About this product
Refresh your mattress and enjoy breathable, allergen-free comfort with this mattress topper that's designed to keep you cosy all year round. It's deeply filled with hollowfibre and features air mesh sides that let air move freely between the layers, so you'll stay comfortable in every season without overheating. The dual construction helps to protect against bacteria and dust mites, which makes it a great choice if you're prone to allergies. It fits king size beds and adds a soft, supportive layer that helps extend the life of your mattress while providing 5cm of extra cushioning.
The elasticated corner straps secure it firmly to your mattress without shifting overnight. It's machine washable at 40C and tumble dryer safe, so maintenance is simple and convenient. The durable fabric keeps its shape beautifully and stays plump after use, while the anti-allergy treatment helps keep allergens at bay. Whether you're improving your own sleep space or updating a guest bedroom, this topper provides comfort and protection you can rely on.

Customers Say
Comfortable mattress topper that improves sleep and softens firm mattresses, but often thinner than advertised and may flatten under pressure. Good value but not very supportive or firm.

It's an improvement
Had this about 3 weeks and yes there is definitely an improvement and I am definitely sleeping better. Sometimes I think should I have just bought another duvet and used that because when you look at it it's not very thick really and there doesn't seem to be that much difference than when I slept on top of the bed during the heatwave but I'm no expert so all I can say is that it better than it was before and perhaps I should have got the 8cm one instead of the 5cm one. It is technically 5cm, but when you lie on it it and the air escapes, it's really like 2cm to be honest. My advice to anyone is when you are buying a mattress in the first instance is to factor in the possibility of having to take these measures and buy one more expensive than the one you were looking at. I bought a silent night firm mattress and it's like concrete. I should have paid more. In conclusion this is better than nothing.

Just a Duvet
I dont normally like to leave bad reviews, but ! This is advertised as being 5cm thick, its isn't. Its basically two duvets put together with absolutely nothing in-between. I left it overnight to see if it inflated any further, it didn't. The minute you put any pressure on it, it goes flat.

Not a temperature regulation mattress topper.
Mattress topper doesn’t do anything in relation to temperature regulation, it’s soft but not impressed with it.

Check sizing before you buy!
This is a really nice mattress topper, but it is too small. It is NOT a king size - it is too short and too narrow, which is a shame, it just leaves a big edge all round the mattress which looks ill-fitting and a bit cheap to be honest.

Excellent
My new silentnight topper is great, so comfortable.

Transforms an unforgiving mattress
Only bought this recently, so have used it for just two nights – but in some of the hottest weather! It definitely has transformed a rather unforgiving mattress and has proved comfortable, not finding it hot at all. It's well made and finished with a useful bag it came in for other bedlinen storage. The 5cm depth is a bit of a ruse, as it is but don't go away with the impression you actually get 5cm depth as it flattens out. It still feels great though.
