Does the job

It does the job but it crinkles like paper, I suppose that's the cooling part of the sheet 🤔

Fabulous bedding, so soft and luxurious. I’ve bought the full set of this bedding, it’s incredibly comfortable and so cool in this hot weather. It’s been an add bonus that I’ve managed to buy most of the sheets in the 50% sale so an absolute steal. Very happy customer.

Ordered the Cotton bedding in Sage Green. Bedding seems very thin & feels cold. Hope when it is washed it will feel softer & warm.

Beautiful flat sheet

Originally posted on marksandspencer.mom (UK)

I find it much easier to put a flat sheet on a bed than a fitted. These are lovely and feel nice against my skin. Grabbed a bargain, so very happy.

Decent size flat sheet

The cotton does feel a little bit hard on touch. Washes well has a tendancy to crease easily.

Peculiar texture and feel

Originally posted on marksandspencer.mom (UK)

No, I don't recommend this

Like other reviewers have noted, these have a very peculiar feeling to them, not like any other cotton bedding I have from M&S in the past. Very disappointed.

Great value

Originally posted on marksandspencer.mom (UK)

No, I don't recommend this

I thought these sheets would feel thin as they were such good value but was nicely surprised with the quality. I will have to try different ways of washing and drying as they were difficult to iron after 1st wash and light tumble dry hence dropping 1 star. Will wait for a few more washes to see if I can improve it before purchasing more!

Doesn’t feel like cotton! Sounds like a paper bag when you get into bed!

Should've Paid More Attention to Reviews

Originally posted on marksandspencer.mom (UK)

No, I don't recommend this

I expected the sheet to be great but it actually felt like taffeta rather than good cotton. Hoped it would wash up well but the creases were dreadful and didn't go with super steam/hot iron. They make a rustling sound in bed like there's an invisible bag of crisps somewhere you just cannot get rid of. Would not recommend and would take back for refund if possible.

Not brilliant white

Originally posted on marksandspencer.mom (UK)

I don’t like the finish on these sheets. They are advertised as Egyptian cotton but not as sateen with a shiny finish. Also when folded they have a yellow hue which is not true white. Do t think I’ll be ordering these again
