Abstract: A combination shelf includes a plurality of upright posts, a plurality of mounting sleeves each detachably mounted on the respective upright post, at least one mounting frame mounted between the upright posts and detachably locked onto the mounting sleeves, a plurality of mounting brackets each detachably mounted on the respective upright post, and a plurality of support boards mounted between the upright posts and supported by the mounting frame and the mounting brackets. Thus, the mounting brackets are detachably mounted on the upright posts to support the support boards so that the support boards are selectively mounted between the upright posts, and the number of the support boards can be adjusted freely and randomly according to a user's practical requirement.
