I have been looking and researching mattresses longer than I want to admit. I decided to give this mattress a try and I'm so happy I did. I have back issues and I'm a large woman so I was concerned what type of mattress I should purchase. I fell in love the first night. I pray it holds up over time. This replaced a Serta that was a hand me down. Imo, you can't go wrong with Serta.
