Good fit

Yes, I recommend this

With M&S brand you know it will do the job and fit. The extra deep mattress does mean it is a struggle to fit if a cheaper brand is purchased as they can be a bit mean.

Ideal for a very deep mattress

Yes, I recommend this

Wanted an extra deep mattress cover with a cotton skirt. Find that the polyester lose their elasticity. It was very loose at first but after a wash it now fits perfectly.

100% cotton

Yes, I recommend this

I chose this mattress protector as it was the only one with a 100% cotton skirt, previous proctectors with polyester skirts have lost their elasticity to fit and overall appearance after just a few washes.

Badly sized

No, I don't recommend this

Badly sized-too large and therefore no 'grip' on mattress base
