Good size covers mattress without too much stretching. No shrinkage yet after one wash. Very smooth- I like smooth, cool cotton sheets

Very good quality extra deep fitted sheet.

Lovely quality fitted sheet. It fits the mattress perfectly as I have found many extra deep sheets are not deep enough at the sides to cover my mattress. It feels very nice to sleep on. Colour is a lovely Cream, exactly what I wanted. It washes and drys very well. I would highly recommended M&S sheets. Excellent value in the sale.

Feels cold and rough

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I rarely dislike M&S products but I am very disappointed with this one (along with the matching duvet set). It feels rough and cold to the touch, I thought it might soften after a wash but seems to have gotten worse. Does not feel like cotton, rather a synthetic fabric which always feels cold to touch and has a crunchy sound!

The 31 inch fitted sheet kept popping off in one corner but this one does the job perfectly- lovely and cool to sleep on and feels like quality

Finally fitted sheet that fits a deep mattress (34cm) I’ve struggled recently to find a sheet that tucks in under a deep mattress, this sheet is perfect. Good quality and not too expensive.

Extra deep sheet

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Bought for my son's bed, which has a continental, (slightly larger than a UK), size single mattress. The extra depth means the sheet is big enough to cover and tuck in. Easy care and good value.

Good fit. Creases on washing

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The sheet fits very well but it is quite difficult to iron as it creases so much after the spin wash.

Good but loses softness on washing

Good size, nice colour green, easily fits over quite deep mattress. It was lovely and silky on opening but lost that once washed.
