IâĂĂ´m just not sure. My wife loves the pillow. I only like the pillow. We are both side & back sleepers. ItâĂĂ´s lofty & keeps its shape no matter how much you move around. It conforms in any way you want it to... I think thatâĂĂ´s my problem with it. Back when all I had was a down pillow, if I had found this alternative, I would have been the happiest sleeper ever. However, now I think I prefer a pillow that is more substantial. But again, I like the pillow. I think I will keep it because it serves a purpose. It just wonâĂĂ´t be my only pillow. I will probably rotate. Also, it does get warm. Not as much as a regular down pillow would, but it holds heat. I really love the cover PG provides, but I had to put my âĂĂşsleep coolâĂĂš cover over it. Hopefully I can update this review in another 2 weeks with more positive feedback.
