I haven't been able to sleep through the night since my mom past in October 2019, let alone waking up to severe back pain for both me and my boyfriend since we purchased our new mattress. When I opened my topper I didn't notice any odor like they warn you about. Plus I was so excited when it finally came, there was no way I was gonna wait another second to put it on our bed. For the last four nights not only have both my boyfriend and I slept through the night but we actually feel rested when we get up in the morning. And no more back pain!!! I would absolutely recommend this topper without ANY hesitation. I was nervous to try and buy something for my bed that I couldn't actually touch in person but I am SO please that I found this little gem and went with my gut and tried it. You will be too!
