Abstract
A seating, including a sling seating, can have adjustable and/or non-adjustable cushions. An occupant of the seating can adjust the thickness and support provided by an adjustable cushion. The adjustable cushion can include an open cell foam in an airtight envelope. The occupant can open a control valve connected to the envelope to let air out of the airtight envelope while the occupant applies external pressure to the open cell foam, which decreases the thickness of the adjustable cushion as the open cell foam compresses. The occupant can close the valve to restrict airflow into and out of the envelope at a desired thickness of the adjustable cushion. The occupant can subsequently open the valve to let air into the envelope while the occupant does not apply external pressure to the open cell foam, which increases the thickness of the adjustable cushion as the open cell foam expands.
