Comfortable and great value for money.
I’m genuinely flabbergasted at the quality of this mattress cover considering its selling price. I was expecting less of a quality item if I’m honest. Instead it’s absolutely perfect, it’s extremely comfortable and if left for about 3-4 days to give it a chance to “fluff up” before sleeping on it it is definitely a good deep mattress cover. Will be purchasing for all my beds.

10cm of cloud softness
I don’t know what unit of measurement those ppl are using on here when they complain it’s not 10cm. It’s exactly 10cm. Honestly, some ppl just like to moan! Anyway- great topper. Hotel style - evened out our mattress and is incredibly comfy. I got it because I’m developing a bad back, neck, hip etc and this really feels like it’s helping.

Not 10cms thick. But still lovely!
Blissfully comfortable and makes such a difference when put on top of my old mattress. I’m very happy with it but it’s nothing near the 10cm thickness claimed in the listing; it’s more like 5cms. Still a great buy though!

Ok for the price.
Don’t be fooled by the pictures. The topper is nowhere near as fluffy and high as the picture would make you believe. It’s ok for the price but if you are after something truly fluffy look for something else.
