I have purchased King size duvets (all season), wool pillows, mattress and pillow covers and am really pleased. It took a while to get used to the wool duvet as I have been using a down/feather duvet for many years. I find when using the 2 duvets together they still un pop. It will be interesting when the duvets need washing as my machine is not large enough & whether I trust the laundrette to wash it with care might mean the option of having it dry cleaned. However I have purchased (not from you as you do not sell them but might consider) is a 100% cotton duvet protector
