Very good quality extra deep fitted sheet.

Yes, I recommend this

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

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!

Great fit

Yes, I recommend this

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

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

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

No, I don't recommend this

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