The self-stabilizing KT22 twin-pedestal table base provides a stable footing for rectangular table tops up to 30x55in in size. This model benefits from height-adjustable posts that raise or lower the table from 27.6in to 40.75in in height with the press of a lever. Fitted with a safety pin to help avoid unwanted adjustment, this height adjustable model provides great stability on uneven surfaces and allows users to conveniently adjust the table's height in seconds.
