When choosing the best mattress, you have to consider every aspect of the bed, from the dead center to the tips of the corners. Because, let's face it, we rarely spend a full night lying curled up in the middle of the mattress. If you ever wake up clinging to the side of the bed, then you need to think about edge support.
Edge support refers to how supportive the mattress is around the perimeter. Mattresses with good edge support are sturdy at the corners and along the edges, while mattresses with poor edge support sink when you sit down.
