Reviewers praised the Mattress Protect Cotton Smooth for its excellent fit and quality, describing it as comfortable, breathable, and staying in place without shifting during the night.

I have only had this mattress protector for a couple of weeks and so am unable to comment on its durability but it appears to be well made and fits the bed perfectly. There is slight crackly sensation from the waterproof nature of the cover but this is not noticeable once my usual mattress protector and sheet are placed on top. I like the guarantee that comes with this item and it gives me the confidence that it will keep my mattress in tip top condition.

Don’t know it’s on there..also a considered purchase considering I have bought them for a far less price and the surface of it is the same as the cheaper ones..where the product excelled for me is the fitting of it on the bed.The sides and part that holds to the mattress are a far better fit and quality and stays on the mattress as opposed to sliding up and not staying put..

I bought this mattress cover to provide extra protection to my new mattress. In the past, I've bought cheaper versions which basically didn't fit the mattress properly. Thus cover is a fitted sheet which fits the mattress as it should. It is cotton and washable, and you dont notice it under the bedlinen I'm sure it will last for many years to come.

I bought the mattress protector purely in case I needed to return the mattress, after the 60 day trial. Well, the protector fits well and is comfortable, as you'd expect. As for giving up my mattress after 60 days? They'd have to prise it from my cold, dead fingers!

I wanted a cotton protector for my new mattress and this is just perfect. There are cheaper ones out there but it’s definitely worth spending the extra for the quality. It’s breathable and waterproof, and hopefully will last for a long time.
