About this product
Add a cooler, more supportive layer to your mattress with this topper that brings breathable comfort and pressure relief to your double bed. Made with Airstream Memory fibres that feel springy and responsive, it lets you shift position easily throughout the night. The breathable construction allows air to flow through, reducing heat build-up and keeping you fresher than traditional memory foam. At 4.5cm deep, it adds a generous cushioning layer that gently supports your body. Elasticated corner straps keep it securely in place, so it won't shift or slip while you sleep.
The fitted design makes it quick to add to your bed, and the straps hold it firmly without any fuss. The filling stays plump and supportive, while the cover is machine washable at 40C for easy care. The springy feel means you're free to move around, which supports natural comfort and ease of movement through the night. Whether you're looking to refresh an older mattress or add extra comfort to your bed, this topper delivers breathable support that works hard every night.

Customers Say
Comfortable mattress topper that improves sleep and reduces back pain for many, but some find it too thin, not memory foam, or poorly sized. Mixed durability and quality feedback.

Good quality mattress protector
Pleased with m/protector purchase and have used at home over a hard mattress and this help pad it out for comfort. Also used it at family members house as bed quite soft and therefore the product helped give my back the support I require as have back disc issues. š the mattress protector although not too thick it is perfect for what I require.

Not great
Too thin and doesn't make much difference. I searched for memory foam and it was a bit misleading ads it is jot really that. Quite overpriced for what it is. Unfortunately you cannot return it. Argos delivery is always great though.

Could do with a better zip.
Fits well and works as expected but as the zip is plastic this broke in the first few weeks so the insides keep falling out and needs adjusting every few days.

We bought this to put on a new mattress that turn was too firm. It has made for a much more comfortable sleep. Well worth the money.

Hi Anonymous
This Slumberdown Airstream Memory Fibre Mattress Topper would be slightly bigger in width only. Double sized mattresses are 4ft 6in whereas a small double mattress is 4ft. If you place in the centre there would be a 3in overhang each side.
I hope this helps

Hello Louise,
After checking with our supplier they have advised: This will not make you cold, it's designed to wick away moisture so that you stay cool and dry. The airstream support pad gives the same support as memory foam without the heat build up, again allowing you to stay cool and dry.
Hope this helps.
