Unbelievable quality

Fantastic at helping you stay cool through the night during hot weather or keeping you cool if you’re suffering from flushes because of the menopause. I won’t use anything else on our beds now. Really lovely quality to sleep under.

The sheet was a real help during the previous heatwave and made sleeping that bit easier than it would have been! Lovely quality too.

I had already bought the Stay Cool Lyocell Rich fitted sheet and pillow cases and liked the soft comfortable cool silky feel. With the hot weather I jettisoned my summer quilt and went for the Lyocell flat sheet to complete the look and stay cool on those hot summer nights. Highly recommended

Absolutely enormous sheet

Incentivised review originally posted on marksandspencer.com (UK)

Bought to use as top sheet when too warm for the duvet. Plus points, nice material " silky" feel with some body to it so drapes well. Stay Cool technolgy really does work - particularly when teamed with a Stay Cool fitted bottom sheet. Minus point is the sheet is enormous. Have to tuck a good 4feet of sheet under bottom of mattress and sheet hangs down to touch floor on both sides. Washing, drying and folding sheet will be challenging. With hindsight, I should have bought a sheet size smaller

Next best thing to Comfortably Cool sheets.

Incentivised review originally posted on marksandspencer.com (UK)

Yes, I recommend this

When it is crazily hot you don't need anything but I wanted the lightest of covers for the slightly cooler nights. It is soft and cool. I prefer the 'comfortably cool' range but that doesn't seem to be available any more. So this is the next best thing. A King Size flat 'over' sheet is plenty big enough for a Super King bed in my opinion. The Super K is unnecessarily big (unless you want to tuck the cover sheet properly around the mattress in cooler weather).

I was sceptical about the description of stay cool, however it does to a point. Would buy more

In the heatwave, the perfect sheet to have on the bed. Good size for a king size bed. Pleased I had bought 2 sheets , as they wash well and feel soft on the bed. Would recommend to family and friends.

Love these stay cool sheets and pillowcases. Work a treat with heatwave we’ve been having. Lovely cool crisp feel. This is the second set I bought for another family member as was so satisfied with the kingsize set purchased for my own bed 😀

Got this sheet on a sparks offer, so jumped on it. It is noticeably softer than other sheets I have and an absolute godsend in this weather.
