Abstract
A height adjustable structure comprises a base, a height adjustment column disposed above the base and supported thereon, and a table top or chair seat support disposed above the height adjustment column. Alternatively the height adjustable structure comprises two or more base sections, a height adjustment column disposed above each base section and supported thereon, and a table top or chair seat support disposed above the height adjustment columns. Each height adjustment column comprises a telescoping spring height adjustment lifting mechanism. The telescoping spring height adjustment lifting mechanism is typically a gas spring. Actuation mechanisms which actuate or unlock each lockable telescoping spring height adjustment lifting mechanism are used to allow the user to easily make height adjustments. The actuation mechanisms may extend above the table top. Connecting bars may be used to connect more than one actuation mechanism.
