You can place your Big Fig Mattress on top of any bed, box spring or other surface that you choose. But in order to maintain the comfort and integrity of your mattress, especially for bigger figure sleepers, it must be able to evenly and properly support the weight.
Unfortunately, we don’t know of any boxspring on the market that can make this claim. If you are able to find a boxspring or foundation that is guaranteed to support at least 1,220 lbs. (the weight of a Big Fig Mattress + 2 sleepers weighing a total of 1,100 lbs.), it could be a viable option to use under a Big Fig Mattress.
