Provided is a length-adjustable column with a standpipe having a longitudinal axis, a length-adjustment device arranged in the standpipe with a portion displaceably-mounted along the longitudinal axis with respect to the standpipe and an anti-rotation locking device for locking the portion against a rotation around the longitudinal axis relative to the standpipe. The anti-rotation locking device includes an inner element, which is fastened to an outer surface of the portion, and an outer element, which is fastened to an inner surface of the standpipe. The inner element cooperates with positive locking with the outer element against a rotation around the longitudinal axis, and is displaceably guided along the longitudinal axis by the outer element. The inner element is connected with the portion through a substance-to-substance connecting layer.

A storable dual-use table having a reversible desktop with a desk on one side and a pad on the other side to convert from a rehabilitation table to a desk by flipping the desktop over. The desktop can be stored apart from the support structure of desktop frame and legs. The table has height adjustable legs to provide different heights depending on whether the table is being used as a table or as a desk. A leg storing system allows the legs to be folded parallel to the desktop frame in order for the support structure to be compact for storage.

A device for table elevation includes: two decorative covers; two guiding bases connected by a connecting rod and each having four fixed sides; plural guide bearings provided in pairs, each pair arranged opposite, and at an angle with respect to, each other; two guide posts having plural guided sides corresponding in number and position to the fixed sides, the guided sides being in contact with the guide bearings so that the guide posts can slide with respect to the guiding bases respectively, the guide bearings abutting against the guided sides in the aforesaid pairs; two driving units each including an elevating rod; and a tabletop with a guide post fixing base fixed at the top ends of the guide posts and of the elevating rods so as to move vertically with the elevating rods and the guide posts while the decorative covers and the guide posts stay vertical and stable.
