About this product
Give your mattress a supportive refresh with this memory foam topper that moulds to your body and relieves pressure on joints and spine. It revives older mattresses with a soft microfibre cover treated to fend off dustmites and bacteria, so allergy sufferers can sleep peacefully. The memory foam responds to your weight and warmth, creating personalised support to help you wake rested. Fitted with an elasticated skirt, it grips your mattress securely, staying put all night without shifting or bunching.
The cover unzips easily and is machine washable, so you can keep it fresh and clean with minimal fuss. It's tumble dryer safe too, which makes care straightforward when you're busy. The slip-resistant backing keeps everything in place, even if you move around during sleep.

Good
Happy I purchased this last month, deffo helped with my aches and pains

Decent topper
Easy to put on a mattress and remove it's cover for washing. Replacing the cover is a little fiddly but fine. The topper provides a decent amount of support but not a lot. That's the trade-off for it's portability I suppose!

Not good to lay on.
Been trying to sleep on this but overnight ruffles up making hard lines in middle of bed.

Cheap. But not worth the money!
The ad said that it was 40 mm thick but not that it was of uniform thickness. It is actually less than 40 mm and the effective density is less because it is of"egg box" construction, although with one smooth side.. The accompanying text indicated that it was attached to the mattress like a fitted sheet; whereas it had loops on the corners. (Actually the picture showed that it had loops at the corners but as the adjacent pictures looked identical it didn't appear representative. The text should not have been misleading.) I couldn't be bothered to return the item as it was hardly worth the fuel to take it back. I would not recommend this item to anyone looking for a memory foam topper.

Very comfortable! Ideal.
I bought in the sale, so very good value for money. I followed the clear instructions for airing and putting on the bed. I'm delighted to say it is exactly what I was looking for and I now sleep very well indeed!

Very Thin
I’m sorry to say that this product is not brilliant. I suppose it depends on what you want or expect it to do, but in terms of adding extra padding for painful joints it doesn’t do the job. It isn’t solid memory foam, just very thin, shaped stuff- that kind of foam that consists of points and troughs for want of a better description. On an uncomfortable mattress it was better than nothing, but only just.

Not impressed
Bought this at half price and its ok given it was cheap. Got it on top of a very hard mattress and it’s hard to tell how much of a difference it really makes. The foam is about 2.5cm thick so don’t expect a huge improvement in comfort. It comes in a cover that’s far too big for the foam and therefore goes quite wrinkly. So I just removed to cover and am holding it in place with a different mattress topper. Fine for half price but would not have bought this for the full sum.
