My back is in terrible shape right now and I decided to get a new mattress. I have wanted a certain brand for quite some time with all the bells and whistles, but it is simply out of my price range now. I started shopping for inexpensive mattresses and was wary of mattresses in a box. However, I called the furniture store where we usually shop, and the salesperson told me that now most mattresses do come in a box. (And by that, she meant the kind that you have to unroll and allow to inflate.) I ordered one and hope it's good or will at least relieve some of my pain. Does anyone else have one? What are your thoughts?
