Bed frames / bases are traditionally sold by 'mattress size'. Which is the size of mattress a product is designed to take, NOT the dimensions of the product itself.
When choosing a bed frame, it's important to understand the the mattress will sit INSIDE the frame, meaning the frame will be ever so slightly bigger then the mattress.
