Fantastic pillow, especially removing one of the softer inserts to give structured neck support with a little give.

[This review was collected as part of a promotion.] The quality of this pillow impresses; however, it impresses also by how cooling it is. It has been the best pillow I’ve had, and I’ve experimented with loads. Not the cheapest, but great value given how vital sleep is for so many reasons.
