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.

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.

Dosapointed Not 5cm thick all over.
I was rather dissapointed with the thickness of the topper. Althought it says 5cm it is quite flat, certainly not 5cm. Just because the fabric at the side measures 5cm the topper does not sit 5cm high and not as comfy as I hoped. It made some difference

Very good for price
Have been using for 2 weeks. Is very good quality and makes mattress a lot softer Was brought for husband post hip replacement operation. Only given 4 stars as does make it a bit warmer. So is fine for winter/colder nights but may be too warm for summer.

Disappointed
I’m fairly disappointed with this mattress topper. The advert stated that it was 5cm thick; however, that only seems to be the case if you pull it apart, as there isn’t enough filling to properly support its shape. Once you sit or lie on it, it becomes completely flat. For the price, I think it’s overpriced and doesn’t offer good value for money.

Mattress topper silent night
Disappointed it wasn’t more firm
Disappointed
Not what I expected
I thought by looking at the photos this topper had a deep edge and was thick, possibly foam filled. I read the reviews which were great. So l bought it. I don’t think it was going to be any better than putting a spare duvet folded over on the mattress so l returned it without trying it. I had a look in the bag and realised my mistake. I ordered what l should have ordered. A 2” foam topper for which I’m very happy with.

Hi, Chris
I can advise that the Silentnight Airmax 5cm Mattress Topper - Kingsize is placed on top of an existing mattress and held in place by the mattress protector and/or sheet.
Thanks for using Q&A.
