I have bought 3 different
I have bought 3 different (expensive) mattresses the past year and every single one caused me so much pain. I finally put this topper on my firm spring guest bed and I am FINALLY not waking up a million times a night in pain. I am so extremely happy to have found this topper. If you have hip pain or shoulder pain, I would recommend trying this topper out. I did add a 1-inch memory foam topper on top of it for right now, but as a heal I think I won't need this anymore.
