Until I found the Woolroom I had lived deprived sleeping life - why I never learnt about wool duvets before I do not know... I now can't wait for to get into bed! ;) I suffer from a conditional which at times makes me very hot and sweaty - I do not feel uncomfortable at all and can sleep right through the night sandwiched between a wool duvet, mattress protector and pillows... My husband doesn't toss and turn so much and we sleep better through the night. I purchased a superking all seasons duvet 300g + 200g - major downside is that the poppers aren't strong enough to keep the 2 duvets together. I'm thinking when winter arrived I may have to sew them together. The heavier duvet ( 300g ) is currently in use while it's spring - it's light in weight, while it's not a light fluffy cloud like duvet, it certainly is warm and drapes right around you. The wool pillows are quite firm, but label says every now and then you have to tear the wool apart to soften the pillows up - yet to try. The mattress protector is good and is deep enough for a 30cm mattress.
