Slumberdown Airstream Topper Review

The Slumberdown Airstream is perfect if you want a cooler mattress topper that’ll soften up a mattress but still has plenty of support.

It’s designed with, you guessed it, Airstream technology, this provides little air pockets that allow air to flow through the whole thing.

A great alternative to memory foam this topper is filled with a polyester filling, so quite likely to be similar to your pillow, just a lot more stuffed!

If you’re looking for a really soft topper than this won’t be quite right, but if you’re looking for something a little softer with good support but you don’t want memory foam then this is the topper for you.

The cover is quite soft, a microfibre material, so it’s quiet under your sheet and there are the all-important elastic straps to keep it to your bed.

A mattress topper is the perfect way to:

  • Soften up a hard mattress
  • Add extra support
  • Protect and extend the life of a mattress
  • Get rid of the feeling of lumps

Original Product Description

Amazingly comfy and cooler than memory foam, the Airstream topper will revolutionise your mattress comfort. The topper is a whopping 4.5 cm thick so it’s deep enough to support your contours keeping your spine nice and straight.

What’s more, it’s proven to be significantly cooler than memory foam thanks to Slumberdown’s clever Airstream technology. So you’ll stay cool and comfy all night long.

Plus it’s made in the UK.


Slumberdown Airstream Topper Review

Brand: Slumberdown

Filling: Polyester

Firmness: Medium

  • Breathable
  • Cooling
  • Supportive
  • Hypoallergenic



The Slumberdown Airstream comes with excellent big long elasticated corner straps. It’s such an important detail that can really make or break the entire topper. So I really appreciate Slumberdown’s attention to detail here.


The inner is made from breathable polyester fiber. It gives a feeling which is somewhat similar to down; yet as a synthetic equivalent. In the packaging it feels somewhat similar to a dense duvet, but it feels like a soft, refreshing, cloud to lie on.

It provides a really noticeable difference in airflow. Particularly in cases where your mattress could do with a bit more breathability. You won’t get that with most memory foam toppers.

I am really surprised at the bonus support it provides while having the potential to really soften up a firm mattress. At 4.5cm thick, it adds a lovely layer of comfort to soften up any mattress.


The supersoft microfibre cover feels lovely against the skin. I would say it’s a shame to cover it over with a mattress sheet, but using your favorite sheet only makes it better. A bed truly is more than the sum of its parts.

The cover is removable and machine washable which really guarantees this topper can always provide the freshness along with the coolness it promises.

A removable cover is a must-have in my books. I love a crisp, fresh, clean bed.

Airstream Technology

The Slumberdown Airstream Topper is built with, you guessed it, Airstream technology. This is a build of clever breathable fibers that prevent the build up of heat and allows moisture to escape. It is significantly cooler than regular memory foam mattress toppers.

It brings a breath of fresh air to any bed. Ideal if you’re a “hot sleeper”.

This superb breathability and temperature regulation make it an ideal choice for your little one. Babies and young children are not fully able to manage their body heat as effectively as an adult. The Sulmberdown Airstream Topper is designed with preventing overheating as a priority.


The Slumberdown Airstream topper is non-allergenic. Perfect for allergy sufferers.

If you suffer from hay fever, eczema, or react to dust mites then this topper will help to keep your allergies in check.

The Airstream Memory Fibre Variant

The Airstream Memory Fibre variant has a slightly different filling from the regular airstream. This option uses memory fibers. Similar to memory foam, these are springy fibers which want to spring back into their original shape when you’re not lying on them.

It is more supportive and provides pressure relief, like memory foam, but super breathable like the regular airstream. The memory fibers will mould and contour to your body shape. It’s the best of both worlds.

What Sizes Are Available?

It comes in three sizes, fitting singles, double beds, and king sizes.

  • Single: 90 x 190 cm
  • Double: 135 x 190 cm
  • King: 150 x 200 cm.

It’s 4.5 cm thick so not hugely thick but definitely perfect for propping up and old mattress or if you’re looking for a mattress protector that has a bit of extra comfort.


If you are a “hot sleeper” then breathability is a must for your bedding. The Slumberdown Airstream Topper does an excellent job of letting that needed fresh air in under you, and unwanted heat and moisture out.

The non-allergenic build and washable cover amount to a fresh bed that feels great and doesn’t upset your skin or any allergies.

With allergens and overheating solved, you’re in for a good night’s sleep.

If you’re considering a new mattress, pairing it with the Slumberdown Airstream Topper will prolong the life of that mattress, bring an extra boost of comfort, and guarantee a better night of rest.

Don’t just take my word for it. Check out the brilliant customer reviews it has received over at Amazon. Most locations in the United Kingdom are even able to get next day free delivery.
