    摘要: A rocking chair particularly suitable for use as a student desk chair as a seating surface, a back rest and a pair of generally parallel rocking rails. Preferably, the rocking chair has a relatively small footprint and has a relatively limited range of rocking motion. In one preferred, but not required embodiment, the pair of generally parallel rocking rails are both reverse cantilevered rocker rails.
