Disclosed is a height adjustable stand for supporting an object, such as a table leaf or a camera. The invention also relates to a table including the stand. The stand includes at least a first leg, at least a first locking device and at least a first central operating device including at least a first elongated operating element that is arranged to allow the first locking device to be transferred from a locked resting state to an unlocked state in which the height of the stand is adjustable. The construction of the stand is lean and robust allowing height adjustment and stable positioning of the stand and thereby the table, even on uneven supporting surfaces simultaneously. User comfort is improved as precious time can be saved especially when installing multiple stands or tables.

Systems and methods for adjustable telescopic support rods are provided. Specifically, the telescopic support rods in accordance with some embodiments comprise selectably modifiable indexed lengths having no externally visible indication of the indexing means. Methods for modulating the length of the support rod and its use in, for example, vertical support for scaffolding and shelving units are also provided.
