Purchased both the mattress topper & mattress protector after reading the advice on 'the wool rooms' website & have to say what a difference it's made. My rather firm & uncomfortable mattress is now much softer to sleep on. I would have given 5 stars but taken a point off as both items had faulty stitching. However, i have to say customer service were fantastic & delivered a new set two days later. One slight concern i'd like to raise, is that the delivery man asked a total stranger if she could sign & deliver them.............. Seems he couldn't be bothered to get out of his van & deliver them himself, fortunately she was an honest lady & brought them to my door.
