I've got a memory foam topper which helps loads with my back, definatly worth the investment. Spend the most money you can, there is a difference in exactly how much of the memory foam you get compared to more standard foam underneath.
The topper stank to high heaven for a few days too, but now smells of nothing, i think it was just the factory smell lingering on.
I want a full mattress, but can't afford it
