Yes, I recommend this

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

Flat sheet - ideal for when a duvet is too hot

Originally posted on marksandspencer.ie

Love the quality of the 400 thread count range. Like a silky sateen finish. I have numerous sets and colours in this range and wouldn't hesitate to buy more.

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

Convenient and smart.

Yes, I recommend this

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

Beautiful silky cotton

Yes, I recommend this

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.

Silky Smooth

Yes, I recommend this

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.

Nice but colour off

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