Nice and comfy

Yes, I recommend this

Been looking for a small double mattress protector for a while so was pleased that M&S had them. Fits like a glove. No more moving around with a standard double size.

Very pleased. Good value.

Yes, I recommend this

Very pleased with this. The stretchy 'skirt' means that it fits the mattress properly - so much better than those with just elastic straps at each corner. Nice soft feeling quilted protector. Good value.

My mattress is happy!

Yes, I recommend this

My new mattress cover is deep fit and the 4corners have elastic to hold mattress in place. It stays that way so it’s a smoother sleep. I actually feel I am sleeping better.
