Query: Like sleeping on a rock

I thought this pillow would be comparable to a tempurpedic pillow, but I was in for a surprise. This pillow was so dense that it was not comfortable at all. My head could not even sink into it and the foam didn't even conform to my head to allow support where it was needed. It was also very high and pushed my head upward which actually put more strain on my neck. Furthermore this pillow is very very heavy. Amazon offered a reimbursement for me as long as I paid the return shipping and handling, but that would've cost me more than I paid for the pillow itself. So now I am stuck with this paper weight of a pillow shoved in my closet, never to be used again.
