A task chair capable of forward and rearward synchronized movement with a base assembly, a linkage supported by the base assembly to pivot about an axis in relation to the base assembly, a seat assembly pivotally retained relative to the linkage, and a back assembly pivotally retained relative to the linkage. The linkage can include a bracket and a resiliently deflectable assembly retained relative to the bracket. A projection retained by the base assembly can engage the resiliently deflectable assembly whereby the linkage and the seat and back assemblies can pivot in relation to the base assembly. The linkage can have a bracket; a first link pivotally coupled at a first axis relative to the bracket, pivotally coupled at a second pivot axis relative to the seat assembly, pivotally coupled at a third pivot axis relative to the back assembly; and a second link pivotally coupled at a first axis relative to the bracket and at a second axis relative to the back assembly.
