My previous purchase of a wool mattress protector enhanced my sleep but I was still some problems with my head overheating this has now been solved with my purchase of the deluxe wool pillows I purchased for myself and my husband. We are both now getting a more restful, cooler sleep. So much so, I have now got a second pair for our caravan, very grateful to have got them all in the sale but worth the money. I like a firm pillow but they are very adaptable as you can remove some of the filling if too hard for you, or purchase more filling should you wish them even firmer. I really like that you can completely remove the filling to wash the outer cover as well. I have asthma so no dust mites was another added attraction. The speed of delivery is fantastic as arrived next day in both case. Well don Wool Room a pleasure doing business with you.
