Long standing issues with pillows and poor sleep. Can't get used to memory foam, 2 pillows too high and 1 too low. These seemed different so thought I'd give it a go, as they have a 30 day satisfaction guarantee. Only had this pillow for a short while but feels great, hasn't lost it's shape and is very comfortable. It has a different feel due to sprung core, but very soft to lie on and so far so good. I would recommend. Customer experience also good and very good communication.
