Which Memory Foam Mattress Topper Is Best?

Memory foam mattress toppers are made up of a layer of memory foam encased in a cotton or polyester cover that sometimes comes quilted.

They can be used to elevate the feel of your mattress, making them either firmer or softer, depending on your requirements. Memory foam has great pressure relieving qualities - the material mould to your unique body shape, providing comfort and support exactly where you need it most.

Here, we’ll talk you through their main benefits, which toppers are best and what you should consider before making a purchase.

Are memory foam mattress toppers any good?

As we’ve said above, memory foam toppers are great additions to your mattress, especially if you prefer sleeping on a foam surface.

Here are some of the benefits of memory foam mattress toppers:

Pressure relief

Memory foam is unique in the way it shapes itself to your body while you sleep. Once moulded to your body, it begins to provide targeted support and pressure relief exactly where you need it most.

If your joints regularly ache after sleep and you think you need extra pressure relief, a memory foam mattress will be beneficial.


You don’t have to use your memory foam mattress topper every night if you don’t want to. You can always take it off in the summer months if you feel like you’re getting a little bit too warm,  then put it back on in the winter.

Specialised comfort

As we’ve explained above, memory foam provides unique support. The same is also true for comfort. 

Comfort is subjective - what feels comfortable to you may not feel comfortable for your partner. But the fantastic thing about memory foam is that you can both experience perfect comfort because it shapes to your body individually.

Money saving

It’s no secret that mattresses are a big investment, with a lifetime of around 7 years. But that doesn’t mean that your mattress can’t start feeling worn and tired sooner.

Memory foam mattress toppers are perfect for adding a new lease of life to your mattress. They can help a mattress feel just like new again - and you only have to spend a fraction of the price.

Are memory foam mattress toppers good for your back?

This entirely depends on the mattress you use with the mattress topper. 

Although memory foam toppers can add extra support to your mattress, they can only improve the feel of the surface they are placed on to a point. So, if your current mattress is too worn, or is the type of mattress that doesn’t provide targeted support for your back, you might want to consider buying a new one.

If back care and support are something that you are looking to prioritise, then we recommend browsing our range of orthopaedic mattresses. These mattresses have been designed specifically for improved lumbar support, providing additional pressure relief for your lower back and hips.

Can you put a topper on a memory foam mattress?

Yes, you can put a topper on a memory foam mattress - and we recommend that you do!

Pairing a memory foam topper with a memory foam mattress creates a comfortable and supportive sleep surface. Whether you buy one with your new mattress or you invest in one later down the line, it’s always a worthwhile purchase.

One of the best reasons to buy a topper is that it can increase the life span of your memory foam mattress. They protect against small spills and stains, and their foam support takes the strain off of your memory foam mattress, potentially adding years to its life. If you want to protect your mattress from major spills and accidents, you can also invest in a mattress protector.

Can I wash a memory foam mattress topper?

It is possible to clean a memory foam mattress topper, and most memory foam mattress toppers have a removable cover that can be taken off and machine washed when necessary. 

Your memory foam mattress topper should arrive with a care guide that contains cleaning instructions. Before following the advice below, please consult your care guide and follow the manufacturer's instructions.

Cleaning a memory foam topper only requires a few cleaning essentials

If your memory foam topper does not have a recommended cleaning method, we recommend trying the following:

  1. Remove the topper from your mattress before cleaning
  2. Vacuum your topper to remove hair and dust
  3. If your mattress has a removable cover, take this off and perform the following steps on the cover (rather than the foam inside of the topper)
  4. Using a mixture of lukewarm water and mild laundry detergent, dab at any stains with a cloth or sponge
  5. Leave your memory foam topper to air dry
  6. Put your topper back on your mattress

Please note: It is important to remember to use as little water as possible when cleaning your memory foam topper. This is because water can break down the memory foam layers inside the topper and affect its look, feel and, potentially its guarantee or warranty.

Memory foam mattress topper FAQs

Here we answer some of the questions our customers often ask before they make their memory foam mattress purchase.

Are memory foam mattress toppers hot?

Memory foam mattress toppers can get warm as they absorb the body heat they use to mould to your body, but they should not get hot. As with every mattress, the warmer you get while you sleep, the warmer your memory foam topper will feel.

Can I use an electric blanket with a memory foam topper?

This depends on both your electric blanket and your memory foam topper manufacturer.

Please consult the care guides that came with your electric blanket and topper. If you cannot find any guidance on this, contact the manufacturer directly.

If you purchased both items from us here at Mattress Online, our Customer Service team would be happy to help!

Can you roll up a memory foam mattress topper?

No, once your memory foam mattress has been unrolled, it cannot be re-rolled.

Rolling up your memory foam mattress topper once it has been unpackaged can severely damage the memory foam inside of the mattress, which may affect its overall look and feel. 

You also risk invalidating your guarantee or warranty.

Under no circumstances should you cut a memory foam mattress topper!

By cutting your memory foam mattress topper, you will invalidate the guarantee or warranty and will ruin the overall quality and feel of your topper.
