I've become severely allergic to my mattress and memory foam topper suddenly (at least I think suddenly). I need to buy a new mattress ASAP. One that is organic. Does anyone have a recommendation for one with a soft top? I like firm with a pillowtop, and I worry the latex will be too hard on my back. I am willing to invest in something for the long term so price is not an issue right now. Any suggestions would be great! I am desperate to take care of this ASAP as they usually take forever to order.
