Well, *anj* our last 2 mattresses have been from The Denver Mattress Co. one was a free replacement. That said, the new one is less than three years old and needs replacing...And I'm not getting the free replacement this time. They start out great, but quickly turn on you.
My ds has a mattress from another local company that is awesome. They have a web site and the beds with stats and prices are all there on-line. I went in, showed them my picture and asked for delivery. I'll be getting our new bed from them. They are a factory/seller and make the beds there on site.
