I was kinda skeptical about buying this mattress topper because I wasn’t sure how well it would work or if it would really make a difference, and it did. I’ve been waking up almost every day with side or back pain, but ever since I started using this mattress topper, I noticed my back doesn’t hurt as much anymore. And I’m glad it stays in place and that it fits under my fitted sheet. I’ve been able to fall asleep faster without tossing and turning like I’m used to. So glad I took a chance and bought this mattress topper.
