made It? (Manufacturer Quality)
From the fabric on the cover to how it’s all put together, the original craftsmanship is a key ingredient for a long-lasting mattress.
How do you know when a memory foam mattress needs to be replaced?
Nobody wants to say goodbye to a comfy and familiar mattress, but there comes a time when it’s just not doing its job anymore.
Knowing how to tell if a memory foam mattress is bad or simply past its prime is key.
Here are some tell-tale signs that it might be time for an upgrade:
Sagging
Got noticeable dips or body impressions that don’t spring back, especially where you usually sleep?
That’s a classic sign your foam isn’t supporting you like it used to, and it might be time to move on.
(Your back will thank you!)
Lumps and Bumps
If your mattress starts to feel a bit like a lumpy old pillow, it’s probably past its best.
The surface should be smooth and even.
Aches and Pains
Waking up feeling stiff or with new aches, especially in your back or hips?
Your mattress might have lost its supportive touch.
Restless Nights
If you're finding it harder to get comfy or you're tossing and turning more than usual, your mattress could be the sleep thief.
It Just Feels...Old
Sometimes, even without obvious dips, if your mattress is getting on (think 8, 9, 10+ years), it might not be giving you the invisible support and hygiene you need.
Allergens and dust mites can also build up over time.
How Often Should You Get a New Memory Foam Mattress?
This ties back to its life expectancy.
As a rule of thumb, you should look at getting a new memory foam mattress every 7 to 10 years.
Even if it looks okay on the outside, the internal structure that provides support can break down over time.
Listening to your body is also important; if your sleep quality dips or you're waking up sore, it might be time - even if you haven't quite hit that 7-year mark.
Tips for Increasing the Lifespan of Memory Foam
Want to keep your memory foam mattress happy and supportive for as long as possible?
Here are our top tips:
-
Get a Good Mattress Protector: Honestly, this is your mattress’s best friend. It guards against spills, sweat, and all those little things that can shorten its life.
-
Give it a Solid Foundation: Make sure your bed frame is up to the job. Slatted bases with good spacing or a solid platform are great for memory foam.
-
Rotate it (If it’s Designed For It): Many modern mattresses, like our eze™ Hybrids, don't need flipping. But, rotating your mattress head-to-foot every few months can help it wear more evenly – especially if there's a weight difference between sleepers.
-
Keep it Clean: A quick vacuum with an upholstery tool every now and then helps keep dust at bay. If spills happen, deal with them gently and quickly, trying not to soak the foam. Always follow the manufacturer's instructions for cleaning.
-
No Jumping! We know it’s fun, but it’s tough on the foam and the mattress structure.
-
Let it Breathe: When you're changing the sheets, let your mattress air out for a bit. It helps any moisture evaporate and keeps things fresh.
Do Hybrid Mattresses Last Longer Than Memory Foam? (And What About Spring Mattresses?)
| Mattress Type | Average Lifespan | Notes |
| Memory Foam | 7–10 years | Sensitive to density and maintenance |
| Hybrid | 7–10 years | Relies on both foam and spring quality |
| Spring/Innerspring | 5–8 years | Can sag or lose tension sooner |
That’s a question we hear a lot! Hybrid mattresses are a clever mix, combining cosy foam layers (like memory foam) with a supportive spring system.
Think of our eze™ Hybrid Max Mattress or the popular Cooleze™ Hybrid Original Mattress – they give you the best of both worlds.
So, do memory foam mattresses last longer than spring ones, or do hybrids take the crown?
Often, a hybrid's lifespan is pretty similar to a quality memory foam mattress – that trusty 7 to 10-year mark.
What makes a hybrid last is the quality of both its foam and its springs.
Traditional spring mattresses can sometimes have a slightly shorter lifespan, typically in the 5-8 year range. This is because springs can lose their support or become noisy.
However, high-quality spring mattresses can also be very durable.
The advantage of a well-made hybrid is that it aims to combine the durability of good foams with the resilient support of pocket springs.

Got a few more questions buzzing around? We've got you covered:
How long does a memory foam mattress topper last?
A memory foam mattress topper can be a great way to add extra comfort, but it won't last as long as a full mattress.
You can typically expect a good quality topper to last around 3 to 5 years, depending on its thickness, quality, and how much use it gets.
How long does a memory foam pillow last?
Like toppers, memory foam pillows have a shorter lifespan than mattresses.
Generally, you should look to replace your memory foam pillow every 2 to 3 years.
They can lose their supportive qualities and accumulate allergens over time.

Does an Old Mattress Cause Back Pain?
Over time, worn-out memory foam loses its ability to support your spine correctly.
This can lead to poor sleep posture, misalignment, and pressure points, especially around the lower back and hips.
If you're waking up stiff or sore, your mattress might be to blame.
Does Mattress Warranty Length Equal Lifespan?
Not quite.
A 10-year warranty covers manufacturing defects, not general wear and tear.
Even if your mattress is still under warranty, it might need replacing if it no longer supports you properly.
