Bests & Worsts Reviews from Amazon

This mattress is horrible. I was so excited to get it and use it for my guest bedroom. We just finally got to open it and let it fluff up after moving and it was a bit bumpy at first. I tried to lay on it after two days and I rolled right off. There is a huge lump in the middle of the bed and then it just falls down, anyone rolls off the bed. It was such a waste of money and now I'm going to have to go out and buy another bed :( I'm not sure what to do with it now, I'm not sure if I'm the only one having this issue because most reviews I saw were great.
