Abstract
An adjustable gas pressure spring includes a gas pressure spring portion, a gas reservoir and a connecting means fluidically connecting the gas reservoir and the gas pressure spring portion with each other. The spring force of the gas pressure spring portion is adjustable by means of pressure equalization with the gas reservoir and/or the ambient pressure. Such a gas spring is provided in an adjustable column, in particular an adjustable table column. The table column is in turn provided in a height-adjustable table.
