I don’t use a tumble drier and simply spun at lower than usual setting and hung to dry. Did not need ironing.

Silky smooth and certainly easy care. A winner, and good value despite seemingly high price

I love the 400 thread count. So soft and comfortable. Keep coming back for more, as our other bedding pales in comparison.

I love a flat sheet, so much easier than a fitted one . I always go a size larger so you get a good fold.

These were even better than I expected. Beautiful cotton and so silky smooth. They only needed a little ironing and I’m sure many wouldn’t bother. Very pleased.

Great value and super quality. Really lovely feel to this sheet & it washes well too. Really happy with my purchase - It's so nice to have a high quality sheet with a bit of substance to it next to your skin.

Really good quality sheet. Thick cotton so has a good weight helping it to stay flat. Definitely recommend.

Great quality sheet and silky smooth next to skin. We use a flat sheet under the duvet to save washing the duvet cover every week. Bought King size for a Super King size bed & it’s perfect.

U got the blush pink and once I’d washed it and put it on it just looked more brown than pink.

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.
