Egyptian cotton silky sheet

Originally posted on marksandspencer.com (UK)

Good quality sheet but not as silky as expected, not washed yet so may soften up

Very good size, great value for money. Was dubious as to how silky it felt, but this is subtle. Haven't washed it yet.

Great flat sheet, goes with the rest of my Egyptian Cotton 400 count bed linen. I bought this to sleep under instead of a duvet for this hot weather. Does the job perfectly.

A bit prickly

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The sheet looks nice and feels nice. However, I have the matching pillow cases which I washed before use and they are very rough - almost prickly on my face. Very odd as they are 400 thread count. Maybe something they are treated with? So I decided not to take the risk on the sheet and returned it.

Nice silky feel to the sheet. Good quality. Bought it to go under the duvet so when it’s really hot I can just lie under a sheet!

Feel great, top sheet is spot on although the fitted sheet isn’t as tight on my mattress as they usually are

Soft & comfortable

Although this was quite expensive it was worth the money, it hardly creases even when you tuck it under your arms. Much better than their pure cotton, as they say “you get what you pay for “ I’m thinking of getting another one.

Yes, I recommend this

Bought with the fitted sheet and pillow cases and am very impressed by not only the quality of the fabric but also by the manufacturing quality.Extremely comfortable particularly during the recent warm nights.The colour is as expected from the online photos and they fit well. First impressions suggest that they should have a decent life span in which case they represent good value. Very pleased and intend to buy further sets.

Kingsize cotton sheet

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The cotton is beautiful and comfortable to sleep in. My one difficulty is that the sheet is enormous. I did order kingsize and it is this on the label but is definitely on the generous side.
