400 Thread count is a real step up.

Yes, I recommend this

The 400 thread count quality is a real step up from the thin 250 in the existing range. I prefer the less silky feel, especially for winter months when 'silky' feels cold to the touch.

Lovely cool sleek feel, been a godsend in the heatwave. Exactly as described, colour is beautiful. Expensive so won't be buying another but definitely will if on offer.

The sheet is a lovely material. More greige than grey. We have a very deep mattress and was worried it wouldn't cover the depth but the sheet is huge and unfortunately it wrinkles underneath you as you sleep, it won't stay tight, it does stay on at the bottom but becomes uncomfortable to lie on.

Excellent fitted sheet - does Stay Put!

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This fitted sheet is perfect on our Deep Sealy mattress which also has a mattress topper on it. The all around strong elastication ensures that it really does ‘stay put’. The 400 thread count means that the fabric is lovely and smooth/soft to sleep on, and being a natural fibre too, keeps the bed cool. Bed making is so easy with this bottom sheet, just a quick smooth out - and you’re done! Highly recommended and would buy again.

Feels absolutely super and great fit. It definitely stays put with the elastic banding all of the away around the fitted sheet.

These are different from other fitted sheets I have purchased before. The large elasticated band sewn in took some getting used too. A part from this I am totally satisfied.

Lovely material

Originally posted on marksandspencer.com (UK)

The feel of he fabric is really comfortable. However, these sheets are not non-iron. In fact they take quite a lot of ironing. I do not have a tumble dryer so have to air dry sheets. The elastic all around the edge is far too much - it is difficult to find the "right way round" when putting them on the bed. They are not exactly "stay put" either, as they move as much as any other fitted sheets. So, nice quality, but only 4 stars.

Not as good quality as they used to be. Seems rougher to touch. Bought new as the one I had had worn a hole ! This is the second sheet from M&S that has worn a hole. M&S sheets used to last for ever.

Sadly this does NOT stay put on my mattress. However it does at least cover the whole of it unlike others which don’t seem to cover the sides.

Silky Fitted Egyptian Sheet

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Great Fitted Sheet, but since it's heavily elasticated all over every edge, it's not easy to fit onto the mattress. Also, because of that, it's hard to see which is to fit the mattress on the top/bottom edge of the sheet and which is to fit the sides
