Excellent – Very comfortable, keeps its shape --soft--not hot--last a long time--would buy another at any time, even though they are dear. Soft but comfortable --never loses it's shape. Had it for Many years now maybe 9 or 10. I take it with me whenever I go away as couldn't sleep on another. The price.I notice when I change the protector it has become a bit crumbly, however it does not effect the comfort.
