Abstract

A seat assembly comprising generally an outer air cushion and an inner air cushion provided therein. The outer air cushion includes three rings superposed and fixed together, each ring having an air tap. A diameter of the lower ring, when taken in cross section, is larger than a diameter of the upper ring which is larger than a diameter of the middle ring. The inner air cushion is expanded and is limited within the outer air cushion when a user is seated thereon. The inner air cushion completely absorbs a weight of the user and is deformed according to a body of the user so that the user may feel comfortable.
