Good quality mattress cover. It's well padded without being too thick and the light weight makes it easy to handle and to machine wash/dry. Definitely good value for money.

This is the second time I have purchased this particular mattress protector. It's a good thickness without feeling lumpy, and they are very easy to launder. A win all round.

Ordered this because it had a cotton cover, so less slippery and cooler. It’s fine. A good fit and feels nice.

Not very cool

Ok as a mattress cover. Comfortably cool? I don’t feel it’s any different to the standard cover. Certainly not worth the extra money

Love it!

Yes, I recommend this

Since buying a new mattress I have been finding it much too hot in bed. Buying another new mattress wasn’t an option. I bought this mattress protector and it has made a huge difference. My legs don’t get as hot and I am sleeping much better. I was hesitant buying it in case it was a gimmick but I can highly recommend it for reducing heat from the modern foam mattresses.

This really was a waste of money. I’ve had much cheaper ones in the past and they have been fine but this one just crumples up over night. I tried this one thinking it would be better quality but very disappointed.

Does what it says. *IS* comfortably cool. Complete gamechanger with my new mattress which turns out to be uncomfortably warm for a menopausal woman

Great quality

Originally posted on marksandspencer.com (UK)

Quality mattress cover which fits my bed well . It is nicely padded with the quilting which feels very comfortable under the sheet. The cotton material feels cool so good for the warmer months. Mind you with this very poor summer, particularly up here in Scotland, it was actually too cool some of the time and I had to change to a warmer protector! Sure it will be well used in more normal summers though. Washed well too. Would recommend this one.
