Whatever you do DO NOT PURCHASE A RETURNED no warranty mattress here!!! I made the huge mistake and my back is killing me. There is nothing they can do to return or exchange it, because it's not part of the deal I signed. They've tried to pull me into the store to purchase ANOTHER new mattress, but I couldn't even afford the first one. Biggest financial mistake I've made in a long time, and I'll be paying for it for a very very long time with back pain and lack of sleep. I'm sure it's fine to buy new there, but please do not buy an already returned version. Stupid mistake!
