Great quality !!

Yes, I recommend this

I searched for a long time in various stores and on websites. There was polyester everywhere. Until finally I came across this wonderful product. 100% cotton. I'm delighted. The body breathes during sleep when I sleep on this product. This mattress cover also protects the mattress perfectly

Yes, I recommend this

Great cotton mattress protector, fits bed perfectly, lovely and quilted. Only downside is that it is quite thick and with being cotton takes longer to dry than regular polyester covers. I don't have a tumble dryer.

Cotton luxury

Yes, I recommend this

I bought the mattress cover because it has 5 stars, and it’s exactly that. Perfect size and fit. Lovely to sleep on. It was easy to award 5 stars. It’s 100% cotton so you can’t go wrong.

Good quality

King size, fits well, slightly larger than mattress which should allow for any shrinkage when washed.

Good Quality protector

Yes, I recommend this

Good quality mattress protector but it is too long for our new king size mattress by about 3". Surprised at this as our mattress is a very good quality deep mattress. However, may shrink after washing.

A very nice mattress protector, which was an ideal layer between the mattress topper and the bottom sheet.

NOT 100% COTTON!!! MISDESCRIBED

No, I don't recommend this

Despite all the marketing labels and online advertisement about it being "pure" "100%" cotton, it is evidently, once you open it, wash it and use it, NOT REMOTELY 100% cotton. It contains 5% completely undisclosed fibres, which it appears causes intense itchiness and allergic reactions. M&S refuses to disclose what material it is that they're making you sleep on and breathe in at close quarters for a third of the day. Not a saleable product. Misleading and deceptive conduct and false marketing. Unsafe. M&S do better please.
