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.

Extar Deep Mattress Protector

Yes, I recommend this

The mattress cover is well sized with very deep sides. The quality of the fabric is excellent, and it is very comfortable to sleep on. However, some of the stitching on the quilting has come undone after only 2 months on the bed, and needs to be restitched.
