Bought these sheets because of all the great reviews. Worried when I first got them as they felt a bit scratchy so I washed them with bicarb and vinegar. Husband didn't seem too keen at first however once we both slept in them a couple of nights, we realised they are fantastic. Its hard to explain how comfortable they are. My husband and I can't believe that they keep you cool when its hot and warm when its cold! Going to buy my second set right now and doubt I will ever use any other sheets!!
