I ordered the deluxe wool pillows late at night while lying in bed on "uncomfortable" pillows. I liked the idea of adjusting the filling and have a wool mattress topper so had high hopes for these. I have tried using 1 pillow , 2 pillows, full filling to very little filling and just about everything in between, even altering things in the middle of the night , but every night in the last 4 days since I had them I have had to revert to my old pillows during the night. They are definitely good quality and I'm sure they're perfect if you choose them for allergy reasons but for comfort they're just not for me. The have the same effect as memory foam ..feels great to start with but then just settles like a rock. Unfortunately £80 wasted for me as I can't send them back ( I misread the 30 day money back guarantee in my haste to order them )
