This product has been a lifesaver. After going without more than 3 hours of sleep at a time for nearly a year, I can finally sleep through the night. I have excruciating sciatica pain and this topper eases the pressure points allowing me to take less medication and avoid waking in the middle of the night. It's like sleeping on a cloud. Thought about buying a new mattress, but decided to give this a try first. I love it!!!
