Comfortable mattress topper that improves sleep quality and softens firm mattresses. Well-made, fits well, and is good value. Some find it thinner or less supportive than expected.

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.

No nightmares. 👍
Bought this as I was put in a hostel (divorce 🤣) and was terrified about a used mattress. 😳 Put this fantastic bit of kit over it and slept like professional kipper. 👍😴

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

Excellent product for price paid
I bought this to add softness and comfort to a double bed I've had for a good few years now. A real bargain with the 20% off. Everything was as described.

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.
