An air cushion, including the gasbag spring of any one of claims 1-6 and assemble the base of location for the gasbag spring, characterized in that, the base includes basic unit (7) and superpose overburden (8) on basic unit (7), basic unit (7) and overburden (8) enclose to close and form sealed air flue (9), sealed air flue (9) lead to with the external world through trachea (10), the gasbag spring erects the gesture overlap joint in the base top with the axis and with sealed air flue (9) lead to even to make trachea (10) right through sealed air flue (9) the gasbag spring carries out synchronization regulation.

9. The air cushion as claimed in claim 8, wherein the cover layer (8) is provided with a connecting hole, the air bag spring is adhered to the cover layer (8) through the bottom surface and is in sealed butt joint with the connecting hole through the inflating hole (1); or the covering layer (8) forms the bottom wall of the airbag spring, so that the inflation hole (1) is formed in the covering layer (8); or the base comprises a plurality of rows of long-strip-shaped sealing air passages (9) which are equidistantly arranged, and the air bag springs are equidistantly arranged along the sealing air passages (9), so that the air cushion can be divided into a plurality of independently adjustable subareas.

10. A mattress comprising an air mattress (11) according to any one of claims 8-9, wherein the outer edge of the air mattress (11) is provided with a peripheral edge (12), and the top surface of the air mattress (11) is covered with a comfort layer (13).
