Silentnight Airmax Mattress Topper Review


If your mattress is starting to feel a little lacklustre, or the firmness that you once loved about your mattress just isn’t there anymore, you might be considering a mattress topper to extend the mattress’ life.

In this post we take a look at the Silentnight Airmax Mattress Topper, delving into what the company claims it can do and how that might fit your sleep needs.

Silentnight Airmax Mattress Topper Overview

Silentnight’s Airmax mattress toppers have a dual-layer design and hollow polyester and polypropylene fibres. This, together with the mattress’ mesh walls create pockets of air that, Silentnight says, can give you a cooler night’s sleep.

The mattress is billed as being hypoallergenic and machine washable. It features elasticated straps to help it stay put. It has a quilted wave design.

The mattress topper comes in two depths, from standard to extra deep, and is available in the standard sizes Single, Double, King, and Super King.

The Silentnight Airmax Mattress Topper comes with a two-year warranty.

Things to Consider When Buying a New Mattress Topper

So here’s the hard truth: if your mattress is lumpier than a camel’s back, a mattress topper is not going to turn back the clock and make your sleeping experience feel like the first time you slept on your mattress.

Instead, a mattress topper is there to smooth out and rejuvenate a mattress that has a few minor issues, or just to add an extra bit of comfort when you need it.

So, to understand what kind of mattress topper you need and whether the Silentnight Airmax is right for you, have a think about the following:

  • Is breathability important to you?
  • How much extra thickness do you want to add to your mattress?
  • Do you have allergy concerns?
  • Are you looking for an inexpensive topper or want to spend more?


The Airmax Mattress Topper comes with Silentnight’s Airmax technology.

The company claims the topper has hollow fibres and walls made of mesh that will allow air to circulate and so keep you cool throughout the night. If you are someone who really hates feeling hot during the night and loves extra comfort,  this could be a plus.

This topper is unlikely to solve any temperature issues with your existing mattress though, so if your mattress makes you sleep hot already, that problem is unlikely to disappear with a new topper, though it might help a little.

However, if you are looking to swap an old mattress topper for one that is more breathable, the Silentnight Airmax mattress topper is designed to fit your needs, but keep in mind experiences can vary and what is cool for one person might not be for another.

If Thickness Matters, Pay Attention

The Silentnight Airmax mattress topper comes in two different sizes, 300 and 600.

The standard 300 gives you a 3cm deep mattress topper, while the company’s “extra deep” 600 provides a 6cm mattress topper.

You may find listings for a 5cm mattress topper in the Airmax range, however, these seem less common now and the 5cm depth is no longer listed on Silentnight’s website.

If your mattress isn’t fairing too badly and you just want to give it a bit of extra padding or add more comfort without adding layers of material that could make your sleeping experience warmer, then the Airmax 300 might be a good choice.

If however, you want to feel the extra padding, opting for the 600 could give you added comfort while still putting an emphasis on keeping you cool. Be aware though that adding more depth to your mattress topper may increase how much your bed retains heat overall.

There are thicker mattress toppers out there, with some toppers offering 10cm or more in-depth. These may give more padding and extra comfort, but they can also increase heat retention and tend to cost considerably more.

Hypoallergenic Fibres Could Be A Bonus

If you are one of the millions of people who live with a breathing condition like asthma or other allergies, making sure your mattress topper fits your needs is essential.

The Silentnight Airmax claims that it is hypoallergenic. There is no specific meaning for the term hypoallergenic, and companies can use this term without having to adhere to strict standards. It is not the same as the British Allergy Foundation Seal of Approval, for example.

Here, Silentnight is using this term to mean that the Silentnight Airmax 300 and 600 mattress toppers do not contain materials that are likely to cause allergies. In this case, the topper is made of polyester fibres.

For most people, polyester is a lower risk textile but it can give some people an allergic reaction. Common reactions include itching, a rash, and swelling. It is often the dye used in polyester products that leads to a reaction, and not the fibre itself.

As such, people with specific conditions or contact dermatitis may wish to contact the manufacturer directly to find out exactly what is in the topper and whether it is suitable.

For those with general concerns about minimizing allergies, the Silentnight Airmax Mattress Topper’s hypoallergenic fibres are considered low risk by Silentnight and so could meet those needs.

In addition, you can wash the Airmax mattress topper at 40°C. Regular washing can help minimise the build-up of allergens in the fabric and may help to cut exposure to common allergy causes like dust mites.

If you are concerned about allergies, you may wish to instead look at a Silentnight anti-allergy mattress topper or a similar product certified by the British Allergy Foundation.

A Budget-Friendly Mattress Topper

The Silentnight Airmax 300 mattress topper generally retails around £35-£70, depending on the size you need. For the 600, between £88-£140.

When compared to other mattress toppers from similar brands, this makes the Airmax an affordable option for increasing your comfort and keeping cool. The price tells us that the topper is not going to have all the features of some of the more expensive brands, though.

For example, the Airmax comes with a two-year guarantee. Some mattress toppers come with up to eight years or more, but you can pay up to £300 or more for toppers with this extra reassurance.

If an extra-long guarantee isn’t a concern, the Silentnight Airmax Mattress Topper might be a good fit for your needs.

Alternatives To Consider

1. Soak & Sleep Memory Foam Mattress Topper – If you need the extra comfort and support that memory foam can give, Soak and Sleep’s mattress topper is a relatively low-cost option for memory foam support.

2. Silent Night Anti-Allergy Topper – If allergies are a concern, Silent Night’s specifically certified anti-allergy product range might be a better fit.

3. Simba Hybrid Mattress Topper – If you have a bit more money to spend and need something to revive an ailing mattress, this topper comes with its own set of springs to give extra comfort with open cells to help you keep cool through the night.

Final Thoughts

If you want a mattress topper that is inexpensive, will give a layer of extra comfort without adding much heat and can be washed regularly to maintain a clean sleep environment, the Silentnight Airmax Mattress Topper could be a good fit for your needs.
