A removable, pressure-adjustable, shock-absorbing cushion device for sports goods, comprising a cover and an air cushion enveloped in the cover. The cushion is a hollow flat bag having upper and lower sheets adhered to each other at round recesses or linear recesses, either alone or in combination.

An inflation pump or an air nipple is provided in the cushion for inflating or deflating the cushion.
