I have been sleeping on this pillow for a month now and I cant tell you how much I love it. It conforms perfectly to my head and neck and I wake up with no neck pain that I usually have. It comes with extra filling so if you want it firmer you just add more.
My husband is pleased with this memory foam topper. He prefers a firm mattress and by adding this topper he still gets the firmness and support of the mattress, but also a soft layer that conforms to his body. He wakes up less stiff and sore than before and is more rested. Definitely two thumbs up.
