All I can say is it is very comfortable to sleep on. I haven’t tried out the waterproof bit. I hope I never need too.

Great for keeoing stains off your matress

Yes, I recommend this

I've got myself a new matress and wanted to protect it from stains. So i found the perfect thing at M&S, and it was just the right fitting too, plus it was a waterproof cover so all the better.

Excellent product.

Yes, I recommend this

Really pleased with this purchase. I bought based on the previous reviews that said you don't notice the waterproofing when the protector is in use. This is very true, I had to double check the label to ensure I had bought the waterproof one, when felt it's just like a normal protector.

Brilliant waterproof cover and it truly works!

Yes, I recommend this

Great buy when I was panicking what to do to protect the mattress in case of accidents when my husband left hospital a month ago having been a patient for 8 weeks. It washes easily and is definitely fit for purpose. It took a while to dry though but not a concern as it is fit for purpose.
