Abstract
An air cell provided for a mattress has two independent air chambers that are manufactured by die-casting at a same time. One of the independent air chambers is an adjustable air chamber, in which air can be alternately inputted and outputted through a pneumatic member to have the effect of promoting blood circulation of a person. The other independent air chamber is a supporting air chamber, which can support the body of the person with permanent air therein whenever the adjustable air chamber loses its function.
