We had a regular spring mattress for years, but it was getting old and was kind of small (full size). We decided to upgrade. Now I have lower back pain, so I wanted a comfortable and supportive mattress. I wasn't sure how I felt about getting a Memory Foam Mattress, but the wife was insistent. We got it and at first it felt kind of stiff, it was a weird sensation. After the first night though, I was sold. I sleep much better and my back isn't as sore. I really love it.
