The Deluxe Wool pillow has proved to be one of my 'best buys'. Despite my initial concerns : slightly expensive(?), will it be the right depth? will it provide a cooler pillow than my previous ones? (I'm a sweater). I needn't have worried - the depth 'issue' isn't a problem with the Deluxe as you can add or take away filling as required. It also proved to be great for my temperature & humidity control. Cost? It has proved worth the money - especially considering that we spend about a third of our lives resting our heads on pillows. I would recommend this product. If you have any doubts or are dissatisfied, this product (and other Woolroom products) have a 30 day refund guarantee.
