I had to replace my old mattress as I could never get comfortable and never slept well through the night. I went to many stores and tried out so many beds. This mattress was by far the most comfortable to me and my aches and pain. I have a bad neck, shoulders, back, and hips. I was worried to spend so much on a bed, but took a leap of faith and I'm so glad I did. I sleep so well despite all my aches and pains because the mattress conforms to me. I definitely thought at first that it was not the right bed for me, but after a week, it seemed to break it and it's been perfect sense! I owe my better sleep to Tempurpedic!
