We need a new mattress. I compared a lot of them online and finally decided to buy this one. First of all, I don't like very soft mattresses. This is just right for me. It's not going to be very soft and very comfortable. The 10inch is also good for my new bed frame. The price is great, too! I think this is a very happy thing for me. I sleep very well because of it. My husband has low back pain and he feels very comfortable in this bed. Waking up in the morning is not so painful. We all like the new mattress
