To be honest I was doubtful anything would help. I have had spine surgery titanium rod and pedicule screws and nowhere was comfortable pain and pressure pain. Bought the mattress topper after another painful sleepless night and after putting on bed fresh bedding slept uninterrupted for 6.5 hours no pain. I am over the moon to say the least and if l could, I'd do somersaults (that's not going to happen) truly sceptic thought maybe time for new mattress but topper has proved me wrong. I looked at all the options and this one was out of two shortlisted for comparison. I'm so glad I made the final choice I feel like Goldilocks as its "just right" it's actually perfect for me. Would definitely recommend 5 stars 🌟 🌟🌟🌟🌟
