I love this topper! I bought a mattress from Wayfair, and thought I got a mattress that was neither too soft or too firm. Well, it did not soften up with time, and it turned to be more on the firmer side. Thankfully, this topper has saved my mattress. I am a side and back sleeper, and I have slept better than a baby. I also have mild lower back pain, and this has helped so much. Best 70 dollars I have spent!
