A flooring pedestal and acoustic flooring system including the pedestal is described which comprises a planar vibration absorbing panel supporting a substantially planar pedestal base plate having a threaded support pillar extending upwards from the base plate with a thread substantially along its full length and a substantially planar support plate having a centrally located threaded aperture, the support plate being threadably engaged onto the support pillar of the pedestal base so that it may travel substantially the full length of the support pillar. The pedestal may include a locking member. This arrangement enables low profile acoustic flooring to be laid with minimum preparation of the sub-flooring and disruption to the fabric of the building accommodating the acoustic flooring.
