摘要：On the one hand, the invention relates to a length-adjustable column (100) with a standpipe (110) with a longitudinal axis (LA), a length adjustment device (120) arranged in the standpipe (110) with one displaceable relative to the standpipe (110) along the longitudinal axis (LA) mounted portion (121) and an anti-rotation device for curing the portion (121) against rotation about the longitudinal axis (LA) relative to the standpipe (110). The anti-rotation device compris an inner member (140) fixed to an outer surface of the portion (121) and an outer member (130) fixed to an inner surface of the upper tube (110). The inner element (140) interacts positively with the outer element (130) in relation to a rotation about the longitudinal axis (LA) and is displaceably guided by the outer element (130) along the longitudinal axis (LA). The inner element (140) is connected to the ction (121) by a material-bonding connection layer (160). The invention further relates to a method (200) for producing an adjustable-length column (100) comprising the steps of: providing (210) a length adjustment device (120 ) having a portion (121) and an inner member (140) of an anti-rotation device (160) having an inner ba body (141),
