A mattress assembly for supporting a patient includes a body support portion having a head end, a foot end, and a knee support portion. The body support portion has a first air zone extending from the head end to the knee support portion and a second air zone extending from the knee support portion to the foot end. The mattress assembly also includes a control module configured to supply air to the first and second air zones to maintain the first air zone at a substantially constant first pressure and to maintain the second air zone at a substantially constant second pressure. The second pressure is less than the first pressure to provide reduced pressure on a patient's calves and feet located on the second air zone.
